8:14 Jesus answered and said unto them, {b} Though I bear record of myself, [yet] my record is true: for I know whence I came, and whither I go; but ye cannot tell whence I come, and whither I go.
(b) That which he denied before in Joh 5:31 must be understood as Christ granting their position in a way, for in that place he talked of himself somewhat in line with the opinions of his hearers, who acknowledged nothing in Christ but his humanity, and therefore he was content they should not regard his own witness, unless it were otherwise confirmed. But in this place he stands and affirms Godhead, and praises his Father, who is his witness, and agrees with him.
8:14 My record is true. The Pharisees disputed this. Ordinarily the testimony of a man that he is sent from God is insufficient. He may be deceived or a deceiver. But Jesus could not be deceived, for he knew all things; nor a deceiver, for he was Truth. Besides, he had other testimony (Joh 8:18).
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.
