He had a wonderful quote that I thought I would share with you all on this principle. It certainly is a beneficial reminder for us Christians that we are freed from the law, and should not be adding a new law in its place:
"We have sinned. And we still fall short. May God grant us the grace to stop playing games with Him. May He grant us the grace to stop trying to impress Him with our behavior and all of our religious practices. May He grant us the grace to stop trying to hide our sins from Him, like He doesn't know. May God grant us the grace to pour contempt on all of our pride, and embrace the Cross as the only root to His loving presence even today."
Listen to the whole message, "We Didn't Pay to Get It (Rom 3:21-31)", here.
