The fear of the Lord is his treasure. Isa. 32:6.
But doubtless there are some hypocrites, that have only false affections, who will think they are able to stand this trial; and will readily say, that they desire not to rest satisfied with past attainments, but to be pressing forward, they do desire more, they long after God and Christ, and desire more holiness, and do seek it. But the truth is, their desires are not properly the desires of appetite after holiness, for its own sake, or for the moral excellency and holy sweetness that is in it; but only for by-ends. They long after clearer discoveries, that they may be better satisfied about the state of their souls; or because in great discoveries self is gratified, in being made so much of by God, and so exalted above others; they long to taste the love of God (as they call it) more than to have more love to God. Or, it may be, they have a kind of forced, fancied, or made longings; because they think they must long for more grace, otherwise it will be a dark sign upon them. But such things as these are far different from the natural, and as it were necessary appetite and thirsting of the new man, after God and holiness. There is an inward burning desire that a saint has after holiness, as natural to the new creature, as vital heat is to the body. There is a holy breathing and panting after the Spirit of God, to increase holiness, as natural to a holy nature, as breathing is to a living body. And holiness or sanctification is more directly the object of it, than any manifestation of God’s love and favor. This is the meat and drink that is the object of the spiritual appetite: Where we read in Scripture of the desires, longings, and thirstings of the saints, righteousness and God’s laws are much more frequently mentioned as the object of them, than anything else. The saints desire the sincere milk of the word, not so much to testify God’s love to them, as that they may grow thereby in holiness. I have shown before, that holiness is that good which is the immediate object of a spiritual taste. But undoubtedly the same sweetness that is the chief object of a spiritual taste, is also the chief object of a spiritual appetite. Grace is the godly man’s treasure. Hypocrites long for discoveries more for the present comfort of the discovery, and the high manifestation of God’s love in it, than for any sanctifying influence of it. But neither a longing after great discoveries, or after great tastes of the love of God, nor longing to be in heaven nor longing to die, are in any measure so distinguishing marks of true saints, as longing after a more holy heart, and living a more holy life.
