(16) 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.

Verse 16. - And yet (the καὶ δέ, equivalent to atque etiam - so Meyer, Luthardt, etc. - "This is the condemnation, that light is come into the world, and men love darkness rather than light;" "The light shineth, and the darkness comprehendeth it not." The prince of this world is judged by the simple uplifting of the Son of God; and so, though he did not come to judge or condemn, yet judgments did, by the very necessity of his nature, proceed from him) even if I judge - if by the mere contact of his purity and love and healing power with those who will not come to him for life, judgment is pronounced - my judgment is true; i.e. trustworthy. The reading of Tischendorf, ἀληθινή, would mean that it "answers to the fundamental conception of a judgment." This thought would make the apparent paradox of the sentence more difficult to resolve. Because I am net alone, but (or, because, on the other hand) I and the Father who sent me, together deliver this judgment; i.e. it does not rest on my mere human consciousness, on what you who judge after the flesh might suppose it would rest, but on the eternal decisions of him who gave me my commission. The Father is in me and with me. I think the Father's thoughts and do the Father's will. Christ's testimony concerning himself, his implicit judgments on human nature, his indirect condemnation of the whole crowd, by his gracious refusal to condemn the sinful woman to immediate doom, all issue forth with the sign manual of Almighty God, with whom and in whom he dwells as the only begotten Son.

8:12-16 Christ is the Light of the world. God is light, and Christ is the image of the invisible God. One sun enlightens the whole world; so does one Christ, and there needs no more. What a dark dungeon would the world be without the sun! So would it be without Jesus, by whom light came into the world. Those who follow Christ shall not walk in darkness. They shall not be left without the truths which are necessary to keep them from destroying error, and the directions in the way of duty, necessary to keep them from condemning sin.And yet if I judge, my judgment is true,.... Because he saw not as man did, nor looked unto, and judged according to the outward appearance of things; but looked into the heart, and knew what was in it, being the searcher and trier of it; to whom all things are naked and open, and therefore cannot be deceived or imposed upon; his judgment must be sure and infallible:

for I am not alone, but I and the Father that sent me; he was not separate from the Father, or at a distance from him, when he was here on earth; he was in his bosom, and in heaven, as the Son of God, when as the son of man, he was below; nor was he alone in his testimony and judgment, the Father joined with him therein: and which is a further proof of the truth of his testimony, and the certainty of his judgment.
