John 8:15-19

Ye judge after the flesh; I judge no man.

And yet if I judge, my judgment is true: for I am not alone, but I and the Father that sent me.

It is also written in your law, that the testimony of two men is true.

I am one that bear witness of myself, and the Father that sent me beareth witness of me.

Then said they unto him, Where is thy Father? Jesus answered, Ye neither know me, nor my Father: if ye had known me, ye should have known my Father also.
