John 5:31

If I . . . witness of myself--standing alone, and setting up any separate interest.

In these verses our Lord Jesus proves and confirms the commission he had produced, and makes it out that he was sent of God to be the Messiah. I. He sets aside his own testimony of himself (Joh 5:31): "If I bear witness of myself, though it is infallibly true (Joh 8:14), yet, according to the common rule of judgment among men, you will not admit it as legal proof, nor allow it to be given in evidence." Now, 1. This reflects reproach upon the sons of men, and their veracity and integrity. Surely we may say deliberately, what David said in haste, All men are liars, else it would never have been such a received maxim that a man's testimony of himself is suspicious, and not to be relied on; it is a sign that self-love is stronger than the love of truth. And yet, 2.

II. He produces other witnesses that bear testimony to him that he was sent of God. 1. The Father himself bore testimony to him (Joh 5:32): There is another that beareth witness. I take this to be meant of God the Father, for Christ mentions his testimony with his own (Joh 8:18): I bear witness of myself, and the Father beareth witness of me. Observe, (1.) The seal which the Father put to his commission: He beareth witness of me, not only has done so by a voice from heaven, but still does so by the tokens of his presence with me. See who they are to whom God will bear witness. [1.] Those whom he sends and employs; where he gives commissions he give cr…

5:31-40 God’s law requires more than one witness in a trial (Deut 17:6), so Jesus acknowledged that his own testimony was admissible only when confirmed by other witnesses. Thus, he introduced a series of witnesses for his defense.
