Studies in Genesis 1
And God said, “Let there be an expanse in the midst of the waters, and let it separate the waters from the waters.” (Genesis 1:6 ESV)
Again, God speaks. Elohim awmar. Every time God speaks His creation responds, conforming to His will and according to His purpose.
Just as when God divided darkness from light so He divides “water” from “water.” Yet, the word He uses for “water” here is the same word He used in Genesis 1:2. He uses this word five times in these three verse.
“Water” does not necessarily mean H2O, which is one of the indispensable molecules needed to sustain life. In Hebrew the word “water” can mean H2O but may mean either urine or semen, or both. When God created matter He talks about both solid and liquid matter. These waters may be the primordial soup of the fantasy theories of those who discount the reality of God’s involvement in creation.
Many theorize life spontaneously erupted from the primordial soup, which is a mixture of chemicals, including methane, ammonia, hydrogen but not oxygen, acted upon by an electrical pulse, heat and ultraviolet light made the chemicals react in a way to form amino acids, which are needed to make protein. Amino acids by themselves are not alive.
Like solid matter brought into existence at creation, “water” is a concoction of stuff hostile to life. God will form “water” into other stuff capable of sustaining life.
He has not yet created. He is making an environment which will sustain the life He is going to make.
