Adam and Eve's souls were created (bara) at the same time in Genesis 1:27. They were created (bara) out from nothing.
Its the body which was not created (bara), but was made from what had already been created, was technically produced at the same time. For the exact same substance for Adam's body was the same for the woman. It had been removed from Adam's body. They shared the same body separately... For they were "one flesh."
Actually, Genesis 1:27 doesn't seem to imply that God created Adam and Eve's souls exclusively, but rather Psalm 139:16.
So God created SOULS (after sentience like him), and then the template system for the capacity of reproduction and roles afterwards-- which has nothing to DO with the soul specifically (like in James 1 and 2, gender here would only be 'inadvertently' referenced). I don't have BW installed on my system since it was re-imaged to Windows 8.1 (which I had to install twice):
Gen 1:27 So God created man in his own image, in the image of God created he him | *space* | male and female created he them.
There's a lot to this actually (because it's implying God foreknew the fall of man--of course He did-- but if man didn't fall
and that was always a possibility, then those souls would have to be reallocated somewhere else after Adam would have completed the angelic trial). Which is most likely what would have happened, since God would have always had 'us' in mind even if Adam didn't fall.
Genesis 1:27 from my observations looks to be agnostic from explicitly referring to Adam & Eve but to all of humanity. Because Adam and Eve didn't have their souls active yet, and when their bodies were finally created Adam was first. So then it would be impossible for gender to have a space here... since gender was not yet associated to the souls. And here's the kicker, if God had all souls in mind, and Adam DIDN'T fall, then it would be *impossible* for the souls to be keyed to gender, as the other sons--us who came after adam--would probably not be in a genderized body.
Now what God *does* do is figure out the variables and impute a soul to whichever gender *best suits* the soul (which is where we get into the 'inadvertently' referencing gender). The best way for someone to figure that out is to see what God has provisioned in their life, and what He wants you to do. There's situations where everyone
violates their roles; and often it is done out of not having Bible Doctrine in your frontal lobe, so you LOSE freedom since without doctrine, you're barely aware of what's happening).
God creating Eve from Adam is purely for a concept for us to think about, it has nothing to do with souls in Genesis 1:27 directly. It would be like saying God re-using the TOHUWABOHU earth is somehow related to our souls. Not really. The concept implies God using what's there-- of course this is changed when the lake of fire and new jerusalem are created from scratch and all of the 'old world' is *completely* burned up. God using biological hierarchy wouldn't have a direct effect on the soul's independence. It would actually be unjust for God to do, as he'd be hard-coding a soul with no choice. Whereas if God gives you a body based on what He thinks is best contoured to you, is upholding your freedom.
