Do as you please, because you are always forgiven? No.
We Lutherans are subject to a special temptation. We have been so much assured that our standing with God is based entirely on God’s free and undeserved love and not on any action of ours that the devil is right there to suggest: “Well, if it not based on any action of yours, your actions don’t matter. You have a nice cushion to rest on there. You have complete forgiveness in Christ. So do as you please. You are always forgiven.” There is no more hideous mockery of Christ and Calvary than that. Christ died in our place so we may not be condemned and punished for our sins. He takes all that for us so we may be forgiven and may know the living God as a God who graciously involves Himself with us and we with Him. Are we, then, to make of this the basis for a life that contradicts that we are involved with Him? — Dr. Norman Nagel, Selected Sermons, p. 348. HT: Weedon.
