John 5:31

John 5:31. If I bear witness concerning myself, my witness is not true. The word ‘I' is emphatic, ‘if it is I that bear witness.' The words plainly mean ‘I and I alone,' for no one is discredited because he testifies to himself, although he is not credited if no other witness appears on his behalf. The Jews may have understood Jesus to mean: If I have no other witness to testify concerning me, my testimony cannot claim to be received. But there is more in His words. In the consciousness of oneness with the Father, He would say that if it were possible that His own witness should stand alone, unaccompanied by that of the Father, it would be self-convicted, would not be true: He, in making the assertion, would be false, for He is one with the Father, and His statement, as that of one who was false, would be false also. He must therefore show that the witness He bore to Himself was really borne to Him by the Father: the Father's witness even the Jews will acknowledge to be true. To this, therefore, He proceeds.
