John 8:55

"And I keep His saying." Here they might, if at least they had anything to say, have refuted Him, for it was the strongest proof of His having been sent by God. "Your father Abraham rejoiced to see My day, and he saw it, and was glad." Again, He showeth that they were aliens from the race of Abraham, if they grieved at what he rejoiced in. "My day," seems to me to mean the day of the Crucifixion, which Abraham foreshowed typically by the offering of the ram and of Isaac.

"Yet ye have not known Him." Because He desired to show that they not only knew not His Father, but that they knew not God. "But I know Him." "So that to say, 'I know Him,' is not a boast, while to say, 'I know Him not,' would be a falsehood; but ye when ye say that ye know Him, lie; as then ye, when ye say that ye know Him, lie, so also should I, were I to say that I know Him not." "If I honor Myself." Since they said, "Whom makest thou thyself?" He replieth, "If I make (Myself anything,) My honor is nothing. As then I know Him exactly, so ye know Him not." And as in the case of Abraham, He did not take away their whole assertion, but said, "I know that ye are Abraham's seed," so as to make the charge against them heavier; thus here He doth not remove the whole, but what? "Whom ye say." By granting to them their boast of words, He increaseth the force of the accusation against them. How then do ye "not know Him"? "Because ye insult One who saith and doeth everything that He may be glorified, even when that One is sent from Him." This assertion is unsupported by testimony, but what follows serves to establish it. "And I keep His saying." Here they might, if at least they had anything to say, have refuted Him, for it was the strongest proof of His having been sent by God.

For had they known the Father really, they would have reverenced the Son. But they even despise God, who in the Law forbad murder, by their clamours against Christ. Wherefore He says, Ye have not known Him. Having that knowledge by nature; for as I am, so is the Father also; I know Myself, and therefore I know Him. And He gives the proof that He knows Him: And I keep His saying, i. e. His commandments. Some understand, I keep His saying, to mean, I keep the nature of His substance unchanged; for the substance of the Father and the Son is the same, as their nature is the same; and therefore I know the Father. And here has the force of because: I know Him because I keep His saying.

From this it is clear that you do not know Him at all. But I know Him by nature, I have perfect knowledge of Him. For, as I am, so also is the Father. And as I know Myself, so I also know Him. "For …

"And you have not known him": for they were among those of whom it is said in Titus 1: "They profess to know God, but by their deeds they deny him." "But I know him," and this indeed not out of boasting, but for the …

As if to say, Ye call Him your God, after a carnal manner, serving Him for temporal rewards. Ye have not known Him, as He should be known; ye are not able to serve Him spiritually.

Then he shows both these things, that is, the error of the Jews, and his own truth, when he says, but you have not known him. He shows these in two ways: first, by pointing out the ignorance of the Jews; secondly, his own knowledge …

Yet ye have not known him,....

There is one who demands it, and he also judges. I tell you the solemn truth, if anyone obeys my teaching, he will never see death." Then the Jewish people who had been listening to him responded, "Now we know you’re possessed by a demon! Both Abraham and the prophets died, and yet you say, ‘If anyone obeys my teaching, he will never taste of death.’ You aren’t greater than our father Abraham who died, are you? And the prophets died too! Who do you claim to be?" Jesus replied, "If I glorify myself, my glory is worthless.

The one who glorifies me is my Father, about whom you people say, ‘He is our God.’ Yet you do not know him, but I know him. If I say that I do not know him, I will be a liar like you. But I do know him, and I obey his teaching. Your father Abraham was overjoyed to see my day, and he saw it and was glad." Then the Jewish people who had been listening to him replied, "You are not yet fifty years old! Have you seen Abraham?" Jesus said to them, "I tell you the solemn truth, before Abraham came into existence, I am!" Then they picked up stones to throw at him, but Jesus hid himself and went out from the temple area. We should observe, first, in this passage, what blasphemous and slanderous language was addressed to our Lord by His enemies. We read that the Jews "Aren't we correct in saying that you are a Samaritan and are possessed by a demon?" Silenced in argument, these wicked men resorted to personal abuse . To lose temper, and call names, is a common sign of a defeated cause. Nicknames, insulting epithets, and violent language, are favorite weapons with the devil. When other means of carrying on his warfare fail, he stirs up his servants to smite with the tongue. Grievous indeed are the sufferings which the saints of God have had to endure from the tongue in every age. Their characters have been slandered.
