Moses calls Israel's mercies to remembrance. (1-9) The Divine wrath on those who flatter themselves in their wickedness. (10-21) The ruin of the Jewish nation. (22-28) Secret things belong unto God. (29)
Verses 1-9 Both former mercies, and fresh mercies, should be thought on by us as motives to obedience. The hearing ear, and seeing eye, and the understanding heart, are the gift of God. All that have them, have them from him. God gives not only food and raiment, but wealth and large possessions, to many to whom he does not give grace. Many enjoy the gifts, who have not hearts to perceive the Giver, nor the true design and use of the gifts. We are bound, in gratitude and interest, as well as in duty and faithfulness, to keep the words of the covenant.
Verses 10-21 The national covenant made with Israel, not only typified the covenant of grace made with true believers, but also represented the outward dispensation of the gospel. Those who have been enabled to consent to the Lord's new covenant of mercy and grace in Jesus Christ, and to give up themselves to be his people, should embrace every opportunity of renewing their open profession of relation to him, and their obligation to him, as the God of salvation, walking according thereto. The sinner is described as one whose heart turns away from his God; there the mischief begins, in the evil heart of unbelief, which inclines men to depart from the living God to dead idols. Even to this sin men are now tempted, when drawn aside by their own lusts and fancies. Such men are roots that bear gall and wormwood. They are weeds which, if let alone, overspread the whole field. Satan may for a time disguise this bitter morsel, so that thou shalt not have the natural taste of it, but at the last day, if not before, the true taste shall be discerned. Notice the sinner's security in sin. Though he hears the words of the curse, yet even then he thinks himself safe from the wrath of God. There is scarcely a threatening in all the book of God more dreadful than this. Oh that presumptuous sinners would read it, and tremble! for it is a real declaration of the wrath of God, against ungodliness and unrighteousness of man.
Verses 22-28 Idolatry would be the ruin of their nation. It is no new thing for God to bring desolating judgments on a people near to him in profession. He never does this without good reason. It concerns us to seek for the reason, that we may give glory to God, and take warning to ourselves. Thus the law of Moses leaves sinners under the curse, and rooted out of the Lord's land; but the grace of Christ toward penitent, believing sinners, plants them again in their land; and they shall no more be pulled up, being kept by the power of God.
Verse 29 Moses ends his prophecy of the Jews' rejection, just as St. Paul ends his discourse on the same subject, when it began to be fulfilled, ( Romans 11:33 ) . We are forbidden curiously to inquire into the secret counsels of God, and to determine concerning them. But we are directed and encouraged, diligently to seek into that which God has made known. He has kept back nothing that is profitable for us, but only that of which it is good for us to be ignorant. The end of all Divine revelation is, not to furnish curious subjects of speculation and discourse, but that we may do all the words of this law, and be blessed in our deed. This, the Bible plainly reveals; further than this, man cannot profitably go. By this light he may live and die comfortably, and be happy for ever.
