God Does Not Allow You To Go On Rejecting Him Forever Without Penalty

2 Thessalonians 2:10-12 AMP
10 And by unlimited seduction to evil and with all wicked deception for those who are perishing (going to perdition)(perdition – a state of final spiritual ruin; loss of the soul; damnation) because they did not welcome the Truth but refused to love it that they might be saved. (What you have just done by rejecting Christ)
11 Therefore God sends upon them a misleading influence, a working of error and a strong delusion to make them believe what is false,
12 In order that all may be judged and condemned who did not believe in [who refused to adhere to, trust in, and rely on] the Truth, but [instead] took pleasure in unrighteousness. (Plan B – doing things your way instead of God’s.)
