Our weekly installment from Gurnall reminds us where our treasure lies.

The chief prize for which we wrestle against Satan is heavenly. Or thus, Satan’s main design is to spoil and plunder the Christian of all that is heavenly. Indeed, all the Christian hath, or desires as a Christian, is heavenly. The world is extrinsical, both to his being and happiness, it is a stranger to the Christian, and intermeddles not with his joy or grief. Heap all the riches and honours of the world upon a man, they will not make him a Christian; heap them on a Christian, they will not make him a better Christian. Again, take them all away . . . when stripped and naked, he will still be a Christian, and may be a better Christian. . . . Satan should do the saint little hurt, if he did bend his forces only or chiefly against his outward enjoyments. Alas, the Christian doth not value them, or himself by them; this were as if one should think to hurt a man by beating of his clothes when he hath put them off. So far as the Spirit of grace prevails in the heart of a saint, he hath put off the world in the desire of it and joy in it, so that these blows are not much felt; and therefore they are his heavenly treasures, which are the booty Satan waits for.
