Expositor's Bible Commentary Commentary 2 Thessalonians 2:12

"that they all might be judged who believed not the truth, but had pleasure in unrighteousness." — 2 Thessalonians 2:12 (ASV)

The ultimate consequences for them will be condemnation. Failing to appropriate the truth of the Gospel, they willingly choose wickedness instead; they cannot blame circumstances. Retrospect will show their own wrongly directed personal delight to be the cause of God’s adverse judgment against them (cf. 1:9). What an incentive this powerful passage is for non-Christians to turn to God before the rebellion and delusion arrive!
