15 You judge according to the flesh; I judge no one. 16 Yet even if I do judge, my judgment is true, for it is not I alone who judge, but I and the Father[1] who sent me. 17 In your Law it is written that the testimony of two people is true. 18 I am the one who bears witness about myself, and the Father who sent me bears witness about me."
Matthew Henry's Commentary on John 8:15-18
Commentary on John 8:12-16
(Read John 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.
Commentary on John 8:17-20
(Read John 8:17-20)
If we knew Christ better, we should know the Father better. Those become vain in their imaginations concerning God, who will not learn of Christ. Those who know not his glory and grace, know not the Father that sent him. The time of our departure out of the world, depends upon God. Our enemies cannot hasten it any sooner, nor can our friends delay it any longer, than the time appointed of the Father. Every true believer can look up and say with pleasure, My times are in thy hand, and better there than in my own. To all God's purposes there is a time.
