2nd Thessalonians Chapter 2 part 1 The Apostasy and the Man of Sin

Before the Return of Christ, two events must first take place:
1) The falling away, which in Greek means "apostasy" or departing from the faith. This has been happening throughout all church history, but in these last days, it will become, and is becoming, greater.
2) The "man of sin" has to be revealed. This man is often referred to as the Antichrist, the leader of the world’s final empire.
