The New Testament uses the Old Testament heavily, as a way of legitimizing Jesus' role as the Messiah and the last prophet. We look at Moses' statement that a prophet from among the Israelites will rise up - and that we should listen to him. We see that passage echoed in both Acts and the Gospel of Matthew. I take a humorous look at a sister at my Catholic grammar school who caught me not paying attention in class, and yelled at me to listen to her. But the sober truth is that there is only one person to whom we must ALWAYS listen.
