He will exalt himself and defy everything that people call god and every object of worship. He will even sit in the temple of God, claiming that he himself is God.

Then the man of lawlessness will be revealed, but the Lord Jesus will slay him with the breath of his mouth and destroy him by the splendor of his coming.
