You must have missed my answer to Freodin. The question is do I represent my own opinions or do I represent the Bible and the truth of God? Even Jesus did not represent Himself, He represented the Father.
John 8:28
Then Jesus said to them, "When you lift up the Son of Man, then you will know that I am He, and that I do nothing of Myself; but as My Father taught Me, I speak these things.
How could it be any more clear than this? Jesus did nothing of Himself, he would only speak the things that He learned from the Father.
John 14:10
Do you not believe that I am in the Father, and the Father in Me? The words that I speak to you I do not speak on My own authority; but the Father who dwells in Me does the works.
It was though His works that you could know that Jesus represented God. He want about teaching, preaching and healing. So the miracles and the healing gave evidence that God was with Him.
