Christ is coming in the future. How do we know this? Because He is coming after the abomination of desolation:
2 Thessalonians 2:3-4
3 Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition;
4 Who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God.
For that to happen, the third temple must be built. Because the Jews have been regathered by God back to Israel, the third temple can now be built paving the way for the fulfillment of this prophecy.
These are the current events of end times prophecy, and Israel and Jerusalem are central in understanding end times events. The prophetic significance of Israel becoming a nation again cannot be overstated. The events simply cannot occur if Israel were not to be a nation in the end times. God of course engineered these events which tend to convince me that major fulfillment of end times prophecy could potentially occur. We may be the generation described in 2 Timothy 3:1-5
3 This know also, that in the last days perilous times shall come.
2 For men shall be lovers of their own selves, covetous, boasters, proud, blasphemers, disobedient to parents, unthankful, unholy,
3 Without natural affection, trucebreakers, false accusers, incontinent, fierce, despisers of those that are good,
4 Traitors, heady, highminded, lovers of pleasures more than lovers of God;
5 Having a form of godliness, but denying the power thereof: from such turn away.
The Antichrist has not yet appeared on the world stage but he will arrive one day and probably during a moment of world crisis. He solves a problem, perhaps bringing peace to the middle east. This is of course a false peace which deceives and deludes the world into trusting this man.
He will also have a man on his side who can do miracles:
Revelation 13:11-17
11 And I beheld another beast coming up out of the earth; and he had two horns like a lamb, and he spake as a dragon.
12 And he exerciseth all the power of the first beast before him, and causeth the earth and them which dwell therein to worship the first beast, whose deadly wound was healed.
13 And he doeth great wonders, so that he maketh fire come down from heaven on the earth in the sight of men,
14 And deceiveth them that dwell on the earth by the means of those miracles which he had power to do in the sight of the beast; saying to them that dwell on the earth, that they should make an image to the beast, which had the wound by a sword, and did live.
15 And he had power to give life unto the image of the beast, that the image of the beast should both speak, and cause that as many as would not worship the image of the beast should be killed.
16 And he causeth all, both small and great, rich and poor, free and bond, to receive a mark in their right hand, or in their foreheads:
17 And that no man might buy or sell, save he that had the mark, or the name of the beast, or the number of his name.
This man is called the false prophet. A literal miracle worker who will deceive the whole Earth into worshiping the Antichrist. He will also institute control over the financial system of the world by forcing all human beings to take the mark of the beast.
This is all yet in the future. Biblical prophecy is coming true before our eyes because these are the last days. We are in the last part of the last days, I believe, and we may live to see the coming of our Lord Jesus Christ.
