If he have faith, the believer cannot be restrained. He betrays himself. He breaks out. He confesses and teaches this gospel to the people at the risk of life itself.
Martin LutherTake a look at your own heart, and you will soon find out what has stuck to it and where your treasure is. It is easy to determine whether hearing the Word of God, living according to it, and achieving such a life gives you as much enjoyment and calls forth as much diligence from you as does accumulating and saving money and property.
Martin LutherMerit 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 LutherWhen some say that good works are forbidden when we preach faith alone, it is as if I said to a sick man: "If you had health, you would have the use of all your limbs; but without health, the works of all your limbs are nothing"; and he wanted to infer that I had forbidden the works of all his limbs.
