(8) For I have given unto them the words which thou gavest me.--Our Lord explains in this verse how the disciples attained to the knowledge He had spoken of in John 17:7, and lays stress in the first place on His own work in teaching them, "I, on My part, have given unto them," and on the matter taught as that which the Father had committed unto Him (John 12:49).

And they have received them.--Not less emphatic is the work of the disciples themselves. "They on their part received them." Others had been taught, and did not receive. The teaching was the same; the varying effect was in the heart of the hearer. (Comp. John 1:12; John 1:18.)

He has spoken of the teaching and the reception. He proceeds to the two-fold result.

And have known (better, and knew) surely that I came out from thee.--Comp. Notes on John 3:2; John 16:30.

And they have believed (better, and they believed) that thou didst send me.--The addition of this clause is in part to be explained as the Hebrew fulness of expression, and in part as an advance on the truth, "I came out from Thee." That He came from God they knew by the harmony of His doctrine with the voice of God, which was already speaking in their consciences. But more than this, they believed Him to be the sent One, the Messiah, whom they expected (John 17:3).

17:6-10. Christ prays for those that are his. Thou gavest them me, as sheep to the shepherd, to be kept; as a patient to the physician, to be cured; as children to a tutor, to be taught: thus he will deliver up his charge. It is a great satisfaction to us, in our reliance upon Christ, that he, all he is and has, and all he said and did, all he is doing and will do, are of God. Christ offered this prayer for his people alone as believers; not for the world at large. Yet no one who desires to come to the Father, and is conscious that he is unworthy to come in his own name, need be discouraged by the Saviour's declaration, for he is both able and willing to save to the uttermost, all that come unto God by him. Earnest convictions and desires, are hopeful tokens of a work already wrought in a man; they begin to evidence that he has been chosen unto salvation, through sanctification of the Spirit and belief of the truth. They are thine; wilt thou not provide for thine own? Wilt thou not secure them? Observe the foundation on which this plea is grounded, All mine are thine, and thine are mine. This speaks the Father and Son to be one. All mine are thine. The Son owns none for his, that are not devoted to the service of the Father.For I have given unto them the words,.... Not commands, but doctrines; and these not the doctrines of men; nor any of the divers and strange doctrines; but what are called in Scripture the doctrine of God, of Christ, of the apostles, are agreeably to the Scriptures, and according to godliness; and are styled the word of truth, of faith, of righteousness, of peace and reconciliation, of life and salvation, and of the Gospel; and which Christ gave to his disciples, and gifts along with them to preach them, and abilities to help them:

which thou gavest me; for the words and doctrines which Christ, as the great prophet in Israel spoke, were not his own, but his Father's; and these were given him to speak and deliver to others, and in which he was faithful; so Jonathan ben Uzziel (l) paraphrases the text in Deuteronomy 18:18; concerning that prophet, the Messiah, God would raise up, after this manner;

"a prophet will I raise up unto them from among their brethren, in whom the Holy Spirit shall be, like unto thee; , "and I will give the words", of my prophecy into his mouth, and he shall speak with them all that I have commanded.''

And so the Messiah Jesus did:

and they have received them; willingly and gladly, with reverence and meekness, with love, and thankfulness; so as to understand them and believe them, and so as to be affectionately and closely attached to them:

and have known surely that I came out from thee; which is meant, not of his eternal filiation, but of his constitution and commission, as Mediator by his Father: of which they had certain knowledge, full assurance of faith, and sincerely owned and confessed being fully persuaded he was the true Messiah, and no impostor:

and they have believed that thou didst send me; into this world, to seek and to save lost sinners, to redeem all the chosen ones, and perform everything necessary to their salvation.
