Paul is talking about the coming of the Lord and the coming of the man of sin, the son of perdition. The great falling away that Paul talks about will not be REAL men. It will be those that are following along for the loaves and fishes and the miracles, not the ones tarrying in the upper room for the power from high (TRUTH).
As our world stands trembling in fear of current conditions, we as REAL men can unite together and stand for truth not being afraid of the things to come knowing that we're ready for his soon return.
