MEANING OF THE LETTER TO THE SEVEN CHURCHES OF REVELATION PART SIX

The sixth church in the sixth year of Daniel’s 70th week is the Church of Philadelphia. The city’s name is derived from the Greek PHILADELPOS, meaning “love for a family member” or “love for a brother.” But what does it say about conditions in the Church of the same name during the Sixth Year of the 70th Week? What remains of the faithful Church will be bound in brotherly love by the persecution of earth-shaking proportions.

The Fifth Year of the 70th Week, which I covered in my last post about the Church of Sardis, is the year of the Great Falling Away. Massive numbers of nominal churchgoers will turn away from the faith when faced with persecution. They will bow to the Beast, his name, and take his number (the Mark of the Beast, likened to 666). The hour of testing the saints will be guarded from is the Wrath of God that occurs during the Seventh Year of the 70th Week.

These Christians will be living on the run, or they will go “underground,” totally weaned from the world economic system. Life in the Sixth Year of the 70th Week will be much like the First Century Church described in Acts; they’ll have all-things in common. Most will have lost family members, either to apostasy or martyrdom. They truly will be one family, the Family of God.

ATTRIBUTES OF JESUS IN THE LETTER TO PHILADELPHIA: In this Letter to Philadelphia, Jesus is described by the following attributes: “He who is holy, who is true, who has the key of David, who opens and no one will shut, and who shuts and no one opens, says this.” Revelation 3:7.

The first attribute about Jesus noted is that he is Holy. At the end of the Sixth Year of the 70th Week, Jesus is coming to separate the elect from this world by means of the Rapture. Then they will be “like him.”

The second attribute is that Jesus is true. In the Letter to Philadelphia, truth is contrasted with “lying.” Jesus is true, those of the synagogue of Satan are liars (Rev. 3:9, 1 John 2:22). Jesus is the true light (John 1:9), the true vine (John 15:1), the true Bread (John 6:32), and the way, the truth and the life (John 14:6). This attribute being “true” is critical. Those in the Sixth Year of the 70th Week can trust Jesus that he will save them at the appointed time. His word is true.

The third attribute is the most intriguing. Jesus has the key of David. In the last section, we saw a reference to doors that would open and not be shut in regard to Cyrus, who we learned is a type of Christ: “Thus says the Lord to Cyrus His anointed, whom I have taken by the right hand, to subdue nations before him and to loose the loins of kings; to open doors before him so that gates will not be shut“. Isaiah 45:1. Not only does Jesus open and shut the door, he is the door. “. I am the door; if anyone enters through me, he will be saved and will go in and out and find pasture. The thief comes only to steal and kill and destroy; I came that they may have life and have it abundantly.” John 10: 9-10. This passage clearly contrasts Jesus with the Antichrist (the thief). In the Sixth Year of the 70th Week, Jesus will use the key of David to open the door no one can shut, call to his sheep, and lead them out in the Rapture. The Key of David appears in the sixth letter in the sequence of seven letters. The Sixth Year of the 70th Week is the year of the Rapture. This is the year the Lord opens the door of heaven for the wise virgins.

CONDITION OF THE CHURCH OF PHILADELPHIA Jesus has nothing but compliments for these survivors of the Great Tribulation, his faithful remnant represented in the Letter to Philadelphia: “I know your deeds. Behold, I have put before you an open door which no one can shut, because you have a little power, and have kept my word, and have not denied my name… Because you have kept (Gk: TEREO, meaning to guard) the word of my perseverance (Gk: HYPOMONES, meaning endurance) also will I keep (Gk: TEREO, meaning to guard) you from the hour of testing (Gk: PEIRASMOU, meaning temptation, trial, or testing), that hour which is about to come upon the whole world, to test those who dwell on the earth.” Revelation 3:10

The context of this passage in the Letter to Philadelphia means that it is related to the Sixth Year of the 70th Week. Those who overcome are guarded against the “hour of testing” or trial, not the entire 70th Week of Daniel as the pre-tribulation rapture teaches. This is an important distinction. The brief hour of testing the saints will be protected from is the Wrath of God, the Trumpet and Bowl judgements, which occur during the Seventh Year of the 70th Week.

