Because of the weakness of its infirmity, the human race was unable to restrain itself from sin and had become subject to the death of hell. God was moved by the righteousness of his mercy, by which he always comes to the aid of the human race, and through Christ he provided a way by which he could reward those who were without hope. By forgiving their sins he released them from the law which had held them subject. Restored and made whole again by the help of God, they could reject the sins by which they had previously been held down.
