(17) The Lord thy God which teacheth thee to profit.--The words applied to the natural human, perhaps we may add, to the specially national, desire, to make a good investment. The question what was profitable? was one to which men returned very different answers. It was the work of the true Redeemer to lead men to the one true imperishable gain (comp. Matthew 16:26), to lead them in the one right way (John 14:4-6).

Verse 17. - The Lord... which teacheth thee to profit. God's teachings are all directed to the "profit" of those to whom they are addressed; and, if received in a proper spirit, actually "profit" them more than anything else can do. "All Scripture is given by inspiration of God, and is profitable" (2 Timothy 3:16). Very profitable also are the teachings of God's providence, which chasten men, warn men, and tend to keep men in the right path.

48:16-22 The Holy Spirit qualifies for service; and those may speak boldly, whom God and his Spirit send. This is to be applied to Christ. He was sent, and he had the Spirit without measure. Whom God redeems, he teaches; he teaches to profit by affliction, and then makes them partakers of his holiness. Also, by his grace he leads them in the way of duty; and by his providence he leads in the way of deliverance. God did not afflict them willingly. If their sins had not turned them away, their peace should have been always flowing and abundant. Spiritual enjoyments are ever joined with holiness of life and regard to God's will. It will make the misery of the disobedient the more painful, to think how happy they might have been. And here is assurance given of salvation out of captivity. Those whom God designs to bring home to himself, he will take care of, that they want not for their journey. This is applicable to the grace laid up for us in Jesus Christ, from whom all good flows to us, as the water to Israel out of the rock, for that Rock was Christ. The spiritual blessings of redemption, and the rescue of the church from antichristian tyranny, are here pointed to. But whatever changes take place, the Lord warned impenitent sinners that no good would come to them; that inward anguish and outward trouble, which spring from guilt and from the Divine wrath, must be their portion for ever.Thus saith the Lord, thy Redeemer,.... A character peculiar to Christ, who engaged in covenant to be the Redeemer of his people; was promised and prophesied of as such; and who came into this world for this purpose, and has obtained eternal redemption:

the Holy One of Israel; who came of Israel as man, and as such was holy, and without any spot or stain of sin and who, as God, is the most holy, in his nature and works; and, as Mediator, the Sanctifier of Israel, and is in the midst of them as such:

I am the Lord thy God; and so fit to be the Redeemer and Sanctifier of them; and happy are those who can say with Thomas, "my Lord and my God"; and who further describes himself, and declares his work and office:

which teacheth thee to profit; or "teacheth thee profitable things" (p); as the whole of the Gospel ministry is, whether it respects doctrines relating to the knowledge of the Persons in the Godhead; the knowledge of God in Christ; the person and offices of Christ; and the person and operations of the Spirit: or to the knowledge of man; his lost and depraved state; having sinned in Adam, the guilt of his sin is imputed to him, and a corrupt nature propagated; the bias of the mind being to evil, and man impotent to all that is good: or to the way of salvation by the grace of God, as the fruit and effect of the love of God; the doctrines of his eternal love, and of redemption by Christ; of justification by his righteousness; pardon by his blood; atonement by his sacrifice; regeneration by his Spirit and grace; and of the perseverance of the saints in faith and holiness. These are profitable doctrines, which serve to display the riches of divine grace, make for the glory of the Redeemer, and the good of souls, their peace, joy, comfort, and salvation. These are the wholesome words of our Lord Jesus. Or whether these teachings respect ordinances which Christ has appointed, and in his word and by his Spirit teaches men to observe; and which are profitable to lead to him, are breasts of consolation from him, and the means of spiritual strength: or whether they regard the duties of religion, the performance of good works; which, though not profitable to God, and not meritorious of anything from him, yet are profitable to men; to others by way of example, and otherwise, and to the doers of them, who find pleasure, peace, and advantage, by them. Christ was a teacher of these things when on earth, and he still teaches them by his ministers, whom he commissions and qualifies, and by his Spirit accompanying their ministrations:

which leadeth thee by the way that thou shouldest go; Christ leads his people out of the wrong way, in which they naturally are, into the right way; to himself, as the way to the Father, and as the way of salvation, and unto eternal life; he takes them by the hand, and teaches them to go in the path of faith, and to walk in him by it; he leads them in the ways of truth and righteousness, in the highway of holiness, in the path of duty; and, though in a rough way of afflictions, yet in a right way to heaven and happiness.
