Let no man deceive you by any means for that day 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. 11 Thessalonians 2 : 3,4
