Power might as Omnipotence.

“The immense mountains and precipices that overhung me on every side—the sound of the river raging among the rocks, and the dashing of the waterfalls around, spoke of a power mighty as Omnipotence—and I ceased to fear, or to bend before any being less almighty than that which had created and ruled the elements, here displayed in their most terrific guise.” (Shelley 49).

The narrator here is moved by the sublime elements in the spectacular sight he is viewing—that of Nature. Nature here is described as “omnipotent,” or all knowing—it is a force greater than Frankenstein, even though he did create life. This connection and theme is restated many times throughout the novel.
