Authoritative Teaching, Authoritative Action

Jesus is a great moral teacher. He was received as such right from the beginning of his ministry and he has been ever since. And yet, while that is true, it is woefully not enough. Mark tells us a couple times how people were astonished at Jesus teaching but in-between those he heals a man with an unclean spirit. He isn't just a great teacher, he is the one who has power over Satan, sin and death. So what do we do with Jesus? is he a liar, a lunatic, a legend or the Lord of all?
