Merit is a work for the sake of which Christ gives rewards. But no such work is to be found, for Christ gives by promise. Just as if a prince should say to me, "Come to me in my castle, and I will give you a hundred florins." I do a work, certainly, in going to the castle, but the gift is not given me as the reward of my work in going, but because the prince promised it to me.
Martin LutherThere is on earth among all dangers, no more dangerous thing than a richly endowed and adroid reason, especially if she enters into spiritual matters which concern the soul and God. For it is more possible to teach an ass to read than to blind such a reason and lead it right; for reason must be deluded, blinded, and destroyed.
Martin LutherOriginal sin is in us like our beard. We are shaved today and look clean; tomorrow our beard has grown again, nor does it cease growing while we remain on earth. In like manner original sin cannot be extirpated from us; it springs up in us as long as we live.
Martin LutherTo have peace and love in marriage is a gift which is next to the knowledge of the Gospel.
Martin Luther
