In The Doctrine of Sanctification, A.W. Pink defines sanctification as the "great promise of the covenant made to Christ for his people" and goes on to say that the promises of God to believers are designed and accomplished to make us holy. To that end, he shows us how to rightly read the Book of Proverbs:
"The supreme excellency of sanctification is affirmed in Proverbs 8:11, 'For wisdom is better than rubies; and all things that may be desired are not to be compared to it.' Everyone who has read the book of Proverbs with any attention must have observed that Solomon meant by "wisdom" holiness, and by "folly" sin; by a wise man a saint, and by a fool a sinner. "The wise shall inhere glory: but shame shall be the promotion of fools" (Prov. 3:35): who can doubt whether by "the wise" he means saints, and by "fools" sinners! "The fear of the LORD is the beginning of wisdom" (Prov. 9:10), by which he means to assert that true "wisdom" is true piety or real holiness. Holiness, then, is "better than rubies", and all things that are to be desired are not to be compared with it."
