Self delusion is the gift for wicked and hypocrites who have hardened their hearts, they don’t live by faith nor do they have a spirit of Jesus Christ. From outside they act as a great Godly people but inside they are morally impure. Because of their wickedness they did not hear to Gods word he gave self delusion in their hearts.
A self delusion person always thinks that he is rich in spiritual knowledge, he is better than others; he often thinks that God will not punish for his sins nor they will be judged by Jesus Christ. He thinks his own ways are always right and pure, their ways will get into heaven and they will have peace while they are still sinning. They pretend that the other party has done no wrong, but to accept our common humanity and to recognize that we are all sinners, that we have all done wrong and fall short of God’s calling. The self delusion person justifies himself before other man and he Rejects the righteousness of God. God doesn’t have any interest in such people and because of their wickedness they bring the sudden destruction into their life.
