The plan of salvation teaches me, not merely that I can never do anything to earn, increase, or extend God's favor, or to avoid the justified fury of His wrath, or to wheedle benefits out of Him, but also that I never need to try to do any of these things. God himself has loved me from eternity. He Himself has redeemed me from hell through the cross. He Himself has renewed my heart and brought me to faith. He Himself has now sovereignly committed Himself to complete the transformation of me into Christ's likeness and to set me, faultless and glorified, in His own presence for all eternity. When almighty love has thus totally taken over the task of getting me home to glory, responsive love, fed by gratitude and expressed in thanksgiving, should surface spontaneously as the ruling passion of my life. It will be my wisdom to brood on and mull over the marvelous mercies of God's plan until it does.
