Now i dont agree with @Studyman at all in his soteriogly, but I believe though Adam was created innocent and upright, nevertheless he was still mutable flesh at His highest estate and would eventually fall from the high standard of Gods Holy Law which is Spiritual and he was carnal flesh just untried. Rom 7:14
For we know that the law is spiritual: but I am carnal, sold under sin.
Was Adam Spiritual at Creation ? I dont believe so.. Was He natural and carnal ? Yes I believe so, but innocent
What does it mean for a mortal human being to be "Spiritual", or as Paul teaches, "walk in the Spirit"? If the Perfect and most powerful Spirit in existence, my God, tells you not to eat something, and you deny your own hunger, your own desire to eat it, your own reasoning why it should be eaten in every circumstance God places you in, and "Don't eat it", are you not walking in the Spirit and not the flesh?
Remember, a little leaven leavens the whole lump. If I am convinced by other voices in the world God placed me in, that God gives men commandments, but withholds from men the capacity to obey Him, that foundation will influence my every thought. Every Scripture I read will be understood through the prism that God gave Adam and Eve a Law, but withheld from them the capacity to obey because they were created with a "sin nature", or as you say "carnal".
This is the difference between your understanding and mine. I too, believe Adam was created a perfect mortal human being, innocent and upright, with the free will ability to choose God or deny God. They were not created "corrupted", but they were created "corruptible". God didn't "force" them to reject Him or choose Him. He created the circumstance they found themselves in, but HE allowed them to make their own choices. Isn't that the whole point, so that we can learn obedience and walk even as Jesus walked?
Didn't Jesus Blood also provide for their forgiveness, and didn't the Spirit of Christ use their mistake to teach us to Love and honor and "Yield ourselves" to God "lest by any means, as the serpent beguiled Eve through his subtilty, so your minds should be corrupted from the simplicity that is in Christ".
Let me ask you a question, and we will see if you answer. When Adam and Eve made the wrong choice, did God destroy them, or Chastise them?
How is it any different for you and I?
