Ok, God said that the end could be at any hour. But b4 the end of the world, doesnt Anti Christ come, and lives as a normal person till hes 28/30 or w/e, and then say he is Christ for 3 years? to sum it up..
"He causes all, both small and great, rich and poor, free and slave, to recieve a mark on their right hand or on their foreheads. and that no one may buy or sell except one who has the mark or or the name of the beast or the number of his name. Here is wisdom, Let him who has understanding calculae the number of the beast, for it is the number of a man: His number is 666."
So this is a wierd question, but wouldnt we know this is the end of world, that it is near, since he comes for 3 years and does- ( Revelation 13:16-18 )??
