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 LutherWe must beat the Gospel into peoples' heads incessantly because it's the one thing we're prone to forget.
Martin Luther
