2 Thessalonians 2:3-4, 9-12

Don’t be fooled by what they say. For that day will not come until there is a great rebellion against God and the man of lawlessness is revealed—the one who brings destruction. 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.

This man will come to do the work of Satan with counterfeit power and signs and miracles. He will use every kind of evil deception to fool those on their way to destruction, because they refuse to love and accept the truth that would save them. So God will cause them to be greatly deceived, and they will believe these lies. Then they will be condemned for enjoying evil rather than believing the truth.
