2 Thessalonians 2:3-5

2:3 Let 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. 2:4 He 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. 2:5 Surely you recall that I used to tell you these things while I was still with you.
