Will there be a Great Revival or Great Apostasy at end time?

Will Jesus come when the Gospel is preached to the whole world?

The end will come (God's Wrath released on Apostates) when the number of the Martyrs is complete, NOT when the gospel goes around the whole earth and reaches Israel. The bible NEVER promise a great revival, he promised a great APOSTASY controlled and widespread by the Whore of Babylon, the Harlot riding on the Scarlett beast, whereby the Kings of the earth will share with her Fornication (Idolatry or False Gospel).

The world will not be saved through seeker friendly, worldly methods of preaching the Gospel. In fact, if a church is adopting these methods to grow, they are likely to attract Tares or False conversion based on wrong understanding of the gospel. If one were to teach the truth, one should expect only a small following who are a reflection of the faithful remnants of Israel.

To expect exponential church growth when teaching the true unadulterated Word of God will only lead one to become dissappointed and burn out, and eventually falling away. Don't work against what God has already told us.

As for Israel, God will take care of his Remnant (of Israel) in the last days. He will graft them in to the New Covenent, IF they heed his word and turn from their wicked ways.

References as below :

When He opened the fifth seal, I saw under the altar the souls of those who had been slain for the word of God and for the testimony which they held. And they cried with a loud voice, saying, “How long, O Lord, holy and true, until You judge and avenge our blood on those who dwell on the earth?” Then a white robe was given to each of them; and it was said to them that they should rest a LITTLE WHILE LONGER, until both the number of their fellow servants and their brethren, who would be killed as they were, was COMPLETED.
Rev 6:9‭-‬11 NKJV

Then I saw another sign in heaven, great and marvelous: seven angels having the seven last plagues, for in them the WRATH OF GOD IS COMPLETED.
Rev 15:1 NKJV

Then one of the seven angels who had the seven bowls came and talked with me, saying to me, “Come, I will show you the judgment of the great harlot who sits on many waters, with whom the kings of the earth committed FORNICATION, and the inhabitants of the earth were made drunk with the wine of her fornication.”
Rev 17:1‭-‬2 NKJV

Now, brethren, concerning the coming of our Lord Jesus Christ and our gathering together to Him, we ask you, not to be soon shaken in mind or troubled, either by spirit or by word or by letter, as if from us, as though the day of Christ had come. Let no one deceive you by any means; for that Day will not come unless the FALLING AWAY COMES FIRST, and the man of sin is revealed, the son of perdition, who opposes and exalts himself above all that is called God or that is worshiped, so that he sits as God in the temple of God, showing himself that he is God.
2Th 2:1‭-‬4 NKJV

God has not cast away His people whom He foreknew. Or do you not know what the Scripture says of Elijah, how he pleads with God against Israel, saying, “ Lord , they have killed Your prophets and torn down Your altars, and I alone am left, and they seek my life”? But what does the divine response say to him? “I have reserved for Myself seven thousand men who have not bowed the knee to Baal.” Even so then, at this present time there is a remnant according to the election of grace. And if by grace, then it is no longer of works; otherwise grace is no longer grace. But if it is of works, it is no longer grace; otherwise work is no longer work.
Ro 11:2‭-‬6 NKJV

And they also, if they do not continue in unbelief, will be grafted in, for God is able to graft them in again. For if you were cut out of the olive tree which is wild by nature, and were grafted contrary to nature into a cultivated olive tree, how much more will these, who are natural branches, be grafted into their own olive tree?
Ro 11:23‭-‬24 NKJV
