48 The Jews then said, "That clinches it. We were right all along when we called you a Samaritan and said you were crazy - demon-possessed!" 49 Jesus said, "I'm not crazy. I simply honor my Father, while you dishonor me. 50 I am not trying to get anything for myself. God intends something gloriously grand here and is making the decisions that will bring it about.
51 I say this with absolute confidence. If you practice what I'm telling you, you'll never have to look death in the face." 52 At this point the Jews said, "Now we know you're crazy. Abraham died. The prophets died. And you show up saying, 'If you practice what I'm telling you, you'll never have to face death, not even a taste.' 53 Are you greater than Abraham, who died? And the prophets died! Who do you think you are!" 54 Jesus said, "If I turned the spotlight on myself, it wouldn't amount to anything. But my Father, the same One you say is your Father, put me here at this time and place of splendor. 55 You haven't recognized him in this. But I have. If I, in false modesty, said I didn't know what was going on, I would be as much of a liar as you are. But I do know, and I am doing what he says. 56 Abraham - your 'father' - with jubilant faith looked down the corridors of history and saw my day coming. He saw it and cheered." 57 The Jews said, "You're not even fifty years old - and Abraham saw you?" 58 "Believe me," said Jesus, "I am who I am long before Abraham was anything."

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.
