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 LutherI frankly confess that even if it were possible I should not wish to have free choice given to me, or to have anything left in my own hands by which I might strive for salvation.
Martin LutherWhat is it to serve God and to do His will? Nothing else than to show mercy to our neighbor. For it is our own neighbor who needs our service; God in heaven needs it not.
Martin Luther