So, for six years of the 70th week of Daniel, the Saints will be on Earth doing the work God has called them to do, and the seventh year will be a sabbatical rest for the Saints in heaven. The Trumpet and Bowl judgements will last for one year and ten days, the same time as when God poured out His wrath the first time with Noah’s Flood. The year before a Jubilee year is always one year and ten days which indicates the year following God’s judgement will be a Jubilee Year.

The final post on the Meaning of the Letters to the Seven Churches of Revelation will be about the church of Laodicea, the church left behind to endure the wrath of God.

THE TIMING OF THE RAPTURE

Jesus promises that in the end times, there will be tribulation, even great tribulation before His return but believers will be kept from the wrath of God that is poured out on unbelievers at that time.

Dr. Baruch Korman of Love Israel Ministries (www.loveisrael.org) explains the timing of the rapture and the wrath of God is poured out with the Trumpet and Bowl judgements. What happens and who is involved when the seven seals are opened and the four horsemen are released is enlightening.

Christians will be on Earth for six years of the final seven. The Wrath of God with the Trumpet and Bowl judgements will take one year and ten days which just happens to be the same time as the time God poured out His wrath the first time with Noah’s flood. Why one year and ten days? The length of a year before a Jubilee year is always one year and ten days on the Hebrew calendar.

WHY AUSTRALIA WILL COME UNDER INCREASING JUDGEMENT OF GOD

Recent anti-God expenditures and legislation by State Governments will ensure further judgement on this nation by God.

NSW MLC John Ruddick has delivered a powerful speech to the state parliament about the excessive funding of rainbow activism. Up to $14 million and at least 22 agencies receive tax-payer funding to support their ‘neo-religion.’ Ruddick has called for government funding to cease and allow these groups to continue only if they can raise the funding themselves. He noted that organisations such as ACON (formerly known as the Aids Council of NSW) served their purpose during the AIDs epidemic but have since had to “invent new rainbow causes that are so important that the taxpayer has to fund them.” When lobby groups fight for a cause and win, they don’t just pack up their lobbying tents and go home. Too often they simply find new and more radical causes within the same framework. Lobbyists who rely on government grants do not simply pat themselves on the back after winning their cause – they get addicted to the gravy train.

Ashlyn Vice, SA Director of the Australian Christian Lobby (ACL), says Mr Hood’s Termination of Pregnancy Amendment (Terminations and Live Births) Bill was a “no-nonsense, compelling proposition to change the process of terminations post 28-weeks’ gestation – offering a pro-woman, pro-child compromise”. “Tonight’s result means more South Australian babies will be needlessly born dead when they could have been safely born alive,” Vice says. “If passed, this Bill would have ensured babies in their third trimester would be born alive by inducing early labour in circumstances where the mother insists on ending the pregnancy. This was to replace current practice, which is to kill the baby via a lethal potassium chloride injection before inducing labour.” Vice says.

Our elected government leaders have no fear of God which reveals the godless state of our nation and an inept church. A church that no longer upholds the inerrancy of God’s Word and heeds the many warnings and signs given of God’s coming judgement when He pours out His wrath upon an unrepentant world with the Trumpet and Bowl judgements.

Read the first four Trumpet judgements and know that the intensity only escalates as God pours out His wrath with the seven Trumpet and seven Bowl judgements. How many churches are warning the world of this soon coming judgement of God?

