Christ now further says:
“He shall bear witness of me.”
 That is, if he is in the heart he speaks through you, and assures and confirms you in the belief that the Gospel is true. Then, as a result, the confession of the Gospel springs forth. What, then, is the Gospel? It is a witness concerning Christ, that he is God’s Son, the Saviour, and beside him there is none other.
He that believeth and is baptized shall be saved; but he that believeth not shall be damned.
”…there is still one more thing here, that Christ says: “He that believeth and is baptized shall be saved.” Here you might say: I perceive, then, that baptism is also required. To be sure it is, but baptism is not a work that we do. It is to be coupled, however, with faith, because God would not have faith to be hidden in the heart, but would have it burst forth and manifest itself to the world.
