1) Self-delusion is a characteristic of the wicked where prosperity leads them to believe they will never face adversity and their ways are right.
2) The obstinately wicked are often given over to their own hearts' lusts and deceitful beliefs that they are pure, better than others, and can have peace in sin.
3) Those who are self-deluded hold beliefs like gifts or privileges entitle them to heaven and that God will not punish their sins, preserving such delusions until the end when the fatal consequences are realized.