“The first angel blew his trumpet, and there followed hail and fire, mixed with blood, and these were thrown upon the earth. And a third of the earth was burned up, and a third of the trees were burned up, and all green grass was burned up.
The second angel blew his trumpet, and something like a great mountain, burning with fire, was thrown into the sea, and a third of the sea became blood. A third of the living creatures in the sea died, and a third of the ships were destroyed.
The third angel blew his trumpet, and a great star fell from heaven, blazing like a torch, and it fell on a third of the rivers and on the springs of water. The name of the star is Wormwood. A third of the waters became wormwood, and many people died from the water, because it had been made bitter.
The fourth angel blew his trumpet, and a third of the sun was struck, and a third of the moon, and a third of the stars, so that a third of their light might be darkened, and a third of the day might be kept from shining, and likewise a third of the night.
” Revelation 8: 7-12

GODLESSNESS IN THE LAST DAYS

Like many others in the O.T. and N.T., the following Scripture warns us about what will happen before Jesus returns to restore righteousness. We cannot say that God has not told us what is ahead

“But understand that in the last days, there will come times of difficulty. For people will be lovers of self, lovers of money, proud, arrogant, abusive, disobedient to their parents, ungrateful, unholy, heartless, unappeasable, slanderous, without self-control, brutal, not loving good, treacherous, reckless, swollen with conceit, lovers of pleasure rather than lovers of God, having the appearance of godliness, but denying its power. Avoid such people. For among them are those who creep into households and capture weak women, burdened with sins and led astray by various passions, always learning and never able to arrive at a knowledge of the truth. Just as Jannes and Jambres opposed Moses, so these men also oppose the truth, men corrupted in mind and disqualified regarding the faith. But they will not get very far, for their folly will be plain to all, as was that of those two men.” 2 Timothy 3:1-17

The Bible lists several events that will lead to the great tribulation period. Humanity will increasingly adopt a negative attitude toward God’s laws and reject keeping them. This lawlessness will cause people to greatly lack mercy, forgiveness, and love..

“Then they will deliver you up to tribulation and put you to death, and you will be hated by all nations for my name’s sake. And then many will fall away and betray one another and hate one another. And many false prophets will arise and lead many astray. And because lawlessness will be increased, the love of many will grow cold. But the one who endures to the end will be saved. And this gospel of the kingdom will be proclaimed throughout the whole world as a testimony to all nations, and then the end will come.” Matthew 24:9-14

It will be a trying, testing time but note the gospel of the kingdom is proclaimed throughout the whole world so God has His disciples doing the work they’re called to do right up to the time God raptures the Saints to heaven and pours out His wrath upon an unrepentant world with the Trumpet (Revelation 8) and Bowl judgements (Revelation 16).

WHERE IS IRAN IN BIBLICAL PROPHECY?

The video below by the evangelist, Tim Shuttlesworth is worth watching. He knows where we are in Biblical history and the importance of Biblical end-times prophecies to prepare us for the coming tribulation. As we continue to watch the retaliations in the Israel-Iran war, the disinformation presented on social media, biased news outlets, antisemitic narratives on college campuses, and sadly the uneducated dialogue of many Christians falls short of a proper Biblical view. All students of the Bible need to be able to understand this war against Israel through the tense of Bible Prophecy. Tim does a worthwhile job of addressing the ongoing developments and provides a prophetic map that reveals exactly where we are headed. He covers three questions:

1. What is the timeline of the current war we are watching in the Middle East?

2. Where is Iran in Bible Prophecy?

3. What is Iran’s role in Final Bible Prophecy? Key Scriptures for today’s teaching: Ezekiel 39:1-7 Other Scriptures in this study: Ezekiel 38 & 39, Deuteronomy 33:29, Psalm 121:4-5 & 7, Isaiah 46:6b, Zechariah 9:16

I do not agree with Tim’s timing of the Rapture. He believes that the rapture happens before the start of tribulation which begins with the opening of the first seal, at year one of the final seven years of this era.

