There is much I could say about you, and much to judge. But the one who sent me is true, and what I have heard from him — that is what I tell the world.”
In context
24That is why I told you that you will die in your sins: if you do not believe that I am he, you will die in your sins.” 25“Who are you?” they asked. Jesus said to them, “What I have been telling you from the beginning. 26There is much I could say about you, and much to judge. But the one who sent me is true, and what I have heard from him — that is what I tell the world.” 27They did not understand that he was speaking to them about the Father. 28So 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; I say only what the Father has taught me.
