I have many things to say and to judge of you. — The order of thought here is not certain, and will depend, in part, upon the interpretation we give to the previous verse. These words seem to arise from their judgment of Him as expressed in their scornful question, “Who art thou?” He has, indeed, immediately before (John 8:23), spoken of them. He is about in this discourse to do so again. There are present to His mind now many things to say of them, and these, if said, would be in words of condemnation; but He refrains. There is present to His mind also the great work He had to do — to speak to the world the eternal truth of God.
But he that sent me is true. — The words express a marked contrast to the words and thoughts with which He would come in contact, if He said and judged concerning them. They refer to the calm repose of the divine life in heaven, as contrasted with the misunderstandings and objections with which the manifestation of that life on earth had been encompassed. He turns from them to the thought of Him who sent Him, and who is true.
And I speak to the world those things which I have heard of him. — Better, I speak unto the world the things which I heard from Him. It is the truth brought into and announced in the world, and which was heard during the pre-incarnate life with the Father. (Comp. John 8:28; John 8:38.)
