The will maketh the beginning, the middle, and the end of everything; it is the only workman in nature, and everything is its work.  It has all power, its works cannot be hindered, it carries all before it, it creates as it goes and all things are possible to it.  It enters whenever it wills and finds everything that it seeks, for its seeking is its finding.  The will overrules all nature, because nature is its offspring and born of it; for all the properties of nature, whether the be good or evil, in darkness or in light, in love or in hatred, in wrath or in meekness, in pride or humility, in trouble or birth of the will; as that liveth so, they live, and as that changeth, so they change.

William Law: Divine Knowledge.
