We are here taught to live a life of communion with God; and without controversy great is this mystery of godliness, and of great consequence to us, and, as is here shown, will be of unspeakable advantage.

I.We must have a continual regard to God's precepts, Pro 3:1, Pro 3:2.

1.We must, (1.) Fix God's law, and his commandments, as our rule, by which we will in every thing be ruled and to which we will yield obedience. (2.) We must acquaint ourselves with them; for we cannot be said to forget that which we never knew. (3.) We must remember them so that they may be ready to us whenever we have occasion to use them. (4.) Our wills and affections must be subject to them and must in every thing conform to them. Not only our heads, but our hearts, must keep God's commandments; in them, as in the ark of the testimony, both the tables of the law must be deposited.

2.To encourage us to submit ourselves to all the restraints and injunctions of the divine law, we are assured (Pro 3:2) that it is the certain way to long life and prosperity. (1.) It is the way to be long-lived. God's commandments shall add to us length of days; to a good useful life on earth, they shall add an eternal life in heaven, length of days for ever and ever, Psa 21:4. God shall be our life and the length of our days, and that will be indeed long life, with an addition. But, because length of days may possibly become a burden and a trouble, it is promised, (2.) That it shall prove the way to be easy too, so that even the days of old age shall not be evil days, but days in which thou shalt have pleasure: Peace shall they be continually adding to thee. As grace increases, peace shall increase; and of the increase of Christ's government and peace, in the heart as well as in the world, there shall be no end. Great and growing peace have those that love the law.

II.We must have a continual regard to God's promises, which go along with his precepts, and are to be received, and retained, with them (Pro 3:3): "Let not mercy and truth forsake thee, God's mercy in promising, and his truth in performing. Do not forfeit these, but live up to them, and preserve thy interest in them; do not forget these, but live upon them, and take the comfort of them. Bind them about thy neck, as the most graceful ornament." It is the greatest honour we are capable of in this world to have an interest in the mercy and truth of God. "Write to them upon the table of thy heart, as dear to thee, thy portion, and most delightful entertainment; take a pleasure in applying them and thinking them over." Or it may be meant of the mercy and truth which are our duty, piety and sincerity, charity towards men, fidelity towards God. Let these be fixed and commanding principles in thee. To encourage us to do this we are assured (Pro 3:4) that this is the way to recommend ourselves both to our Creator and fellow-creatures: So shalt thou find favour and good understanding. 1. A good man seeks the favour of God in the first place, is ambitious of the honour of being accepted of the Lord, and he shall find that favour, and with it a good understanding; God will make the best of him, and put a favourable construction upon what he says and does. He shall be owned as one of Wisdom's children, and shall have praise with God, as one having that good understanding which is ascribed to all those that do his commandments. 2. He wishes to have favour with men also (as Christ had, Luk 2:52), to be accepted of the multitude of his brethren (Est 10:3), and that he shall have; they shall understand him aright, and in his dealings with them he shall appear to be prudent, shall act intelligently and with discretion. He shall have good success (so some translate it), the common effect of good understanding.

III.We must have a continual regard to God's providence, must own and depend upon it in all our affairs, both by faith and prayer. 1. By faith. We must repose an entire confidence in the wisdom, power, and goodness of God, assuring ourselves of the extent of his providence to all the creatures and all their actions. We must therefore trust in the Lord with all our hearts (Pro 3:5); we must believe that he is able to do what he will, wise to do what is best, and good, according to his promise, to do what is best for us, if we love him, and serve him. We must, with an entire submission and satisfaction, depend upon him to perform all things for us, and not lean to our own understanding, as if we could, by any forecast of our own, without God, help ourselves, and bring our affairs to a good issue. Those who know themselves cannot but find their own understanding to be a broken reed, which, if they lean to, will certainly fail them. In all our conduct we must be diffident of our own judgment, and confident of God's wisdom, power, and goodness, and therefore must follow Providence and not force it. That often proves best which was least our own doing. 2. By prayer (Pro 3:6): In all thy ways acknowledge God. We must not only in our judgment believe that there is an over-ruling hand of God ordering and disposing of us and all our affairs, but we must solemnly own it, and address ourselves to him accordingly. We must ask his leave, and not design any thing but what we are sure is lawful. We must ask his advice and beg direction from him, not only when the case is difficult (when we know not what to do, no thanks to us that we have our eyes up to him), but in every case, be it ever so plain, We must ask success of him, as those who know the race is not to the swift. We must refer ourselves to him as one from whom our judgment proceeds, and patiently, and with a holy indifferency, wait his award. In all our ways that prove direct, and fair, and pleasant, in which we gain our point to our satisfaction, we must acknowledge God with thankfulness. In all our ways that prove cross and uncomfortable, and that are hedged up with thorns, we must acknowledge God with submission. Our eye must be ever towards God; to him we must, in every thing, make our requests known, as Jephthah uttered all his words before the Lord in Mizpeh, Jdg 11:11. For our encouragement to do this, it is promised, "He shall direct thy paths, so that thy way shall be safe and good and the issue happy at last." Note, Those that put themselves under a divine guidance shall always have the benefit of it. God will give them that wisdom which is profitable to direct, so that they shall not turn aside into the by-paths of sin, and then will himself so wisely order the event that it shall be to their mind, or (which is equivalent) for their good. Those that faithfully follow the pillar of cloud and fire shall find that though it may lead them about it leads them the right way and will bring them to Canaan at last.

