15 You decide according to what you can see and touch. I don't make judgments like that. 16 But even if I did, my judgment would be true because I wouldn't make it out of the narrowness of my experience but in the largeness of the One who sent me, the Father. 17 That fulfills the conditions set down in God's Law: that you can count on the testimony of two witnesses. 18 And that is what you have: You have my word and you have the word of the Father who sent 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.
