Whatever is revealed it becomes us to believe, and simply on this account, that it _is revealed_; if the subject of the revelation be mysterious or incomprehensible, this does not annul our obligation implicitly to believe it, because sufficient reasons may exist in the Eternal Mind for the concealment of its nature, or it may surpass the comprehension of our limited capacities; but if it be naturally capable of investigation--if it be not only a fact, but a fact in proof of which evidences may be adduced, and explanations furnished, our minds cannot be better employed, than in thus superinducing substantial evidence or vivid probability upon the testimony of divine inspiration. I. It is highly reasonable to suppose, that there are beings of a distinct and superior order to ourselves in the universe. Nothing can be more improbable than to imagine that this earth is the only inhabited region of universal empire, the only peopled province in the creation of God; especially when we observe that it forms but one, and that a small globe of matter belonging to a system in which others, and some very superior bodies, are found moving round the came centre, and legulated by similar laws; and that this whole system itself is but one out of ten thousand others that constitute the heavenly constellations, and "pave the shining way to the divine abode." The productions of Infinite Wisdom are wonderfully diversified. In the present world we have an opportunity of observing them only in the descending scale, from man, the summit of creation, down through all the gradations of animal existence, to the scarcely discernible insects that flit in the summer sunbeams, and to the minuter world of microscopic discovery. But analogy would lead us to infer, that there may be beings in the vast dominion of universal space as much superior to man as man himself is superior to insects or animalculæ. It is not probable that creative power should cease to operate precisely at the point where human existence commences; and especially as _mind_ admits of incalculable diversity in the extent of its energies and capacities, and as it is found in all cases to possess a power of improvement and expansion, it is likely, under other circumstances and in other worlds, it may he inconceivably superior to the highest elevation it his ever attained in this lower region. Hence we infer the great probabilily of angelic existence.
