I think I used the wrong wording when I said Jesus gave up His right to use His Supernatural power while on earth. What I really meant was, He set them aside for a time so He could be fully human. I believe Jesus showed us how to live on this earth as human beings the way God intended us to be.
These posts do help to clarify for me this issue. If Jesus was using His own supernaturlal powers to heal, to cast out demons,etc. He would not be fully Man. I think that is what I am getting from your post. If not, please clarify.
Thanks so much!
