I've heard many pre-tib believers say, the churches will be really crowded right after the rapture. This will be greatest time of revival in history. Perhaps this may be true, but I don't
really see this in the Bible, in fact, it mostly says just the opposite.
Rev 2:21; 'I gave her time to repent, and she does not want to repent of her immorality.
Rev 9:20; The rest of mankind, who were not killed by these plagues, did not repent of the works of their hands, so as not to worship demons, and the idols of gold and of silver and of brass and of stone and of wood, which can neither see nor hear nor walk;
Rev 9:21; and they did not repent of their murders nor of their sorceries nor of their immorality nor of their thefts.
Rev 16:9; Men were scorched with fierce heat; and they blasphemed the name of God who has the power over these plagues, and they did not repent so as to give Him glory.
Rev 16:11; and they blasphemed the God of heaven because of their pains and their sores; and they did not repent of their deeds.
It would seem that the vast majority of unbelievers, will remain unsaved during the tribulation. I'm not saying no one will be saved during this time, I just don't see it being a huge revival.
Dan 12:10; "Many will be purged, purified and refined, but the wicked will act wickedly; and none of the wicked will understand, but those who have insight will understand.
Rev 22:11; "Let the one who does wrong, still do wrong; and the one who is filthy, still be filthy; and let the one who is righteous, still practice righteousness; and the one who is holy, still keep himself holy."
