For we are not fighting against flesh-and-blood enemies, but against evil rulers and authorities of the unseen world, against mighty powers in this dark world, and against evil spirits in the heavenly places.
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.
The Lord isn’t really being slow about his promise, as some people think. No, he is being patient for your sake. He does not want anyone to be destroyed, but wants everyone to repent.
