64 But there are some of you that believe not. For Jesus knew from the beginning who they were that believed not, and who should betray him.
65 And he said, Therefore said I unto you, that no man can come unto me, except it were given unto him of my Father.
The fact is God does not draw everyone to Himself in a saving sense. But He does give everyone the chance to be saved.
Rom 1:18-22 For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who suppress the truth in unrighteousness, because what may be known of God is manifest in them, for God has shown it to them. For since the creation of the world His invisible attributes are clearly seen, being understood by the things that are made, even His eternal power and Godhead, so that they are without excuse, because, although they knew God, they did not glorify Him as God, nor were thankful, but became futile in their thoughts, and their foolish hearts were darkened. Professing to be wise, they became fools.
Joh 14:22-24 Judas (not Iscariot) said to Him, "Lord, how is it that You will manifest Yourself to us, and not to the world?" Jesus answered and said to him, "If anyone loves Me, he will keep My word; and My Father will love him, and We will come to him and make Our home with him. He who does not love Me does not keep My words; and the word which you hear is not Mine but the Father's who sent Me.
There is a process to "believing", it is not an action assigned by God to man. God, as shown above, gives His goodwill to all men, but some choose to suppress that knowledge. God certainly knows "from the beginning who they were
that believed not". But it does not mean God assigned them that belief. He is actually wrathful only because people suppress the truth.
How does God's manifestation occur in John 14? When a person is responsive to God's word, receives it, then, and only then, the Father's love is poured out.
This was also believed by the Earliest Church Fathers:
4. ... but for the despisers and mockers who avoid and turn themselves away from this light, and who do, as it were, blind themselves, He has prepared darkness suitable to persons who oppose the light, and He has inflicted an appropriate punishment upon those who try to avoid being subject to Him. Submission to God is eternal rest, so that they who shun the light have a place worthy of their flight; and those who fly from eternal rest, have a habitation in accordance with their fleeing. Now, since all good things are with God, they who by their own determination fly from God, do defraud themselves of all good things; and having been [thus] defrauded of all good things with respect to God, they shall consequently fall under the just judgment of God. (Irenaeus [A.D. 120-202], Against Heresies - Book 4 Ch 39 -End)
