And yet if I judge, my judgment is true. — Though judgment was not the object of His mission, it was, as He had taught in John 3:19 (see Note there) the result of the manifestation of the Light. But in the cases in which the result followed, the judgment was not according to the flesh, but was in accord with the essential truth. The better reading here is, probably, the deeper word for ideally true, which we have had before. (Comp. Note on John 1:9.)
For I am not alone, but I and the Father that sent me. — Comp. Note on John 5:30. Here, as there. He identifies every act of judgment with the eternal and unchangeable truth of the Father.
