21 Nay more, the whole constitution of nature would bear us out against the impiety of doubting the works and powers of God. And yet our disbelief tilts even against obvious truth; we strive in our fury to pluck even God from His throne. If we could, we would climb by bodily strength to heaven, would fling into confusion the ordered courses of sun and stars, would disarrange the ebb and flow of tides, check rivers at their source or make their waters flow backward, would shake the foundations of the world, in the utter irreverence of our rage against the paternal work of God. It is well that our bodily limitations confine us within more modest bounds. Assuredly, there is no concealment of the mischief we would do if we could. In one respect we are free; and so with blasphemous insolence we distort the truth and turn our weapons against the words of God.
