And Hank, notice that 1 Cor 15:22 says that in Adam all "die". It does not say in Adam all are "dead". That is a very important distinction, you must first be alive to die.
But... this verse is speaking of physical death, not spiritual death to begin with.
So, those who argue that 1 Cor 15:22 says men are born spiritually dead in Adam's sin err.
You are correct about one thing - I'm not convinced of your position because of scripture, namely these two verses Romans 5:12 and 1 Corinthians 15:22.
To me, the resurrection of which 1 Corinthians 15:22 speaks is all encompassing, it is unto eternal life and delivers from that which we received from Adam (Romans 5:12).
In my view death is all one package received from our progenitor Adam.
And yes, I remember as a child going to church, carefree and untroubled by my conscience, firmly believing that God loved and heard me.
The wrongs that I had done seemed not to be so wrong.
It was in the military, I began reading the Bible. Genesis was fine but Exodus and Leviticus "killed" me, destroyed my connection with God.
A year or so later I received Christ and returned to that position I felt in my childhood. But that is "feelings" and not Scripture.
Of course there was much more to come as I grew spiritually.
I believe that the teaching of the scripture (Romans 5:12) is that we become what we are because it was passed on to us as the children of Adam. True, we put our stamp of approval on what we are by committing our own repetoir of sins.
I'm not convinced of the anaysis of Romans 5:12 you gave. It seems clear to me that the teaching is we enter this world "in Adam".
1 Corinthians 15:22 For as in Adam all die, even so in Christ shall all be made alive.
Good point though, "die" is present indicative. I'll think on that.
Thanks