God does not say He will keep us from persecution/tribulation but He does say He will keep us from the time when He pours out His wrath upon the earth. The wrath of God is poured out with the Trumpet and Bowl judgements which commence at the blowing of the trumpet at the opening of the seventh seal at the end of the sixth year. At the sixth seal, we get the following Scripture announcing that the great day of God’s wrath has come.

“Fall on us and hide us from the face of him who is seated on the throne, and from the wrath of the Lamb, for the great day of their wrath has come, and who can stand?” Revelation 6:16

GET RIGHT WITH GOD BECAUSE GOD’S JUDGEMENT IS COMING

On the Feast of Trumpets, Jonathan Cahn opens up the different realms of end-time prophecy and matches it up with the stories and headlines of the day. Learn about the significance of Rosh Ha Shannah and the special celebration that includes the blowing of the shofar.

What happens when the trumpets are blown in Revelation? Judgements happen. The trumpet and Bowl judgements are escalating in severity. During those judgements, people have the opportunity to repent and accept Jesus as their Saviour and Lord. There are seven Trumpet and seven Bowl judgements. I will give the Scriptures covering the first Trumpet and first Bowl judgements. You do not want to be on Earth during that time. Christians are raptured to heaven before the wrath of God is poured out with the Trumpet and Bowl judgements.

“And the seven angels which had the seven trumpets prepared themselves to sound.
The first angel sounded, and there followed hail and fire mingled with blood, and they were cast upon the earth: and the third part of trees was burnt up, and all green grass was burnt up
.” Revelation 8:6-7

“And I heard a great voice out of the temple saying to the seven angels, Go your ways, and pour out the seven bowls of God’s wrath upon the earth.
And the first went, and poured out his bowl upon the earth; and there fell a noisome and grievous sore upon the men which had the mark of the beast (Antichrist), and upon them which worshipped his image.
” Revelation 16:1-2

“For the Lord Himself will descend from heaven with a shout, with the archangel’s voice, and with the trumpet of God, and the dead in Christ will rise first. Then we who are still alive will be caught up together with them in the clouds to meet the Lord in the air and so we will always be with the Lord.” 1 Thessalonians 4:16-17

A WAKE UP CALL FOR CHRISTIANS

The following verse from Revelation should be a wake-up call for all Christians. John is given this revelation about the final 3 1/2 years before Jesus returns to Earth for the battle of Armageddon. The Antichrist is allowed by God to exercise authority over the Earth and to wage war against the Saints.

“If anyone has an ear, let him hear: If anyone is to be taken captive, to captivity he goes; if anyone is to be slain with the sword, with the sword must he be slain. Here is a call for the endurance and faith of the saints.” Revelation 13:9-10

Surely, for nonbelievers, these prophetic Scriptures prove the Bible is the inspired word of God. Who would follow a God who allows his enemy to slay His followers? Only born-again believers who have received the Holy Spirit can understand and obey this instruction to endure even unto death.

“And the beast (Antichrist) was given a mouth uttering haughty and blasphemous words, and it was allowed to exercise authority for forty-two months. It opened its mouth to utter blasphemies against God, blaspheming his name and his dwelling, that is, those who dwell in heaven. Also, it was allowed to make war on the saints and to conquer them. And authority was given it over every tribe and people and language and nation, and all who dwell on the earth will worship it, everyone whose name has not been written before the foundation of the world in the book of life of the Lamb who was slain.” Revelation 13:5-8d

THE GOOD NEWS: The following words are written to the church of Philadelphia, the sixth church, the church that is raptured by God at the end of the sixth year before He pours out His wrath upon an unrepentant world with the Trumpet and Bowl judgements.

“And to the angel of the church in Philadelphia write: ‘The words of the holy one, the true one, who has the key of David, who opens and no one will shut, who shuts and no one opens. “‘I know your works. Behold, I have set before you an open door, which no one is able to shut. I know that you have but little power, and yet you have kept my word and have not denied my name… Because you have kept my word about patient endurance, I will keep you from the hour of trial that is coming on the whole world, to try those who dwell on the earth. I am coming soon. Hold fast what you have, so that no one may seize your crown.” Revelation 3:10-11

This word given to the church of Philadelphia is so different from the word given to the church of Laodicea, the seventh church, which is left behind to face the Trumpet and Bowl judgements.

