Mark Hasenmyer spoke about The Falling Away of the followers of Christ.
2Thessalonians 2:3-4 Let no man deceive you by any means: for that day (the coming of our Lord Jesus Christ) shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition; Who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God.
