2 Thessalonians 2:3-6

3Let no one deceive you in any way. For that day will not arrive until the rebellion comes and the man of lawlessness is revealed, the son of destruction.

4He opposes and exalts himself above every so-called god or object of worship, and as a result he takes his seat in God’s temple, displaying himself as God.

5Surely you recall that I used to tell you these things while I was still with you.

6And so you know what holds him back, so that he will be revealed in his own time.
