13 The Pharisees replied, "You are making those claims about yourself! Such testimony is not valid." 14 Jesus told them, "These claims are valid even though I make them about myself. For I know where I came from and where I am going, but you don't know this about me.
Matthew Henry's Commentary on John 8:13-14
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.
