John 6:36-37

But I said, &c. But valuable as these blessings of my grace are, you are little disposed to pursue and accept them. For ye also have seen me, and believe not You have seen a manifestation of my true character, in my life and conversation, and have been eye-witnesses of the ample proofs which I had given of my divine mission, in the miracles which I have already performed; signs certainly sufficient to convince you that I am the Messiah: nevertheless, you do not believe that I am he, but reject me as an impostor. Therefore, your infidelity proceeds not from want of evidence, as you pretend, (John 6:30,) but from the perverseness of your own disposition. All that the Father giveth me shall come to me Nevertheless, though you reject me, yet I shall not be universally rejected, nor shall the purposes of my mission be entirely frustrated; for all that hearken to the teaching of my Father, and in consequence thereof see themselves to be in a lost estate, guilty, depraved, weak, and wretched, and therefore follow the drawings of his grace, (see John 6:44, where our Lord's meaning is explained,) will come to me By faith: such as these the Father in a peculiar manner giveth to the Son. And him that cometh to me Being thus convinced of sin, humbled, and penitent; I will in no wise cast out I will give him pardon, holiness, and happiness, and even heaven, if he continue in the faith, and be not moved away from the hope of the gospel. Thus our Lord encouraged his disciples, who had already believed on him; and at the same time invited those who were disposed to believe, from the consideration that he would not reject them, however low their circumstances might be, however vile they might appear in their own eyes, or however much they might have formerly injured him, by speaking evil of him and opposing him. “The expression, ου μη εκβαλω εξω, is extremely beautiful and emphatical. It represents an humble supplicant, as coming into the house of some prince, or other great person, to cast himself at his feet, and to commit himself to his protection and care. He might fear his petition would be rejected, and he be thrust out of doors: but our Lord assures him to the contrary. His house and heart are large enough to receive, shelter, and supply all the indigent and distressed.” Doddridge.
