Salvation is necessarily all of grace.  Man’s fall is so complete, God’s justice so inexorable, heaven so holy, that nothing short of Omnipotent love can lift the sinner, magnify the law which he has mutilated, and make him pure enough to dwell in light.  The thought of saving sinners is God’s, born in the secret places of His great, loving heart.
