Proverbs 3:14

For the merchandise of it [is] better than the merchandise of
silver
The believer is a spiritual merchant; faith is a trading with and for Christ, and for spiritual and heavenly things by him; and because there is a parting with something for Christ, as a man's sinful lusts and pleasures, his own righteousness, his friends and relations, when set in opposition to or competition with him, and even life itself, when called for; and because he runs a risk of suffering reproach, afflictions, and death itself; therefore this concern with him, and enjoyment of him, is called a "merchandise", which is "better than [that] of silver", or than silver which is got by merchandise: for Christ, and the things of Christ, are more valuable than silver, and to be preferred unto it; more useful and profitable than silver is, which a man may have a large abundance of, and lose his soul, whereas by Christ is the salvation of it; more satisfying than silver is, with which a man is never satisfied, whereas he that has Christ has enough, having all things; more pleasant in obtaining, and more safe in enjoying; a great deal of anxiety and vexation attend the one, and inexpressible pleasure the other; and more durable and lasting than that, the enjoyment of Christ is for ever; and the gain thereof than fine gold;
the doctrines and ordinances of Christ are more to be desired than gold, yea, than fine gold; the blessings of grace by Christ, such as redemption, pardon of sin are not obtained by corruptible things, as silver and gold, but are more precious than they; and even the graces of Christ in the hearts of his people, as faith, hope, and love, are more precious than gold that perisheth; and much more preferable must he himself be, and the gain that accrues to a believer by him, which is cent per cent an hundred fold, even in this world, and in the world to come everlasting life: it is all clear gain a believer gets by Christ and trading with him; he has him, and all with him, without money and without price; he has that which is more worth than the gain of the whole world, even the salvation of his immortal soul; the riches he has by Christ are immense and unsearchable, the riches of grace and glory; it cannot be said how great this gain is.
