Proverbs 3:18-20
18 She is a tree of life to them that lay hold upon her: and happy is every one that retaineth her.
19 The Lord by wisdom hath founded the earth; by understanding hath he established the heavens.
20 By his knowledge the depths are broken up, and the clouds drop down the dew.
3. It is the happiness of paradise (Prov. 3:18): She is a tree of life. True grace is that to the soul which the tree of life would have been, from which our first parents were shut out for eating of the forbidden tree. It is a seed of immortality, a well of living waters, spring up to life eternal. It is an earnest of the New Jerusalem, in the midst of which the tree of life, Rev. 22:2; 2:7). Those that feed and feast on this heavenly wisdom shall not only be cured by it of every fatal malady, but shall find an antidote against age and death; they shall eat and live forever.
4. It is a participation of the happiness of God himself, for wisdom is his everlasting glory and blessedness, Prov. 3:19-20. this should make us in love with the wisdom and understanding which God gives, that the Lord by wisdom founded the earth, so that it cannot be removed, nor can ever fail of answering all the ends of its creation, to which it is admirably and unexceptionably fitted. By understanding he has likewise established the heavens and directed all the motions of them in the best manner. The heavenly bodies are vast, yet there is no flaw in them—numerous, yet no disorder in them—the motion rapid, yet no wear or tear; the depths of the sea are broken up, and thence come the waters beneath the firmament, and the clouds drop down the dews, the waters from above the firmament, and all this by the divine wisdom and knowledge; therefore happy is the man that finds wisdom for he will thereby be thoroughly furnished for every good word and work. Christ is made that Wisdom, by whom the worlds were made and still consist; happy therefore are those to whom he is made of God wisdom, for he has wherewithal to make good all the foregoing promises of long life, riches, and honour; for all the wealth of heaven, earth, and seas, is his.
