2 Thessalonians 2:11-13

Because of this, God sends them a powerful delusion that leads them to believe what is false. So then all who found their pleasure in unrighteousness and did not believe the truth will be judged. We always have to thank God for you, brothers and sisters, for you are dearly loved by the Lord. He proved it by choosing you from the beginning for salvation through the Spirit, who set you apart for holiness, and through your belief in the truth.
