This is that mystery which is rich in divine grace unto sinners: wherein by a wonderful exchange, our sins are no longer ours but Christ's; and the righteousness of Christ is not Christ's but ours. He has emptied himself of his righteousness that he might clothe us in it, and fill us with it: and he has taken our evils upon himself that he might deliver us from them.
Martin LutherThe kingdom of God does not consist in talk, but in power, that is, in works and practice. God loves the 'doers of the word' in faith and love, and not the 'mere hearers,' who, like parrots, have learned to utter certain expressions with readiness.
Martin Luther
