If I bear witness of myself, my witness is not true.
There is another that beareth witness of me; and I know that the witness which he witnesseth of me is true.
But I receive not testimony from man: but these things I say, that ye might be saved.
And the Father himself, which hath sent me, hath borne witness of me. Ye have neither heard his voice at any time, nor seen his shape.
If I bear witness of myself, my witness is not true
We have considered how all mortals have a perspective that is subject to bias, how each of us is destined to make flaws in our judgments, and how we believe things that are simply false. Thus, if my testimony comes from my own understanding, then it is not much to rely on. An “Abe Austin original” is not worth much at all. If ever I do manage to say something that is true or wise or edifying, it will be because it came from some other source.
But I receive not testimony from man: but the Father himself, which hath sent me, hath borne witness of me.
As we saw in the first verse, Jesus himself felt that a testimony which emanates only from the self is extremely suspect. If it was only his own claim that he was the Son of God, then that argument wouldn’t hold water. Anyone could say that, and in fact many of the insane have.
But Jesus is not the witness of his own divinity, and he did not ask his disciples to just take his own word for it. It is very significant that his witness of truth came from without himself. It came from the only sure and flawless source: God.
It might seem a bold thing to call out God, Himself, as the witness to the truths you speak, but it is the only testimony that will ever carry weight. It becomes less bold of an idea, though, when we realize we aren’t invoking Him to back up our truths, we are invoking Him to back up His own. If we don’t feel that we can call on Him to stand behind what we’re saying, then maybe what we’re saying isn’t actually from Him, and we should reconsider its validity.
