Here then, is mathematical demonstration that it is not in the power of any being to originate matter. Hence we conclude that matter as well as spirit is eternal, uncreated, self-existing. However infinite the variety of its changes, forms and shapes;--however vast and varying the parts it has to act in the great theatre of the universe;--whatever sphere its several parts may be destined to fill in the boundless organization of infinite wisdom, yet it is there, durable as the throne of Jehovah. And Eternity is inscribed in indelible characters on every particle. Revolution may succeed revolution,--vegetation may bloom and flourish, and fall again to decay in the revolving seasons--generation upon generation may pass away and others still succeed--empires may fall to ruin, and moulder to the dust and be forgotten--the marble monuments of antiquity may crumble to atoms and mingle in the common ruin--the mightiest works of art, with all their glory, may sink in oblivion and be remembered no more--worlds may startle from their orbits, and hurling from their spheres, run lawless on each other in conceivable confusion--element may war with element in awful majesty, while thunders roll from sky to sky, and arrows of lightning break the mountains asunder--scatter the rocks like hailstones--set worlds on fire, and melt the elements with fervent heat, and yet not one grain can be lost--not one particle can be annihilated. All these revolutions and convulsions of nature will only serve to refine, purify, and finally restore and renew the elements upon which they act. And like the sunshine after a storm, or like gold seven times tried in the fire, they will shine forth with additional lustre as they roll in their eternal spheres, in their glory, in the midst of the power of God.
