When God creates faith in a man, that is as great a work as if He created heaven and earth all over again.
Martin LutherThe first care of every Christian ought to be to lay aside all reliance on works, and strengthen his faith alone more and more, and by it grow in the knowledge, not of works, but of Christ Jesus, who has suffered and risen again for him.
Martin LutherHere is the truly Christian life, here is faith really working by love, when a man applies himself with joy and love to the works of that freest servitude in which he serves others voluntarily and for nought, himself abundantly satisfied in the fulness and riches of his own faith.
Martin LutherPeople gave ear to an upstart astrologer who strove to show that the earth revolves, not the heavens or the firmament, the sun and the moon....This fool wishes to reverse the entire science of astronomy; but sacred scripture tells us [Joshua 10:13]that Joshua commanded the sun to stand still, and not the earth.
Martin Luther[The papists] ought to have sympathy with us weak, poor Christians, and not condemn us or make fun of us because we are learning so childishly to toddle along the benches, nay, to creep in the mire, and cannot skip and dance, on such light feet and legs, over and outside of God's commandments, as they do, the strong heroes and giants ... God forbid that we should!
Martin Luther
