“So they said to him, “Who are you?” Jesus said to them, “Just what I have been telling you from the beginning.”
(John 8:25)

I love Martin Luther’s comments on this passage. “They…desire to know who he is, and not to regard what he says, while He desires them to first listen, and then they will know who he is. So listen and allow the Word to make a beginning; then the knowing will nicely follow. If, however, you do not listen, then you will never know anything. For it is decreed: God will not be seen, known or comprehended except through his Word alone. We are to read his Word, to think and speak about it, and to study it. It is certain that he himself is speaking with us in it.” (What Luther Says; An Anthology)

Now you know who he is! Right!
