Compared with the miracle of the forgiveness of sin, the experience of sanctification is small. Sanctification is simply the wonderful expression or evidence of the forgiveness of sins in a human life. But the thing that awakens the deepest fountain of gratitude in a human being is that God has forgiven his sin. Paul never got away from this. Once you realize all that it cost God to forgive you, you will be held as in a vise, constrained by the love of God.
