Creation was given to people as a clean window through which the light of God could shine into people's souls. Sun and moon, night and day, rain, sea, the crops, the flowering tree, all these things were transparent. They spoke to people not of themselves but only of Him who made them. Nature was symbolic. But the progressive degradation of humans led them further and further from this truth. Nature became opaque.
Thomas MertonThe whole function of the life of prayer is, then, to enlighten and strengthen our conscience so that it not only knows and perceives the outward, written precepts of the moral and divine laws, but above all lives God's law in concrete reality by perfect and continual union with His will.
