To Be a Theologian of the Cross

If you want to be a maker of God, come here and listen. He wants to teach you
the art so that you do not err and make an idol but make the true God as he
really is. Not that you are to create his divine nature, for it is and remains
eternally uncreated; rather, you are to make him God for you, so that he might
also be for you a true God, as he is for himself a true God.

The art of doing this is set forth briefly and surely in these words: "Do this
in remebrance of me." Learn to remember him, that is, as has been said, by
preaching, praising, honoring, listening, and giving thanks for the grace
revealed in Christ. If you do that, behold, you are confessing with heart and
mouth, with ears and eyes, with body and soul that you have given nothing to
God, nor are able to, but that you have and receive each and every thing from
him, particularly eternal life and infinite righteousness in Christ. (Admonition
Concerning the Sacrament, LW 38: 107)
