John 5:30-34

I can of mine own self do nothing: as I hear, I judge: and my judgment is just; because I seek not mine own will, but the will of the Father which hath sent me.

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.

Ye sent unto John, and he bare witness unto the truth.

But I receive not testimony from man: but these things I say, that ye might be saved.
