From Luther’s meal chats-
Master Philip examined a student in Anthony Lauterbach’s home. He was a schoolmaster in Stargard, and when he answered thoughtlessly Philip said, “Do not answer so abruptly and burst out so heedlessly, for there are more things we do not know than there are things we know.”
Luther remarked in connection with this, “Jonas once claimed that he knew everything in the Holy Scriptures and was angry at me because I didn’t let this claim pass unnoticed. But I know there are many things I don’t know. I have preached for twenty-five years and still don’t understand the verse, ‘He who through faith is righteous shall live’ [Rom. 1:17].”
