39. Verse 20 And God said, Let the waters bring forth creeping things, living creatures; and let birds fly above the earth, upon the face ¹ of the expanse of the heavens.

After the great lights have been kindled and lodged in the internal man, from which the external man receives its light, a person starts to live for the first time. Till then he can hardly be said to have lived, for he had imagined that the good he had done he had done from himself, and the truth he had uttered he had spoken from himself. And since man functioning from himself is dead - there being nothing in him that is not evil and false - therefore whatever he brings forth from himself is not living. So true is this that of himself he is incapable of doing any good deed that is in itself good. The fact that man cannot begin to think about good or to will it, and so cannot do good, unless the Lord is the source, is clear to everyone from the doctrine of faith, for the Lord says in Matthew,

He who sows the good seed is the Son of Man. Matthew 13:37.

Nor can good come from anywhere else than the one fount itself of all good, as yet again He says,

Nobody is good but one, God. Luke 18:19.

[2] Nevertheless when the Lord is revitalizing a person, or regenerating him, He does allow him, to begin with, to imagine that good and truth originate in himself, for at that point a person cannot grasp anything else, or be led to believe and finally perceive, that all good and truth come from the Lord alone. As long as he held the former opinion his truths and goods were comparable to 'a tender plant', then 'a plant bearing seed', and after that 'a fruit tree', which are inanimate. But once he has been brought to life by love and faith and believes that the Lord is at work in every good deed he does and in every truth he utters, he is compared first to creeping things from the water and to birds which fly above the earth, and then to beasts, all of which are animate and are called 'living creatures'.

Footnotes:

There are two aspects to the life of each person. We might call them "heart" and "mind," a part of us that wants and feels and a part of us that thinks and knows. The Writings usually refer to these as the "will" and the "understanding." They are reflections, and receptacles, of the Lord's infinite love and infinite wisdom. Of the two, the heart or will is ultimately the most important. Who we actually are is determined by what we love, and the things in our heart ultimately determine our place in heaven (or hell). But the will is beyond our control; we can't force ourselves to want something good or to not want something bad; we can control our actions, but not our feelings. Because of this power, the Lord works subtly and carefully in our hearts, in ways we can't sense. Most of the work and interaction goes on in our minds through the working of what the Writings call "Divine Truth," which is essentially the Lord's entire essence expressed in a form that is compatible with our minds. When the Bible talks about the Lord's "spirit," it represents this operation of Divine Truth in our minds, the way he reaches out and embraces us, and invites us to embrace him back. And when the Bible talks about people having "spirit," it is talking about our minds when we embrace Divine Truth.
