You know some things about Jesus. I mean, you have a picture in your mind. A visual image, perhaps. A sense of what Jesus was like. How he treated people. His tone of voice, maybe. Certainly, the issues that he cared about most.
As a follower of Jesus that mental picture is vital to you. It probably motivates you. It may inform your decisions about politics, or vocation, or parenting.
Now stop for a moment. Have you ever really thought about where that picture came from? Where did you learn about Jesus?
