And, accordingly, reasoning from the identity of truth, which is the same above as it is below, we cannot hesitate in saying, that love is the life of heaven, as it is of earth. And such is the nature of love, that it must have objects there, as it has here. It must have its laws there, as it has here. It must have its great centre and also its subordinate centers there, as it has here. It must fulfill its own ends and grow up into society there, as it does here. To be in heaven, and not to be in the exercise of love, is a contradiction. Angels have their loves; — and heaven, if they were not allowed to exercise their benevolent affections there, and to group themselves together in bright clusters, in accordance with the constitutive and eternal laws of moral beings, would cease to be heaven to them, and would become a place of sorrow. And it is one of the consolations which God allows us in the present state, in being permitted to believe that the wants of the heart here will be met and solaced hereafter; — that those suffering, but holy, ones, who have been smitten and robbed in the rights of the affections here, will find kindred spirits, (celestial stars, as it were, reflecting their own brightness,) who will mast and embrace them, and will wipe away their tears at the threshold of the New Jerusalem.
