When, then, we think to take part in the joys of heaven without holiness, we are as inconsiderate as if we supposed we could take an interest in the worship of Christians here below without possessing it in our measure. A careless, a sensual, an unbelieving mind, a mind destitute of the love and fear of God, with narrow views and earthly aims, a low standard of duty, and a benighted conscience, a mind contented with itself, and unresigned to God's will, would feel as little pleasure, at the last day, at the words, "Enter into the joy of thy Lord," as it does now at the words, "Let us pray." Nay, much less, because, while we are in a church, we may turn our thoughts to other subjects, and contrive to forget that God is looking on us; but that will not be possible in heaven.
We see, then, that holiness, or inward separation from the world, is necessary to our admission into heaven, because heaven is not heaven, is not a place of happiness except to the holy. There are bodily indispositions which affect the taste, so that the sweetest flavours become ungrateful to the palate; and indispositions which impair the sight, tinging the fair face of nature with some sickly hue. In like manner, there is a moral malady which disorders the inward sight and taste; and no man labouring under it is in a condition to enjoy what Scripture calls "the fulness of joy in God's presence, and pleasures at His right hand for evermore."
Nay, I will venture to say more than this;—it is fearful, but it is right to say it;—that if we wished to imagine a punishment for an unholy, reprobate soul, we perhaps could not fancy a greater than tosummon it to heaven. Heaven would be hell to an irreligious man. We know how unhappy we are apt to feel at present, when alone in the midst of strangers, or of men of different tastes and habits from ourselves. How miserable, for example, would it be to have to live in a foreign land, among a people whose faces we never saw before, and whose language we could not learn. And this is but a faint illustration of the loneliness of a man of earthly dispositions and tastes, thrust into the society of saints and angels. How forlorn would he wander through the courts of heaven! He would find no one like himself; he would see in every direction the marks of God's holiness, and these would make him shudder. He would feel himself always in His presence. He could no longer turn his thoughts another way, as he does now, when conscience reproaches him. He would know that the Eternal Eye was ever upon him; and that Eye of holiness, which is joy and life to holy creatures, would seem to him an Eye of wrath and punishment. God cannot change His nature. Holy He must ever be. But while He is holy, no unholy soul can be happy in heaven. Fire does not inflame iron, but it inflames straw. It would cease to be fire if it did not. And so heaven itself would be fire to those, who would fain escape across the great gulf from the torments of hell. The finger of Lazarus would but increase their thirst. The very "heaven that is over their head" will be "brass" to them.
