“Nature is God's Will and is its expression in and through the contingent world.”

Say: Nature in its essence is the embodiment of My Name, the Maker, Creator. Its manifestations are diversified by varying causes, and in this diversity there are signs for men of discernment. Nature is God's Will and is its expression in and through the contingent world. It is a dispensation of Providence ordained by the Ordainer, the All-Wise.
