What does John 8:51-55 mean?

51 Verily, verily, I say unto you, If a man keep my saying, he shall never see death. 52 Then said the Jews unto him, Now we know that thou hast a devil. Abraham is dead, and the prophets; and thou sayest, If a man keep my saying, he shall never taste of death. 53 Art thou greater than our father Abraham, which is dead? and the prophets are dead: whom makest thou thyself? 54 Jesus answered, If I honour myself, my honour is nothing: it is my Father that honoureth me; of whom ye say, that he is your God: 55 Yet ye have not known him; but I know him: and if I should say, I know him not, I shall be a liar like unto you: but I know him, and keep his saying. (John 8:51-55 KJV)

William Burkitt’s Commentary

Observe here, 1. The blessed fruit and effect of observing our Saviour’s doctrine: He that keeps my sayings shall never see death; that is, shall be secured from eternal misery, and enjoy eternal life.

Observe, 2. How the Jews misunderstood our Saviour’s words. He that keeps my saying shall never see death; as if he meant a freedom from temporal death, and hereupon they looked upon him as beside himself, to promise a privilige which neither Abraham, nor the prophets did ever enjoy. Whereas it was not exemption from temporal death, but freedom from eternal destruction, which our Saviour promised to them that keep his saying.

Hence learn, That the misunderstanding of Christ’s doctrine, and taking it in a carnal sense, has given occasion for the many cavils and objections made against it.

Observe, 3. How Christ clears himself of all ambition in this matter, and shews that he did not make this promise of delivering his followers from death vain-gloriously, but that God, whom they called their father had honoured him with power, to make good whatever he had promised to them that keep his saying.

Learn hence, That as Christ entirely sought his Father’s glory; so the Father conferred all honour and glory upon Christ as Mediator: thereby testifying, how infinitely pleased he was with the redemption of mankind performed by him. If I honour myself, my honour is nothing; it is my Father that honoureth me.
