2 Thessalonians 2:11

11 For this reason God sends them a strong delusion so that they will believe what is false,

2 Thessalonians 2:11 In-Context

9 The coming [of the lawless one] is based on Satan's working, with all kinds of false miracles, signs, and wonders,
10 and with every unrighteous deception among those who are perishing. [They perish] because they did not accept the love of the truth in order to be saved.
11 For this reason God sends them a strong delusion so that they will believe what is false,
12 so that all will be condemned-those who did not believe the truth but enjoyed unrighteousness.
13 But we must always thank God for you, brothers loved by the Lord, because from the beginning God has chosen you for salvation through sanctification by the Spirit and through belief in the truth.
