Another picture of the results of living in the fear of the Lord. Not that to which it leads a man, but that from which it saves him, is brought into view. Notice also that it is one thing for wisdom to find entrance into the soul, another to be welcomed as a "pleasant" guest.
When wisdom entereth into thine heart,.... Either Christ, the Wisdom of God; who enters there at conversion, and sets up a throne in the heart, and dwells there by faith: or else the Gospel, the wisdom of God in a mystery; which enters not into the head only, as in hypocrites and formal professors; nor into the natural affections, as in the stony ground hearers; but into the heart, opened by the Spirit of God to receive it, so as to have a spiritual understanding of it; which is done when the Gospel comes not in word only, but in the demonstration and power of the Spirit; when a man truly understands it, approves of it, loves it, believes it; and it has a place in his heart, and richly dwells there;
and knowledge is pleasant unto thy soul; which the Gospel thus entering gives; even the knowledge of God in Christ, as the God of all grace, as gracious and merciful, forgiving iniquity, transgression, and sin; the knowledge of Christ, as the only Redeemer and Saviour; and the knowledge of Gospel truths, which lead and relate unto him: all which is pleasant to a gracious soul, and affords unspeakable delight to the mind; and is sweeter, as every truth of the Gospel is, than the honey or the honeycomb; see Proverbs 16:24.
If we are truly wise, we shall be careful to avoid all evil company and evil practices. When wisdom has dominion over us, then it not only fills the head, but enters into the heart, and will preserve, both against corruptions within and temptations without. The ways of sin are ways of darkness, uncomfortable and unsafe: what fools are those who leave the plain, pleasant, lightsome paths of uprightness, to walk in such ways! They take pleasure in sin; both in committing it, and in seeing others commit it. Every wise man will shun such company. True wisdom will also preserve from those who lead to fleshly lusts, which defile the body, that living temple, and war against the soul. These are evils which excite the sorrow of every serious mind, and cause every reflecting parent to look upon his children with anxiety, lest they should be entangled in such fatal snares. Let the sufferings of others be our warnings. Our Lord Jesus deters from sinful pleasures, by the everlasting torments which follow them. It is very rare that any who are caught in this snare of the devil, recover themselves; so much is the heart hardened, and the mind blinded, by the deceitfulness of this sin. Many think that this caution, besides the literal sense, is to be understood as a caution against idolatry, and subjecting the soul to the body, by seeking any forbidden object. The righteous must leave the earth as well as the wicked; but the earth is a very different thing to them. To the wicked it is all the heaven they ever shall have; to the righteous it is the place of preparation for heaven. And is it all one to us, whether we share with the wicked in the miseries of their latter end, or share those everlasting joys that shall crown believers?
Idea of Proverbs 2:9, amplified; on terms, compare Proverbs 2:2 and Proverbs 2:4.
