In 2 Thessalonians 2:1-13, Paul steadies shaken believers facing false claims that the day of the Lord had already come. He outlines the clear sequence: a great rebellion, the revealing of the man of lawlessness who exalts himself in God’s temple, and the removal of the restrainer—possibly the Holy Spirit or a powerful angel. Satan empowers this figure with deceptive signs, yet Christ destroys him at His return. Believers, chosen for salvation, stand firm in truth amid growing lawlessness.
