Adam transgressed God's command and thereby plunged himself and all his descendants into eternal destruction; but, nevertheless, by true repentance he returned again to God.
David committed murder and adultery and, nonetheless, returned to God in true repentance.
Manasseh filled Jerusalem with innocent blood yet, through genuine repentance, he was released from his sins.
Peter denied Christ yet was still received again into grace because he had done true repentance.
Many such examples are given in the divine writings of the Old and New Testament for the comforting of the repentant—because that which the Lord God did for them He will fulfill for us as well.—Blessed Johann Gerhard, Postilla II, p. 204.