“And to the angel of the church in Laodicea write: ‘The words of the Amen, the faithful and true witness, the beginning of God’s creation. “‘I know your works: you are neither cold nor hot. Would that you were either cold or hot! So, because you are lukewarm, and neither hot nor cold, I will spit you out of my mouth. For you say, I am rich, I have prospered, and I need nothing, not realizing that you are wretched, pitiable, poor, blind, and naked.” Revelation 3:14-17

The good news for these people left behind to face the wrath of God is they still have a chance to repent and be saved.

“I counsel you to buy from me gold refined by fire, so that you may be rich, and white garments so that you may clothe yourself and the shame of your nakedness may not be seen, and salve to anoint your eyes, so that you may see. Those whom I love, I reprove and discipline, so be zealous and repent.” Revelation 3:18-19

Each of the seven seals and each of the seven churches reveals what transpires on Earth during the final seven years before Jesus returns to Earth. It is at the sixth seal and the sixth year, when the celestial signs appear in the sky and we are told the great day of God’s wrath has come.

“Fall on us and hide us from the face of him who is seated on the throne, and from the wrath of the Lamb, for the great day of their wrath has come, and who can stand?”

It is the sixth church, the church of Philadelphia that is raptured at the end of the sixth year.

It is immediately after the sixth seal that the four angels are told not to pour out God’s wrath upon the Earth until the 144,000 Jews, servants of God are sealed on their foreheads.
“Do not harm the earth or the sea or the trees, until we have sealed the servants of our God on their foreheads.” And I heard the number of the sealed, 144,000, sealed from every tribe of the sons of Israel:” Revelation 7:3-4

Next John sees all those who were raptured standing before the throne of God the Father and Jesus.

“After this, I looked, and behold, a great multitude that no one could number, from every nation, from all tribes and peoples and languages, standing before the throne and before the Lamb, clothed in white robes, with palm branches in their hands, and crying out with a loud voice, “Salvation belongs to our God who sits on the throne, and to the Lamb!” Revelation 7:9-10

It is only after this scene, that the seventh seal is opened and the first of the seven trumpets is blown initiating the seven Trumpet judgements.

THE CHURCH THAT IS LEFT BEHIND TO FACE THE WRATH OF GOD

Televangelist Keith Moore’s ministry Faith Life International has purchased a third jet following a fundraising campaign to raise $10 million. The used Dassault Falcon 7X jet acquired by Moore’s ministry was listed for sale at $17.5 million, while a new model would have cost $60 million.

In addition to the Falcon 7X, Faith Life International also owns a Dassault Falcon 900 EX (tail number N7KM) and Raytheon 390 (tail number N8PJ) jets. Moore is a licensed pilot and certified to fly all three jet models; however, both Falcon jets require an additional pilot in the cockpit.

Creflo Dollar’s new Gulfstream G550: After televangelist Creflo Dollar asked for 200,000 donors to give $300 each to fund the purchase of a new $65 million Gulfstream G650 jet back in 2015, he faced an immediate backlash due to critical international news coverage. Instead of purchasing the Gulfstream G650, Dollar’s property holding company, World Heir, acquired two used jets: a Gulfstream G-IV (tail number N878SM) and a Learjet 60 (tail number N978SM), which was recently sold.

Why can’t these churches see that they fit God’s description of the church at Laodicea? It is the seventh church representing the church in the seventh year of the 70th Week of Daniel, the final year before Jesus returns to Earth with resurrected Saints to fight the battle of Armageddon and usher in His Millennial Kingdom (http://www.millennialkingdom.net) The church of Laodicea is left behind to face the wrath of God that is poured out with the Trumpet and Bowl judgements over the final year. The sixth church, the church of Philadelphia, is raptured and kept from the wrath of God.

