jn 5:31-36
"If I testify on my own behalf, my testimony cannot be verified. But there is another who testifies on my behalf, and I know that the testimony he gives on my behalf is true. You sent emissaries to John, and he testified to the truth. I do not accept testimony from a human being, but I say this so that you may be saved. He was a burning and shining lamp, and for a while you were content to rejoice in his light. But I have testimony greater than John's. The works that the Father gave me to accomplish, these works that I perform testify on my behalf that the Father has sent me.
