For since by a man came death, by a man also came the resurrection of the dead. For as in Adam all die, so also in Christ all will be made alive. (1 Corinthians 15:21-22)

Therefore, just as through one man sin entered into the world, and death through sin, and so death spread to all men, because all sinned… (Romans 5:12)

And this includes Raptured believers, since it says ALL men. Even though our spiritual bodies will live forever, our corruptible "earthly tent" will DIE. It's similar to a snake shedding his skin, in order to get his new revitalized skin. And since up to that point in time, Elijah and Enoch will be the only ones to be removed from earth without their bodies dying, I absolutely believe it will be those two who are the Two Witnesses.

I agree with Pastor Riley that it can't be Moses, because Scripture plainly states that Moses died and was buried, and is STILL dead, awaiting resurrection.

Be blessed!
