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 LutherFor all works and things, which are either commanded or forbidden by God and thus have been instituted by the supreme Majesty, are 'musts.' Nevertheless, no one should be dragged to them or away from them by the hair, for I can drive no man to heaven or beat him into it with a club.
Martin LutherRiches are the pettiest and least worthy gifts which God can give a man. What are they to God's Word, to bodily gifts, such as beauty and health; or to the gifts of the mind, such as understanding, skill, wisdom! Yet men toil for them day and night, and take no rest. Therefore God commonly gives riches to foolish people to whom he gives nothing else.
Martin LutherAt night always carry in your heart something from Holy Scriptures to bed with you, meditate upon it like a ruminant animal, and go softly to sleep; but this must not be too much, rather a little that may be well pondered and understood, that you may find a remnant of it in your mind when you rise in the morning.
Martin Luther
