(64) There are some of you that believe not.--Later, the word "disciple" became synonymous with the word "believer," but there are those now following Him just as they would follow any Rabbi, and, regarding Him as a merely human teacher, they fall short of the faith which was the first qualification for true discipleship. They had heard, it may be, the Sermon on the Mount, and such teaching as that of Matthew 13. In part they could understand this, and therefore in part believed; but when faith was really needed, it was found not really to exist: for faith is accepting what is not demonstrable to the mere reason, and seeing what is invisible.

From the beginning.--This is a relative term, and is to be interpreted from the context. It means here the beginning of their discipleship. He saw in their hearts the varying kinds of ground on which the good seed fell, and in their acts and words the varying effects. There were hearts like the hardened wayside, but it may have been ploughed; like the stony places, but that shelving rock may have been broken through; like the thorns, but they may have been rooted up; and all may have become, as some were, like the good and fruit-bearing ground.

Verse 64. - But, he adds, there are some of you that believe not. "Some," not many, who were following him yet felt that they could not trust - could not accept his greatest revelations, these Divine assumptions, this spiritual position of his. The Divine humanity, the offered life, the cruel death, of the Son of God, the victory over death, the return to the Father, when put into words or when taught in metaphors even, were grounds of offence. The evangelist adds: For (the γάρ introduces the explanatory clause of the disciple who testified of these things) Jesus knew (knew absolutely, rather than came to know) from the beginning - referring to the commencement of his public ministry, when men began to close round him (John 1:43, 48; John 2:24), not from the beginning of time, or the beginning of their unbelief (Kling); he knew by his Divine penetration into their character, by their manner and spirit, and the nakedness and openness of all hearts before him - who they were that believed not, and who it was that should betray him. Westcott here reminds us that the first indication of the sin of Judas occurs in close association with predictions of the approaching Passion. This foreknowledge of issues is no interference with free self-consciousness in itself. It may imply that the natures thus known contained in themselves the seeds of the future growth. He knew what would be, but he did not compel it. There was possibly some fresh manifestation of feeling, of failing sympathy, even of enmity, which led the evangelist to notice the manner and interpret the mind of the Lord.

6:60-65 The human nature of Christ had not before been in heaven, but being God and man, that wondrous Person was truly said to have come down from heaven. The Messiah's kingdom was not of this world; and they were to understand by faith, what he had said of a spiritual living upon him, and his fulness. As without the soul of man the flesh is of no value, so without the quickening Spirit of God all forms of religion are dead and worthless. He who made this provision for our souls, alone can teach us these things, and draw us unto Christ, that we may live by faith in him. Let us apply to Christ, thankful that it is declared that every one who is willing to come unto him shall be made welcome.But there are some of you that believe not,.... Notwithstanding the ministry they sat under, and the words they heard; for though they professed to believe in Jesus, as the Messiah, yet they did not truly believe in him; their faith was not a living faith, or of a spiritual kind, but a mere historical and temporary one, and was feigned and hypocritical:

for Jesus knew from the beginning; of his ministry, and of their profession of him, being God omniscient, and the searcher of hearts:

who they were that believed not; i.e. in him, as the Arabic version reads: notwithstanding their following him, and professing to believe in him, and the great outward respect and esteem they showed to him, he could see through all those masks they put on, and knew they had no true faith of him in them; and the same knowledge he has of every professor of his name: he knows whether their faith is of the right kind or not; whether they have obtained the like precious faith with God's elect; or whether their profession is only a verbal one. In some copies it is read, "who they were that believed"; who were true believers, as well as who were hypocrites.

And who should betray him: he not only knew how it was with the multitude of the disciples that professed love to him, and faith in him; but he also particularly knew the case of the twelve apostles, and that one of them should betray him, and who he was. This was determined in the decrees of God, and was foretold in the prophecies of the Old Testament, and was predicted by Christ; and the person was pointed at by him before it was done.
