II. Concerning every one that hears and reads the words of the prophecy of this book (v. 9): Who is wise? and he shall understand these things. Perhaps the prophet was wont to conclude that sermons he preached with these words, and now he closes with them the whole book, in which he has committed to writing some fragments of the many sermons he had preached. Observe, 1. The character of those that do profit by the truths he delivered: Who is wise and prudent? He shall understand these things, he shall know them. Those that set themselves to understand and know these things thereby make it to appear that they are truly wise and prudent, and will thereby be made more so; and, if any do not understand and know them, it is because they are foolish and unwise. Those that are wise in the doing of their duty, that are prudent in practical religion, are most likely to know and understand both the truths and providences of God, which are a mystery to others, John vii. 17. The secret of the Lord is with those that fear him, Ps. xxv. 14. Who is wise? This intimates a desire that those who read and hear these things would understand them (O that they were wise!) and a complaint that few were so—Who has believed our report? 2. The excellency of these things concerning which we are here instructed: The ways of the Lord are right; and therefore it is our wisdom and duty to know and understand them. The way of God's precepts, in which he requires us to walk, is right, agreeing with the rules of eternal reason and equity and having a direct tendency to our eternal felicity. The ways of God's providence, in which he walks toward us, are all right; no fault is to be found with any thing that God does, for it is all well done. His judgments upon the impenitent, his favours to the penitent, are all right; however they may be perverted and misinterpreted, God will at last be justified and glorified in them all. His ways are equal. 3. The different use which men make of them. (1.) The right ways of God to those that are good are, and will be, a savour of life unto life: The just shall walk in them; they shall conform to the will of God both in his precepts and in his providences, and shall have the comfort of so doing. They shall well understand the mind of God both in his word and in his works; they shall be well reconciled to both, and shall accommodate themselves to God's intention in both. The just shall walk in those ways towards their great end, and shall not come short of it. (2.) The right ways of God will be to those that are wicked a savour of death unto death: The transgressors shall fall not only in their own wrong ways, but even in the right ways of the Lord. Christ, who is a foundation stone to some, is to others a stone of stumbling and a rock of offence. That which was ordained to life becomes through their abuse of it, death to them. God's providences, being not duly improved by them, harden them in sin and contribute to their ruin. God's discovery of himself both in the judgments of his mouth and in the judgments of his hand is to us according as we are affected under it. Recipitur ad modum recipientis—What is received influences according to the qualities of the receiver. The same sun softens wax and hardens clay. But of all transgressors those certainly have the most dangerous fatal falls that fall in the ways of God, that split on the rock of ages, and suck poison out of the balm of Gilead. Let the sinners in Zion be afraid of this.
