In 1863 President Lincoln implemented three days of humiliation, fasting and prayer with this declaration: “It is the duty of nations as well as men to own their own dependence upon the overruling power of God, to confess their sins and transgressions in humble sorrow yet with assured hope that genuine repentance will lead to mercy and pardon, and to recognise the sublime truth, announced in the Holy Scriptures and proven by all history: that those nations only are blessed whose God is the Lord.”
God does bring calamities and disasters such as firestorms, earthquakes and tornadoes for His purposes. It is invariably to make people realise they are not in control of circumstances in the world He created and maintains. Importantly, it is also to to get His own people to pray. Moreover, God tells us in advance in His Word that in the “last days” before Jesus returns that these disasters will increase in frequency. Just one of many signs, God has given us, to show we are in the last days before Jesus returns to rule and reign from Jerusalem.
“When I shut up heaven and there is no rain, or command the locusts to devour the land, or send pestilence among My people, if My people who are called by My name will humble themselves, and pray and seek My face, and turn from their wicked ways, then I will hear from heaven, and will forgive their sin and heal their land.” 2 Chronicles 7:13-14
“And there will be signs in the sun, in the moon, and in the stars; and on the earth distress of nations, with perplexity, the sea and the waves roaring; men’s hearts failing them from fear and the expectation of those things which are coming on the earth, for the powers of the heavens will be shaken.” Luke 21:25-26
“See that you do not refuse Him (GOD) who speaks. For if they did not escape who refused Him (JESUS) who spoke on earth, much more shall we not escape if we turn away from Him who speaks from heaven, whose voice then shook the earth; but now He has promised, saying, “Yet once more I shake not only the earth, but also heaven.” Now this, “Yet once more,” indicates the removal of those things that are being shaken, as of things that are made, that the things which cannot be shaken may remain. Therefore, since we are receiving a kingdom which cannot be shaken, let us have grace, by which we may serve God acceptably with reverence and godly fear. For our God is a consuming fire.” Hebrews 12:25-28
