God Said It …

41So the Jews grumbled about him, because he said, “I am the bread that came down from heaven.” 42They said, “Is not this Jesus, the son of Joseph, whose father and mother we know? How does he now say, ‘I have come down from heaven’?” (John 6:41-42)

Whoever wants to be a Christian and apprehend the articles of the Christian faith must not consult reason and mind how a doctrine sounds and whether it is consistent with reason. He must say forthwith: “I do not care whether it agrees with reason or not. All I must know is whether or not it is supported by God’s Word. This I ask: Did God say it? That decides it for me.”
Luther’s Works, v. 23, 78-79
