No man taketh it from me, but I lay it down of myself. I have power to lay it down, and I have power to take it again. This commandment have I received of my Father.

People's New Testament

10:18 I lay it down of myself. His life. He gave himself for man of his free will. He laid it down on the cross; he took it up when he rose from the dead. Abbott says of the lesson in Joh 10:1-18, I understand this lesson to be a parable with a double application. First, Christ compares the Pharisees to shepherds, himself to the door, and declares that those only are true shepherds who enter through the door; that is, through Christ and his authority. All others are thieves and robbers. Then he changes the application and declares himself the good shepherd whose praises David and Isaiah sung, and indicates the nature of the service that he will render unto his sheep by giving for them his life.

Wesley's Notes

10:18 I lay it down of myself - By my own free act and deed. I have power to lay it down, and I have power to take it again - I have an original power and right of myself, both to lay it down as a ransom, and to take it again, after full satisfaction is made, for the sins of the whole world. This commission have I received of my Father - Which I readily execute. He chiefly spoke of the Father, before his suffering: of his own glory, after it. Our Lord's receiving this commission as mediator is not to be considered as the ground of his power to lay down and resume his life. For this he had in him self, as having an original right to dispose thereof, antecedent to the Father's commission. But this commission was the reason why he thus used his power in laying down his life. He did it in obedience to his Father.

Jamieson-Fausset-Brown Bible Commentary

18. No man taketh it from me, but I lay it down myself: I have power to lay it down, and I have power to take it again-It is impossible for language more plainly and emphatically to express the absolute voluntariness of Christ's death, such a voluntariness as it would be manifest presumption in any mere creature to affirm of his own death. It is beyond all doubt the language of One who was conscious that His life was His own (which no creature's is), and therefore His to surrender or retain at will. Here lay the glory of His sacrifice, that it was purely voluntary. The claim of "power to take it again" is no less important, as showing that His resurrection, though ascribed to the Father, in the sense we shall presently see, was nevertheless His own assertion of His own right to life as soon as the purposes of His voluntary death were accomplished.

This commandment-to "lay down His-life, that He might take it again."

have I received of my Father-So that Christ died at once by "command" of His Father, and by such a voluntary obedience to that command as has made Him (so to speak) infinitely dear to the Father. The necessity of Christ's death, in the light of these profound sayings, must be manifest to all but the superficial student.

Matthew Henry's Concise Commentary

10:10-18 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.
