Proverbs 4:23

From it. As the heart is the principal part of the body, so the will is the chief power of the soul, from which good or evil proceeds. (Worthington) — A clean heart gives life, a corrupt one, death, Matthew xv. 11, 19.

II. We must keep a watchful eye and a strict hand upon all the motions of our inward man, v. 23. Here is, 1. A great duty required by the laws of wisdom, and in order to our getting and preserving wisdom: Keep thy heart with all diligence. God, who gave us these souls, gave us a strict charge with them: Man, woman, keep thy heart; take heed to thy spirit, Deut 4 9. We must maintain a holy jealousy of ourselves, and set a strict guard, accordingly, upon all the avenues of the soul; keep our hearts from doing hurt and getting hurt, from being defiled by sin and disturbed by trouble; keep them as our jewel, as our vineyard; keep a conscience void of offence; keep out bad thoughts; keep up good thoughts; keep the affections upon right objects and in due bounds. Keep them with all keepings (so the word is); there are many ways of keeping things—by care, by strength, by calling in help, and we must use them all in keeping our hearts; and all little enough, so deceitful are they, Jer 17 9. Or above all keepings; we must keep our hearts with more care and diligence than we keep any thing else. We must keep our eyes (Job 31 1), keep our tongues (Ps 34 13), keep our feet (Eccl 5 1), but, above all, keep our hearts. 2. A good reason given for this care, because out of it are the issues of life. Out of a heart well kept will flow living issues, good products, to the glory of God and the edification of others. Or, in general, all the actions of the life flow from the heart, and therefore keeping that is making the tree good and healing the springs. Our lives will be regular or irregular, comfortable or uncomfortable, according as our hearts are kept or neglected.

Verses 14-27 The way of evil men may seem pleasant, and the nearest way to compass some end; but it is an evil way, and will end ill; if thou love thy God and thy soul, avoid it. It is not said, Keep at a due distance, but at a great distance; never think you can get far enough from it. The way of the righteous is light; Christ is their Way, and he is the Light. The saints will not be perfect till they reach heaven, but there they shall shine as the sun in his strength. The way of sin is as darkness. The way of the wicked is dark, therefore dangerous; they fall into sin, but know not how to avoid it. They fall into trouble, but never seek to know wherefore God contends with them, nor what will be in the end of it. This is the way we are bid to shun. Attentive hearing the word of God, is a good sign of a work of grace begun in the heart, and a good means of carrying it on. There is in the word of God a proper remedy for all diseases of the soul. Keep thy heart with all diligence. We must set a strict guard upon our souls; keep our hearts from doing hurt, and getting hurt. A good reason is given; because out of it are the issues of life. Above all, we should seek from the Lord Jesus that living water, the sanctifying Spirit, issuing forth unto everlasting life. Thus we shall be enabled to put away a froward mouth and perverse lips; our eyes will be turned from beholding vanity, looking straight forward, and walking by the rule of God's word, treading in the steps of our Lord and Master. Lord, forgive the past, and enable us to follow thee more closely for the time to come.
