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 Pro 16:24.
