Now consider, I pray you: the light and spirit of this world can no more be the Light and Spirit of immortal Souls, than grass and hay can be the food of angels; but is as different from the Light and Spirit of Heaven, as an angel is different from a Beast of the field. When therefore the soul of a man departs from his body, and is eternally cut off from all temporal light and spirit, what is it that can keep such a soul from falling into eternal darkness, unless it have in itself, that Light and Spirit, which is of the same nature with the Light and Spirit of Eternity, so that it may be in the Light of Heaven or Eternal Nature, as it was in the Light of this world in temporary nature.
Light and Spirit there must be in every thing that lives, but the death of the body takes away the light and spirit of this world; if therefore the Light and Spirit of Heaven be not born in the soul when it loses the body, it can only have that light and spirit, which is the very death and darkness of Hell.
When man lost the Light and Spirit of his creation, he lost it by turning the will and desire of his soul into an earthly life; this was his desire of knowing good and evil in this world. His fall therefore consisted in this, his soul lost its first innate, in-breathed Light and Spirit of Heaven, and instead of it, had only the light and spirit of temporary nature, to keep up for a time such a life in him from this world, as the proper creatures of this world have: And this is the reason, why man, the noblest creature that is in this world, has yet various circumstances of necessity, poverty, distress and shame, that are not common to other animals of this world. Tis because the creatures of this life are here at home, are the proper inhabitants of this world, and therefore that womb out of which they are born, has provided them with all that they want; but man being only fallen into it, and as a transgressor, must in many respects find himself in such wants as other creatures have not. Transitory time has brought them forth, and therefore they can have no pain, nor concern, not danger in passing away; because it is the very form of their nature, to begin, and to have an end: And therefore the God of Nature has no outward Laws, or directions for the creatures of this world.
But the soul of man being not born of the light and spirit of this transitory world, but only standing a while as a stranger upon Earth, and being under a necessity of having either the nature of an Angel, or a Devil, when it leaves this world, is met by the mercy and goodness of the God of nature, is inwardly and outwardly called, warned, directed, and assisted how to regain the Light and Spirit of Heaven which it lost, when it fell under the temporary light and spirit of this world. And this is the whole ground and end of revealed religion, viz., to kindle such a beginning or birth of the Divine Light and Spirit in the soul, that when man must take an eternal leave of the light and spirit of this world, he may not be in a state of eternal death and darkness.
