John 5:31-38 NIV
“If I testify about myself, my testimony is not true. There is another who testifies in my favor, and I know that his testimony about me is true.
“You have sent to John and he has testified to the truth. Not that I accept human testimony; but I mention it that you may be saved. John was a lamp that burned and gave light, and you chose for a time to enjoy his light.
“I have testimony weightier than that of John. For the works that the Father has given me to finish—the very works that I am doing—testify that the Father has sent me. And the Father who sent me has himself testified concerning me. You have never heard his voice nor seen his form, nor does his word dwell in you, for you do not believe the one he sent.
