“If you, LORD, should mark iniquities, O lord, who shall stand?
But there is forgiveness with you, that you may be feared.”
God’s power to forgive sin is a reason to fear him, just as David said. For if God can forgive, He can also choose not to, and the salvation of your soul depends upon your being forgiven.
Jesus was right, as always, when he warned his disciples, “Don’t be afraid of those who kill the body but can’t kill the soul; rather, fear Him who is able to destroy both soul and body in Gehenna.” (Mt. 10:28). In other words, “Fear Him who is able to forgive you.”
