John 10:17

Therefore doth the Father love me, because I lay down my life, &c. Christ here speaketh of himself, as made man for the redemption of mankind: or rather, as he was our Redeemer, both God and man: for he laid down his life, and died as man, and had power to take it up again, as God. Yet the command of laying it down, he as man received from the Father: thus as man, he was obedient to him even to the death on the cross. See Philippians ii. 8. (Witham)

[a.] That his laying down his life for the sheep was the condition, the performance of which entitled him to the honours and powers of his exalted state (v. 17): "Therefore doth my Father love me, because I lay down my life. Upon these terms I am, as Mediator, to expect my Father's acceptance and approbation, and the glory designed me—that I become a sacrifice for the chosen remnant." Not but that, as the Son of God, he was beloved of his Father from eternity, but as God-man, as Immanuel, he was therefore beloved of the Father because he undertook to die for the sheep; therefore God's soul delighted in him as his elect because herein he was his faithful servant (Isa 42 1); therefore he said, This is my beloved Son. What an instance is this of God's love to man, that he loved his Son the more for loving us! See what a value Christ puts upon his Father's love, that, to recommend himself to that, he would lay down his life for the sheep. Did he think God's love recompence sufficient for all his services and sufferings, and shall we think it too little for ours, and court the smiles of the world to make it up? Therefore doth my Father love me, that is, me, and all that by faith become one with me; me, and the mystical body, because I lay down my life.

Verses 10-18 Christ is a good Shepherd; many who were not thieves, yet were careless in their duty, and by their neglect the flock was much hurt. Bad principles are the root of bad practices. The Lord Jesus knows whom he has chosen, and is sure of them; they also know whom they have trusted, and are sure of Him. See here the grace of Christ; since none could demand his life of him, he laid it down of himself for our redemption. He offered himself to be the Saviour; Lo, I come. And the necessity of our case calling for it, he offered himself for the Sacrifice. He was both the offerer and the offering, so that his laying down his life was his offering up himself. From hence it is plain, that he died in the place and stead of men; to obtain their being set free from the punishment of sin, to obtain the pardon of their sin; and that his death should obtain that pardon. Our Lord laid not his life down for his doctrine, but for his sheep.
