“Please forgive my sin once more and make an appeal to the Lord your God, so that he will just take this death away from me.”
The second time forgiveness of sin is mentioned in the Bible is on the lips of Pharaoh, after the eight plague. Even pagans had an understanding of sin and its consequences.
Our repentance should desire more than avoiding the death brought by sin. It should look toward the holy nature of God and be motived by desire to enter his presence.
