Genesis 1.3.5

And God said, let there be light: and there was light. And God saw the light, that it was good: and God divided the light from the darkness.  And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day.

The most intriguing part is the introduction of the light, and how it merely repels the darkness; there's even a hint that light comes from darkness.

Unfortunately, the constant use of the word light is a dead give away; one of the guides to writing well is to stay away from the constant use of a single word by using synonyms or pronouns to clarify and expand its nature and definition.  What happened to the Spirit?

The Spirit isn't mentioned again until Genesis 6.3 and only as a thing; definitely cause for concern.  Keeping this in mind, in order to keep the light sacred, God, or the Spirit, divided the light from the darkness by transforming them both into separate and distinct entities, the capitalization of Day and Night.  For some reason, both light and darkness must be sustained, which raises the question why? Why give it power?  Why not abolish it all together or leave it as it is? Unless God was powerless against it; perhaps the Spirit limited God out of responsibility.

The last line implies the process takes time; the stanza should be developed more to bring out these implications; also, a decision needs to be made regarding the Spirit.  If the Spirit has limited God's power then it's safe to assume the Spirit would want to oversee the healing of earth before returning to its origins.  So for the time being, I'll include the Spirit in the seven days of creation, or healing as it were.  Since God was overshadowed by his creation; the Spirit provides the light.  Water.darkness.light. 

The Spirit said: let there be light.  In a cacoon of glory, God saw the flame of salvation, yet was not relieved of sadness.  So be it.  Dawn shall be divided from Dusk, Day from Night, and the evening and morning were the first day.
