 He is the exalter of himself. Again, in 2 Thessalonians, Paul uses a participle. He is the one who exalts himself, and that same verb is used twice in 2 Corinthians 12, where it says, exalted above measure. He exalts himself, and he opposes all other form of religion. All that is called God, all that is worshiped, all deities, all shrines, all images, all elders, everything takes a second place to him.
