Heaven would be a very hell to an unholy heart. If now – the presence of God in His servants, and the presence of God in His ordinances – is such a hell to unholy souls; ah, what a hell would the presence of God in heaven be – to unholy hearts! It is true, an unholy heart may desire heaven – as it is a place of freedom from troubles, afflictions, oppressions, vexations, etc., and as it is a place of peace, rest, ease, safety, etc. But this is the least and lowest part of heaven. To desire heaven as it is a place of purity, a place of grace, a place of holiness, a place of enjoying God, etc. – is above the reach of an unholy heart. The company of heaven are all holy, the employments of heaven are all holy, the enjoyments of heaven are all holy – therefore heaven would be a most undesirable thing to unholy hearts. An unholy heart is no way desirous nor ambitious of such a heaven as will rid him of his darling sins, as will make him conformable to a holy God, as will everlastingly divorce him from his precious lusts, as will link him forever to those gracious souls whom he has scorned, despised, and persecuted in this world.
