It is essential to the understanding of Law, as of Boehme, to remember his belief in the reality and actuality of the oneness of nature and of law.[40] Nature is God’s great Book of Revelation, for it is nothing else but God’s own outward manifestation of what He inwardly is, and can do....  The mysteries of religion, therefore, are no higher, nor deeper than the mysteries of nature.[41] God Himself is subject to this law.  There is no question of God’s mercy or of His wrath,[42] for it is an eternal principle that we can only receive what we are capable of receiving; and to ask why one person gains no help from the mercy and goodness of God while another does gain help is “like asking why the refreshing dew of heaven does not do that to the flint which it does to the vegetable plant."[43]

Self-denial, or mortification of the flesh is not a thing imposed upon us by the mere will of God:  considered in themselves they have nothing of goodness or holiness, but they have their ground and reason in the nature of the thing, and are as “absolutely necessary to make way for the new birth, as the death of the husk and gross part of the grain is necessary to make way for its vegetable life."[44]

These views are clear enough, but the more mystical ones, such as those which Law and Boehme held, for instance, about fire, can only be understood in the light of this living unity throughout nature, humanity, and divinity.

“Everything in temporal Nature,” says Law, “is descended out of that which is eternal, and stands as a palpable, visible Outbirth of it:  ...  Fire and Light and Air in this World are not only a true Resemblance of the Holy Trinity in Unity, but are the Trinity itself in its most outward, lowest kind of Existence or Manifestation....  Fire compacted, created, separated from Light and Air, is the Elemental Fire of this World:  Fire uncreated, uncompacted, unseparated from Light and Air, is the heavenly Fire of Eternity:  Fire kindled in any material Thing is only Fire breaking out of its created, compacted state; it is nothing else but the awakening the Spiritual Properties of that Thing, which being thus stirred up, strive to get rid of that material Creation under which they are imprisoned ... and were not these spiritual Properties imprisoned in Matter, no material Thing could be made to burn....  Fire is not, cannot be a material Thing, it only makes itself visible and sensible by the Destruction of Matter."[45] “If you ask what Fire is in its first true and unbeginning State, not yet entered into any Creature, It is the Power and Strength, the Glory and Majesty of eternal Nature....  If you ask what Fire is in its own spiritual Nature, it is merely a Desire, and has no other Nature than that of a working Desire, which is continually its own Kindler.” [46]

All life is a kindled fire in a variety of states, and every dead, insensitive thing is only dead because its fire is quenched or compressed, as in the case of a flint, which is in a state of death “because its fire is bound, compacted, shut up and imprisoned,” but a steel struck against it, shows that every particle of the flint consists of this compacted fire.
