But he who sent me is trustworthy, and what I have heard from him I tell the world." 27 They did not understand that he was telling them about his Father. 28 So Jesus said, "When you have lifted up  the Son of Man, then you will know that I am he and that I do nothing on my own but speak just what the Father has taught me.
