And he said, Therefore said I unto you, that no man can come unto me, except it were given unto him of my Father.

and he said, 'Because of this I have said to you, No one is able to come unto me, if it may not have been given him from my Father.'

So He added, "That is why I told you that no one can come to me unless it be granted him by the Father."

And he said, This is why I said to you, No man is able to come to me if he is not given the power to do so by the Father.

And so he said, "For this reason, I said to you that no one is able to come to me, unless it has been given to him by my Father."

and he added, "This is why I told you that no one can come to me, unless enabled by the Father."

Therefore have I told you. He again states that faith is an uncommon and remarkable gift of the Spirit of God, that we may not be astonished that the Gospel is not received in every place and by all. For, being ill qualified to turn to our advantage the course of events, we think more meanly of the Gospel, because the whole world does not assent to it. The thought arises in our mind, How is it possible that the greater part of men shall deliberately reject their salvation? Christ therefore assigns a reason why there are so few believers, namely, because no man, whatever may be his acuteness, [1] can arrive at faith by his own sagacity; for all are blind, until they are illuminated by the Spirit of God, and therefore they only partake of so great a blessing whom the Father deigns to make partakers of it. If this grace were bestowed on all without exception, it would have been unseasonable and inappropriate to have mentioned it in this passage; for we must understand that it was Christ's design to show that not many believe the Gospel, because faith proceeds only from the secret revelation of the Spirit. Unless it be given him by my Father. He now uses the word give instead of the word which he formerly used, draw; by which he means that there is no other reason why God draws, than because out of free grace he loves us; for what we obtain by the gift and grace of God, no man procures for himself by his own industry.

Footnotes

1 - "Tant aigu soit il."

Therefore said I unto you - John 6:44. See the note there.
Except it were given unto him - None can come at first, unless he be drawn by the Father; and none can continue, unless he continue under those sacred influences which God gives only to those who do not receive his first graces in vain. St. Augustin himself grants that it was the sole fault of these disciples that they did not believe, and were saved. Quare non Poterant credere, si a me quaeratur, cito respondeo, quia Nolebant. If I be asked why these could not believe, I immediately answer, because they Would Not. Aug. Tract. 53, in Joan.

And he said, therefore said I unto you,.... Referring to John 6:44, where the substance of what is here said, is there delivered; though the Ethiopic version reads, therefore I say unto you, what follows:
that no man can come to me, except it be given him of my Father; which is the same, as to be drawn by the Father; for faith in Christ is the gift of God, and coming to him, is owing to efficacious grace, and is not the produce of man's power and freewill; See Gill on John 6:44.

Therefore said I, &c.--that is, "That was why I spoke to you of the necessity of divine teaching which some of you are strangers to."
except it were given him--plainly showing that by the Father's "drawing" (John 6:44) was meant an internal and efficacious operation, for in recalling the statement here He says, it must be "given to a man to come" to Christ.

No man can come unto me. See note on John 6:44-45.

Unless it be given - And it is given to those only who will receive it on God's own terms.
