John 6:64

For He "knew from the beginning who they were that believed not, and who should betray Him." "And He said, Therefore said I unto you, that no man can come unto Me except it were given unto Him from above from My Father." Here the Evangelist intimates to us the voluntary character of the Dispensation, and His endurance of evil. Nor is the, "from the beginning," put here without a cause, but that thou mayest be aware of His foreknowledge from the first, and that before the words were uttered, and not after the men had murmured nor after they had been offended, He knew the traitor, but before, which was an attribute of Godhead. Then He added, "Except it be given him from above from My Father"; thus persuading them to deem God His Father, not Joseph, and showing them that it is no common thing to believe in Him. As though He had said, "Unbelievers disturb Me not; trouble Me not, astonish Me not. I know of old before they were created, I know to whom the Father hath given to believe"; and do thou, when thou hearest that "He hath given," imagine not merely an arbitrary distribution, but that if any hath rendered himself worthy to receive the gift, he hath received it.

"But there are some of you that believe not." Again, according to His custom, He addeth weight to His words, by foretelling what would come to pass, and by showing that He spake thus not from desire of honor from them, but because He cared for them. And when He said "some," He excepted the disciples. For at first He said, "Ye have both seen Me, and believe not"; but here, "There are some of you that believe not." For He "knew from the beginning who they were that believed not, and who should betray Him." Here the Evangelist intimates to us the voluntary character of the Dispensation, and His endurance of evil. Nor is the, "from the beginning," put here without a cause, but that thou mayest be aware of His foreknowledge from the first, and that before the words were uttered, and not after the men had murmured nor after they had been offended, He knew the traitor, but before, which was an attribute of Godhead.

"But," saith He, "there are some among you that believe not." He said not There are some among you that understand not; but He told the cause why they understand not "There are some among you that believe not," and therefore they understand not, because they believe not. For the prophet has said, "If ye believe not, ye shall not understand." We are united by faith, quickened by understanding. Let us first adhere to Him through faith, that there may be that which may be quickened by understanding. For he who adheres not resists; he that resists believes not. And how can he that resists be quickened? He is an adversary to the ray of light by which he should be penetrated: he turns not away his eye, but shuts his mind. "There are," then, "some who believe not." Let them believe and open, let them open and be illumined. "For Jesus knew from the beginning who they were that believed, and who should betray Him." For Judas also was there. Some indeed, were offended; but he remained to watch his opportunity, not to understand. And because he remained for that purpose, the Lord kept not silence concerning him. He described him not by name, but neither was He silent about him; that all might fear though only one should perish.
