It will be also observed that the episode of the “two witnesses” (chapter xi) falls within the section marked by the trumpet emblem. The appropriateness of this and the ease with which it takes its place here furnish no slight evidence that the explanation of the Revelation adopted in this essay is correct. There are two modes by which the divine Being has chosen to communicate the knowledge of himself and of his will. These are his works and his word. The one is that manifestation of himself in nature of which Paul speaks when he says, “The invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead.” The other is supernatural, the revelation of himself as a power above nature and not limited by its laws. It is of this that Peter says, “We have also a more sure word of prophecy.” The most searching and subtle analysis to which knowledge and its sources have been subjected has resulted in this――that even in the alembic of modern doubt, after the most biting acids have tried their solvent power, there is left as the residuum a conviction that, besides this known and knowable universe, there exists a first cause or force. At the beginning and basis of all things a duality must be acknowledged. If human thought by its unaided light is incompetent to go beyond this, it is not allowed to stop short of it. “The momentum of thought,” Herbert Spencer says, “inevitably carries us beyond conditioned existence to unconditioned existence.” “The certainty that, on the one hand, such a power exists, while, on the other, its nature transcends intuition and is beyond imagination, is the certainty toward which intelligence has been from the first progressing. To this conclusion science inevitably arrives as it reaches its confines.” This power, which science may know only as “an infinite and eternal energy,” is the Being whom the Scriptures reveal to us as the Lord God, of whom and through whom and to whom “are all things: to whom be glory forever.”
