Look at all the opinions that people held about Him. In Matthew 16 Jesus asks Peter, Who do men say that I am? His answer is, Some say You are John the Baptist. Others say You are Jeremiah, or one of the prophets. There was much confusion regarding His identity!
If He cannot be clearly identified, how can He possibly be worshipped? How can people possibly say that they see Him - that is, in the sense of comprehending or understanding that He is an absolutely vital part of our lives? For you and me, He is so vital! He is in us, and He is interested in every aspect of our lives.
