Verse 1-5 — Here is a parable or similitude, taken from the customs of the East, in the management of sheep. Men, as creatures depending on their Creator, are called the sheep of his pasture. The church of God in the world is as a sheep-fold, exposed to deceivers and persecutors. The great Shepherd of the sheep knows all that are his, guards them by his providence, guides them by his Spirit and word, and goes before them, as the Eastern shepherds went before their sheep, to set them in the way of his steps. Ministers must serve the sheep in their spiritual concerns. The Spirit of Christ will set before them an open door. The sheep of Christ will observe their Shepherd, and be cautious and shy of strangers, who would draw them from faith in him to fancies about him.
Verse 6-9 — Many who hear the word of Christ, do not understand it, because they will not. But we shall find one scripture expounding another, and the blessed Spirit making known the blessed Jesus. Christ is the Door. And what greater security has the church of God than that the Lord Jesus is between it and all its enemies? He is a door open for passage and communication. Here are plain directions how to come into the fold; we must come in by Jesus Christ as the Door. By faith in him as the great Mediator between God and man. Also, we have precious promises to those that observe this direction. Christ has all that care of his church, and every believer, which a good shepherd has of his flock; and he expects the church, and every believer, to wait on him, and to keep in his pasture.
Verse 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.
Verse 19-21 — Satan ruins many, by putting them out of conceit with the word and ordinances. Men would not be laughed out of their necessary food, yet suffer themselves thus to be laughed out of what is far more necessary. If our zeal and earnestness in the cause of Christ, especially in the blessed work of bringing his sheep into his fold, bring upon us evil names, let us not heed it, but remember our Master was thus reproached before us.
Verse 22-30 — All who have any thing to say to Christ, may find him in the temple. Christ would make us to believe; we make ourselves doubt. The Jews understood his meaning, but could not form his words into a full charge against him. He described the gracious disposition and happy state of his sheep; they heard and believed his word, followed him as his faithful disciples, and none of them should perish; for the Son and the Father were one. Thus he was able to defend his sheep against all their enemies, which proves that he claimed Divine power and perfection equally with the Father.
Verse 31-38 — Christ's works of power and mercy proclaim him to be over all, God blessed for evermore, that all may know and believe He is in the Father, and the Father in Him. Whom the Father sends, he sanctifies. The holy God will reward, and therefore will employ, none but such as he makes holy. The Father was in the Son, so that by Divine power he wrought his miracles; the Son was so in the Father, that he knew the whole of His mind. This we cannot by searching find out to perfection, but we may know and believe these declarations of Christ.
Verse 39-42 — No weapon formed against our Lord Jesus shall prosper. He escaped, not because he was afraid to suffer, but because his hour was not come. And He who knew how to deliver himself, knows how to deliver the godly our of their temptations, and to make a way for them to escape. Persecutors may drive Christ and his gospel our of their own city or country, but they cannot drive him or it out of the world. When we know Christ by faith in our hearts, we find all that the Scripture saith of him is true.