Trust in the Lord with all thine heart,.... Not in a creature, the best, the holiest, and the highest; not in any creature enjoyment, as riches, strength, and wisdom; nor in any outward privilege, arising from natural descent and education; not in a man's self, in his own heart, which is deceitful; nor in any works of righteousness done by him; not in a profession of religion, or the duties of it, ever so well performed; not in frames, nor in graces, and the exercise of them; no, not in faith or trust itself: but in the Lord, the object of all grace, and in him only; in Jehovah the Father, as the God of nature and providence, for all temporal blessings; and as the God of all grace, for all spiritual blessings, and all the needful supplies of grace; and for eternal happiness, which he has provided, promised, and freely gives. Trust in him at all times; in times of affliction, temptation, and darkness: there is a great deal of reason for it; all power and strength are in him to help; his love, grace, and mercy, move him to it, and are always the same: the consideration of what he has done for others that have trusted in him, and for ourselves in times past, should induce and encourage to it; as also the happiness of those that trust in him, who enjoy peace and safety; and his displeasure at those that show any diffidence of him, or distrust him. Trust in Jehovah the Son; in his person for acceptance; in his righteousness for justification; in his blood for pardon; in his fulness for supply; in his power for protection and preservation; and in him alone for salvation and eternal life. Trust in Jehovah the Spirit, to carry on and finish the work of grace upon the heart; of which a saint may be confident that where it is begun it will be completed. And this trust in Father, Son, and Spirit, should be "with all the heart", cordial and sincere. The phrase denotes not so much the strength of faith as the sincerity of it; it signifies a faith unfeigned; it is not saying, or professing, that a man believes and trusts in the Lord; but it is with the heart, and with his whole heart, that he believes unto righteousness, if he believes aright; see Rom 10:10;

and lean not unto thine own understanding; or trust not to that; for it stands opposed to trusting in the Lord. Men should not depend upon their own wisdom and understanding, in the conduct of civil life, but should seek the direction and blessing of Providence, or otherwise will meet with disappointment; and, when they succeed, should ascribe it not to their own prudence and wisdom, but to the goodness of God; for "bread" is not always "to the wise, nor riches to men of understanding", Ecc 9:11; and much less should men lean to their own understanding in matters of religion; a natural man has no understanding of spiritual things, of the things of the Gospel, nor indeed any practical understanding of things moral, Rom 3:11, Jer 4:22. The understanding of man is darkened by sin; yea, is darkness itself; it is like the first earth, covered with darkness, till light is let into it, and therefore not to be leaned unto and depended on, Eph 4:18. There is a necessity of a new heart and spirit, of an understanding to be given, in order to understand spiritual and divine things, Eze 36:26; for though these are not contrary to the reason and understanding of men; yet they are above them, and cannot be discovered, reached, comprehended, and accounted for by them, Mat 16:17. Nay, there are some things in the Gospel, which, though plain to an enlightened understanding by the word of God, yet the manner how they are cannot be apprehended: as the doctrines of a trinity of Persons; of the generation of the Son of God; the procession of the Spirit; the union of the two natures in Christ; the resurrection of the dead, &c. In short, not our reason and understanding at best, and much less as carnal and unsanctified, but the word of God only is our rule of judgment, and the standard of our faith and practice; and to that we should have recourse and be directed by it, and not lean to our own understandings.

Trust . . . heart--This is the center and marrow of true wisdom (Pro 22:19; Pro 28:25). The positive duty has its corresponding negation in the admonition against self-confidence.
