21 Later Jesus said to them again, "I am going away. You will search for me but will die in your sin. You cannot come where I am going." 22 The people asked, "Is he planning to commit suicide? What does he mean, 'You cannot come where I am going'?" 23 Jesus continued, "You are from below; I am from above. You belong to this world; I do not. 24 That is why I said that you will die in your sins; for unless you believe that I AM who I claim to be, you will die in your sins." 25 "Who are you?" they demanded. Jesus replied, "The one I have always claimed to be. 26 I have much to say about you and much to condemn, but I won't. For I say only what I have heard from the one who sent me, and he is completely truthful." 27 But they still didn't understand that he was talking about his Father. 28 So Jesus said, "When you have lifted up the Son of Man on the cross, then you will understand that I AM he. I do nothing on my own but say only what the Father taught me. 29 And the one who sent me is with me-he has not deserted me. For I always do what pleases him."

Commentary on John 8:21-29
(Read John 8:21-29)
Those that live in unbelief, are for ever undone, if they die in unbelief. The Jews belonged to this present evil world, but Jesus was of a heavenly and Divine nature, so that his doctrine, kingdom, and blessings, would not suit their taste. But the curse of the law is done away to all that submit to the grace of the gospel. Nothing but the doctrine of Christ's grace will be an argument powerful enough, and none but the Spirit of Christ's grace will be an agent powerful enough, to turn us from sin to God; and that Spirit is given, and that doctrine is given, to work upon those only who believe in Christ. Some say, Who is this Jesus? They allow him to have been a Prophet, an excellent Teacher, and even more than a creature; but cannot acknowledge him as over all, God blessed for evermore. Will not this suffice? Jesus here answers the question. Is this to honour him as the Father? Does this admit his being the Light of the world, and the Life of men, one with the Father? All shall know by their conversion, or in their condemnation, that he always spake and did what pleased the Father, even when he claimed the highest honours to himself.
