No man was ever condemned for his sin. The condemnation always falls because of a refusal to turn from it. The seal on the vault of damnation bears this imprint—“I will not turn.” The sealing of damnation is complete when the wax on that seal hardens, just like the heart it represents. God is angry with the wicked every day “if he turn not” (Ps. 7:11-12). This means that the damning sin, the only damning sin, is stubbornness.
