Although we don't know the exact time of Jesus' second coming, we do know that He is coming soon. The signs, that are predicted in the Bible, give evidence of this. The period before the second coming of Christ can be divided into two phases: the first phase is that of global distress and the second phase is the great tribulation.
These are the different signs in the first phase:
a great increase of wars, here and there
an increase of natural disasters, great earthquakes, floods etc.
famines and epidemics
an increase in godlessness: moral decline, more pleasure in evil than in good; people's love will grow cold
watch the nation of Israel and the Jewish people: the Jews were scattered to all the ends of the earth. But the Bible predicts that God will bring His people back to their own country in the last days . The city of Jerusalem also plays an important role in these last days. Jerusalem was ruled by heathens (non-Jews) for 2000 years. But in 1967 Jerusalem was given back to the Jews and she is now governed by the Jews.
In the second phase, the great tribulation, a dangerous leader will reveal himself. The Bible says in 2 Thessalonians 2:3 and 9-10: "Don't let anyone deceive you in any way, for that day will not come until the rebellion occurs and the man of lawlessness is revealed, the man doomed to destructionÖ The coming of the lawless one will be in accordance with the work of Satan displayed in all kinds of counterfeit miracles, signs and wonders, and in every sort of evil that deceives those who are perishing. They perish because they refused to love the truth and so be saved."
The increasing crises and despair in our days fit exactly with the Bible's predictions. According to the Bible this will eventually lead to a worldwide acceptance of a totalitarian world government and a world dictator, whom the Bible calls the antichrist.
If we take a look at e.g. Germany after 1930: a growing economic crisis, an increase of drug use (cocaine) and the flourishing of occult activity. This created a demonic atmosphere that lay at the base of the appointing of a demonic leader: Adolf Hitler.
Even in our days we can see an incredible growth of the occult.
Jesus Christ warned us for deception: "For false Christs and false prophets will appear and perform great signs and miracles to deceive even the elect." (Matthew 24:24)
Following these terrible events of the great tribulation, Jesus will return to earth in power and glory: "For as lightning that comes from the east is visible even in the west, so will be the coming of the Son of Man." (Matthew 24:27)
