The sin of Adam had come into all men. Through one man, the Apostle says, sin entered and through sin, death. Thus it has come to all men. Therefore, the justice of Christ must enter into men; and as the old Adam ruined his descendants through sin, so Christ must bring new life to all men through justice. The Apostle stresses this theme when he says: As through the disobedience of one man, many were made sinners, so too, through the obedience of one man, many were made just. And, as sin brought death to the offender, so grace through justice brings birth to life eternal.
