“In treating of heaven it has been every where shown that the Lord is the God of heaven, thus that all the government of the heavens is in the hands of the Lord; and since the relation of heaven to hell, and of hell to heaven, is as that between two opposites, which act contrary to each other, from whose action and reaction results an equilibrium in which all things abide, therefore in order that things one and all may be kept in equilibrium, it is necessary that He who rules the one should also rule the other; for unless the same Lord restrained the uprisings from the hells and checked the insanities there, the equilibrium would perish and with the equilibrium the whole.”
