John Gill

And he said, therefore said I unto you,.... Referring to Joh 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 Joh 6:44.
