Why do we seek His image, we have been given His teachings. I don't believe and image from man, I believe the teachings of God. My image of Christ isn't close to this, it is the image of God. I can't describe it, I can't paint it, I can't draw it, and I wish I could. But, I belive in it, I know what it looks like.
We don't! In His divine majesty, He gave it to us. We don't need His image to believe in Him. Perhaps He recognized the human weakness that desires to keep a picture of a wife, husband and/or children on our desk at the office, and bequeathed this gift to His children.
