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).