CHURCH OF LAODICEA: LEFT BEHIND TO FACE THE WRATH OF GOD

“‘I know your works: you are neither cold nor hot. Would that you were either cold or hot! So, because you are lukewarm, and neither hot nor cold, I will spit you out of my mouth. For you say, I am rich, I have prospered, and I need nothing, not realizing that you are wretched, pitiable, poor, blind, and naked.” Revelation 3:15-17

CHURCH OF LAODICEA: “BE ZEALOUS AND REPENT“

“I counsel you to buy from me gold refined by fire, so that you may be rich, and white garments so that you may clothe yourself and the shame of your nakedness may not be seen, and salve to anoint your eyes, so that you may see. Those whom I love, I reprove and discipline, so be zealous and repent. Behold, I stand at the door and knock. If anyone hears my voice and opens the door, I will come in to him and eat with him, and he with me.” Revelation 3:18-20

CHURCH OF PHILADELPHIA: “KEPT FROM THE HOUR OF TRIAL”

“‘I know your works. Behold, I have set before you an open door, which no one is able to shut. I know that you have but little power, and yet you have kept my word and have not denied my name... Because you have kept my word about patient endurance, I will keep you from the hour of trial that is coming on the whole world, to try those who dwell on the earth.” Revelation 3:8,10

UNDERSTANDING THE DAY OF THE LORD

The phrase “Day of the Lord” usually identifies events that take place at the end of history (Isaiah 7:18-25) and is often closely associated with the phrase “that day.” One key to understanding these phrases is to note that they always identify a period during which God personally intervenes in history, directly or indirectly, to accomplish some specific aspect of His plan particularly Jesus second coming and a time when God will pour out His wrath upon the unrepentant as He did with Noah’s flood.

“But watch yourselves lest your hearts be weighed down with dissipation and drunkenness and cares of this life, and that day come upon you suddenly like a trap. For it will come upon all who dwell on the face of the whole earth.“ Luke 21:34-35

“For as in those days before the flood they were eating and drinking, marrying and giving in marriage, until the day when Noah entered the ark, and they were unaware until the flood came and swept them all away, so will be the coming of the Son of Man.“ Matthew 24:38-39

“But know this, that if the master of the house had known in what part of the night the thief was coming, he would have stayed awake and would not have let his house be broken into. Therefore you also must be ready, for the Son of Man is coming at an hour you do not expect.” Matthew 24:43-44

“But the day of the Lord will come like a thief, and then the heavens will pass away with a roar, and the heavenly bodies will be burned up and dissolved, and the earth and the works that are done on it will be exposed. Since all these things are thus to be dissolved, what sort of people ought you to be in lives of holiness and godliness, waiting for and hastening the coming of the day of God, because of which the heavens will be set on fire and dissolved, and the heavenly bodies will melt as they burn!” 2 Peter 3:10-12

“For they are demonic spirits, performing signs, who go abroad to the kings of the whole world, to assemble them for battle on the great day of God the Almighty. (“Behold, I am coming like a thief!” Revelation 16:14-15

The Old Testament passages dealing with the day of the Lord often convey a sense of imminence, nearness, and expectation: “Wail, for the day of the Lord is near!” (Isaiah 13:6); “For the day is near, even the day of the Lord is near” (Ezekiel 30:3); “Let all who live in the land tremble, for the day of the Lord is coming. It is close at hand” (Joel 2:1); “Multitudes, multitudes in the valley of decision! For the day of the Lord is near in the valley of decision” (Joel 3:14); “Be silent before the Lord God! For the day of the Lord is near” (Zephaniah 1:7). This is because the Old Testament passages referring to the day of the Lord often speak of both a near and a far fulfillment, as does much of Old Testament prophecy. Some Old Testament passages that refer to the day of the Lord describe historical judgments that have already been fulfilled in some sense (Isaiah 13:6-22; Ezekiel 30:2-19; Joel 1:15, 3:14; Amos 5:18-20; Zephaniah 1:14-18), while others refer to divine judgments that will take place toward the end of the age (Joel 2:30-32; Zechariah 14:1; Malachi 4:1, 5).

