48 The Jews answered him, "Are we not right in saying that you are a Samaritan and have a demon?" 49 Jesus answered, "I have not a demon; but I honor my Father, and you dishonor me. 50 Yet I do not seek my own glory; there is One who seeks it and he will be the judge.
51 Truly, truly, I say to you, if any one keeps my word, he will never see death." 52 The Jews said to him, "Now we know that you have a demon. Abraham died, as did the prophets; and you say, 'If any one keeps my word, he will never taste death.' 53 Are you greater than our father Abraham, who died? And the prophets died! Who do you claim to be?" 54 Jesus answered, "If I glorify myself, my glory is nothing; it is my Father who glorifies me, of whom you say that he is your God. 55 But you have not known him; I know him. If I said, I do not know him, I should be a liar like you; but I do know him and I keep his word. 56 Your father Abraham rejoiced that he was to see my day; he saw it and was glad." 57 The Jews then said to him, "You are not yet fifty years old, and have you seen Abraham?" 58 Jesus said to them, "Truly, truly, I say to you, before Abraham was, I am."

Commentary on John 8:48-53
(Read John 8:48-53)
Observe Christ's disregard of the applause of men. those who are dead to the praises of men can bear their contempt. God will seek the honour of all who do not seek their own. In these verses we have the doctrine of the everlasting happiness of believers. We have the character of a believer; he is one that keeps the sayings of the Lord Jesus. And the privilege of a believer; he shall by no means see death for ever. Though now they cannot avoid seeing death, and tasting it also, yet they shall shortly be where it will be no more forever, Exodus 14:13.
Commentary on John 8:54-59
(Read John 8:54-59)
Christ and all that are his, depend upon God for honour. Men may be able to dispute about God, yet may not know him. Such as know not God, and obey not the gospel of Christ, are put together, Revelation 13:8. The Lord Jesus was made of God Wisdom, Righteousness, Sanctification, and Redemption, to Adam, and Abel, and all that lived and died by faith in him, before Abraham. The Jews were about to stone Jesus for blasphemy, but he withdrew; by his miraculous power he passed through them unhurt. Let us stedfastly profess what we know and believe concerning God; and if heirs of Abraham's faith, we shall rejoice in looking forward to that day when the Saviour shall appear in glory, to the confusion of his enemies, and to complete the salvation of all who believe in him.
