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 LutherThe heavenly blessing is to be delivered from the law, sin and death; to be justified and quickened to life: to have peace with God; to have a faithful heart, a joyful conscience, a spiritual consolation; to have the knowledge of Jesus Christ; to have the gift of prophecy, and the revelation of the Scriptures; to have the gift of the Holy Ghost, and to rejoice in God.
Martin Luther
