God wants our conscience to be certain and sure that it is pleasing to Him. This cannot be done if the conscience is led by its own feelings, but only if it relies on the Word of God.
Martin LutherGrace remits sin, and peace quiets the conscience. Sin and conscience torment us, but Christ has overcome these fiends now and forever.
Martin LutherA Christian is a perfectly free lord of all, subject to none. A Christian is a perfectly dutiful servant of all, subject of all, subject to all.
Martin Luther