The New Testament passages call it a day of “wrath,” a day of “visitation,” and the “great day of God Almighty” (Revelation 16:14) and refers to a still future fulfillment when God’s wrath is poured out on unbelieving Israel (Isaiah 22; Jeremiah 30:1-17; Joel 1-2; Amos 5; Zephaniah 1) and on the unbelieving world (Ezekiel 38–39; Zechariah 14). The Scriptures indicate that “the Day of the Lord” will come quickly, like a thief in the night (Zephaniah 1:14-15; 1 Thessalonians 5:2), and therefore Christians must be watchful and ready for the coming of Christ at any moment.

Besides being a time of judgment, it will also be a time of salvation as God will deliver the remnant of Israel, fulfilling His promise that “all of Israel will be saved” (Romans 11:26), forgiving their sins and restoring His chosen people to the land He promised to Abraham (Isaiah 10:27; Jeremiah 30:19-31, 40; Micah 4; Zechariah 13). The final outcome of the day of the Lord will be that “the arrogance of man will be brought low and the pride of men humbled; the Lord alone will be exalted in that day” (Isaiah 2:17). The ultimate or final fulfillment of the prophecies concerning the day of the Lord will come at the end of history when God, with wondrous power, will punish evil and fulfill all His promises.

Much of the above comes from the website: http://www.gotquestions.org. It is a great place to go for answers to Biblical questions.

MORE ON THE COMING RAPTURE OF THE SAINTS

The Book of Revelation clearly shows a chronological order to the Resurrection and Rapture. Who are the first and who are the last to be caught up? What criteria does Jesus use? Does the Rapture truly happen in the twinkling of an eye, or is that a myth? Watch Nelson Walters’s groundbreaking video and discover if the last are first and the first are last as Jesus says.

This video does not address the timing of the Rapture which Nelson and I would put at the opening of the seventh seal which is the PreWrath Rapture position. Christians will go through much of the tribulation even great tribulation but will not experience the wrath of God which is poured out on the unrepentant with the Trumpet and Bowl judgements. Note it is in Revelation 6, at the sixth seal, we see the celestial signs that precede Jesus’ return mentioned by Joel 2 in the O.T. and Jesus in the Olivet Discourse, Matthew 24. Also Isaiah 34:4.

“And I will show wonders in the heavens and on the earth, blood, fire, and columns of smoke. The sun shall be turned to darkness, and the moon to blood, before the great and awesome day of the Lord comes.” Joel 2:30-31

“Immediately after the tribulation of those days the sun will be darkened, and the moon will not give its light, and the stars will fall from heaven, and the powers of the heavens will be shaken. Then will appear in heaven the sign of the Son of Man, and then all the tribes of the earth will mourn, and they will see the Son of Man coming on the clouds of heaven with power and great glory.” Matthew 24:29-30

“When he opened the sixth seal, I looked, and behold, there was a great earthquake, and the sun became black as sackcloth, the full moon became like blood, and the stars of the sky fell to the earth as the fig tree sheds its winter fruit when shaken by a gale. The sky vanished like a scroll that is being rolled up, and every mountain and island was removed from its place. Then the kings of the earth and the great ones and the generals and the rich and the powerful, and everyone, slave and free, hid themselves in the caves and among the rocks of the mountains, calling to the mountains and rocks, “Fall on us and hide us from the face of him who is seated on the throne, and from the wrath of the Lamb, for the great day of their wrath has come, and who can stand?” Revelation 6:12-17
