All the images of Jesus are merely an artist's impression of what Christ might have looked like. But that is really beside the point. He is no longer flesh, but a powerful spirit being. In fact he was raised up to now be the exact representation of his father, Jehovah. (Hebrews 1:3). Moreover, Jesus set the example and directed worship to the father. So I pray to the father, Jehovah, in the name of jesus, a he directed. But to picture the 2 most glorious persons in the universe in human terms would be grossly inappropriate.
