Let us hear the conclusion of the whole matter: Fear God, and keep his commandments: for this is the whole duty of man.

Wesley's Notes

12:13 The conclusion - The sum of all that hath been said or written by wise men. Fear God - Which is put here, for all the inward worship of God, reverence, and love, and trust, and a devotedness of heart to serve and please him. The whole - It is his whole work and business, his whole perfection and happiness; it is the sum of what he need either know, or do, or enjoy.

Jamieson-Fausset-Brown Bible Commentary

13. The grand inference of the whole book.

Fear God-The antidote to following creature idols, and "vanities," whether self-righteousness (Ec 7:16, 18), or wicked oppression and other evils (Ec 8:12, 13), or mad mirth (Ec 2:2; 7:2-5), or self-mortifying avarice (Ec 8:13, 17), or youth spent without God (Ec 11:9; 12:1).

this is the whole duty of man-literally, "this is the whole man," the full ideal of man, as originally contemplated, realized wholly by Jesus Christ alone; and, through Him, by saints now in part, hereafter perfectly (1Jo 3:22-24; Re 22:14).

Matthew Henry's Concise Commentary

12:8-14 Solomon repeats his text, VANITY OF VANITIES, ALL IS VANITY. These are the words of one that could speak by dear-bought experience of the vanity of the world, which can do nothing to ease men of the burden of sin. As he considered the worth of souls, he gave good heed to what he spake and wrote; words of truth will always be acceptable words. The truths of God are as goads to such as are dull and draw back, and nails to such as are wandering and draw aside; means to establish the heart, that we may never sit loose to our duty, nor be taken from it. The Shepherd of Israel is the Giver of inspired wisdom. Teachers and guides all receive their communications from him. The title is applied in Scripture to the Lord Jesus Christ, the Son of God. The prophets sought diligently, what, or what manner of time, the Spirit of Christ in them did signify, when it testified beforehand the sufferings of Christ, and the glory that should follow. To write many books was not suited to the shortness of human life, and would be weariness to the writer, and to the reader; and then was much more so to both than it is now. All things would be vanity and vexation, except they led to this conclusion, That to fear God, and keep his commandments, is the whole of man. The fear of God includes in it all the affections of the soul towards him, which are produced by the Holy Spirit. There may be terror where there is no love, nay, where there is hatred. But this is different from the gracious fear of God, as the feelings of an affectionate child. The fear of God, is often put for the whole of true religion in the heart, and includes its practical results in the life. Let us attend to the one thing needful, and now come to him as a merciful Saviour, who will soon come as an almighty Judge, when he will bring to light the things of darkness, and manifest the counsels of all hearts. Why does God record in his word, that ALL IS VANITY, but to keep us from deceiving ourselves to our ruin? He makes our duty to be our interest. May it be graven in all our hearts. Fear God, and keep his commandments, for this is all that concerns man.

Matthew Henry's Whole Bible Commentary

Verses 13-14

The great enquiry which Solomon prosecutes in this book is, What is that good which the sons of men should do? ch. 2:3. What is the true way to true happiness, the certain means to attain our great end? He had in vain sought it among those things which most men are eager in pursuit of, but here, at length, he has found it, by the help of that discovery which God anciently made to man (Job 28:28), that serious godliness is the only way to true happiness: Let us hear the conclusion of the whole matter, the return entered upon the writ of enquiry, the result of this diligent search; you shall have all I have been driving at in two words. He does not say, Do you hear it, but Let us hear it; for preachers must themselves be hearers of that word which they preach to others, must hear it as from God; those are teachers by the halves who teach others and not themselves, Rom. 2:21. Every word of God is pure and precious, but some words are worthy of more special remark, as this; the Masorites begin it with a capital letter, as that Deu. 6:4. Solomon himself puts a nota bene before it, demanding attention in these words, Let us hear the conclusion of the whole matter. Observe here,

I. The summary of religion. Setting aside all matters of doubtful disputation, to be religious is to fear God and keep his commandments. 1. The root of religion is fear of God reigning in the heart, and a reverence of his majesty, a deference to his authority, and a dread of his wrath. Fear God, that is, worship God, give him the honour due to his name, in all the instances of true devotion, inward and outward. See Rev. 14:7. 2. The rule of religion is the law of God revealed in the scriptures. Our fear towards God must be taught by his commandments (Isa. 29:13), and those we must keep and carefully observe. Wherever the fear of God is uppermost in the heart, there will be a respect to all his commandments and care to keep them. In vain do we pretend to fear God if we do not make conscience of our duty to him.

II. The vast importance of it: This is the whole of man; it is all his business and all his blessedness; our whole duty is summed up in this and our whole comfort is bound up in this. It is the concern of every man, and ought to be his chief and continual care; it is the common concern of all men, of their whole time. It is nothing to a man whether he be rich or poor, high or low, but it is the main matter, it is all in all to a man, to fear God and do as he bids him.

III. A powerful inducement to this, v. 14. We shall see of what vast consequence it is to us that we be religious if we consider the account we must every one of us shortly give of himself to God; thence he argued against a voluptuous and vicious life (ch. 11:9), and here for a religious life: God shall bring every work into judgment. Note, 1. There is a judgment to come, in which every man's eternal state will be finally determined. 2. God himself will be the Judge, God-man will, not only because he has a right to judge, but because he is perfectly fit for it, infinitely wise and just. 3. Every work will then be brought into judgment, will be enquired into and called over again. It will be a day to bring to remembrance every thing done in the body. 4. The great thing to be then judged of concerning every work is whether it be good or evil, conformable to the will of God or a violation of it. 5. Even secret things, both good and evil, will be brought to light, and brought to account, in the judgment of the great day (Rom. 2:16); there is no good work, no bad work, hid, but shall then be made manifest. 6. In consideration of the judgment to come, and the strictness of that judgment, it highly concerns us now to be very strict in our walking with God, that we may give up our account with joy.
