Studies in Genesis 1
In the beginning, God created the heavens and the earth. The earth was without form and void, and darkness was over the face of the deep. And the Spirit of God was hovering over the face of the waters. And God said, “Let there be light,” and there was light. And God saw that the light was good. And God separated the light from the darkness. God called the light Day, and the darkness he called Night. And there was evening and there was morning, the first day. (Genesis 1:1-5 ESV)
God created the universe as a closed system, and all of the material found in the universe ex nihilo, out of nothing. As a closed system nothing can be added nor taken from the universe. He established the Laws of the universe determining all creation adhere to those Laws. God exists outside of the universe and all He created.
His Spirit moved throughout the created universe, through the darkness, over the waste. He is active and mindful of all His creation. He has absolute control.
God then took the material He created and shaped and formed it into other things.
God spoke. When God speaks He assigns purpose and direction. Out of the existing material of the universe He made “light” which is energized matter moving at a high speed. God approved of light.
God separated light from darkness, beginning the process of building a place where life can exist and grow. God separates that which He deems “good” as measured according to His eternal standards from that which just is. Yet, He takes that which just is and shapes it according to His will. His first act of separating is light from darkness.
He called the light “Day.” Day means a period of time of light. With light comes life.
He called the darkness “Night.” Night means a period of time of darkness. With darkness is waste and desolation.
Everything God creates is perfect, fitting His design and specifications.
