Hi James - Myself, I see the eradication concept conflicting with a multitude of scriptural doctrine (no contention towards you), esp. with Galatians 5:17: "For the flesh lusts against the Spirit, and the Spirit against the flesh; and these are contrary to one another, so that you do not do the things that you wish."
To me, this is a description of the Adamic nature ("old man") and the Holy Spirit co-existing (not cohabitation) within the believer and I think it would require quite a fanciful aspiration (not accusing you) for anyone to explain it otherwise.
There remains also the lack of an explanation for the phrase "so that you do not do the things that you wish;" which implies the ongoing tendency for the believer to do wrong, evincing the presence of the sin nature. I also believe Scripture would be more clear in identifying it's death in like manner as it has concerning our death in Christ, i.e., "For you died, and your life is hidden with Christ in God" (Col 3:3).
Blessings to your Family!
I agree. Sin and satan is in our flesh.. we don't get rid of that until we die.. the Spirit of God is in our spirit.. the human mind is a good part of us that needs to be set on the Spirit. Christ got rid of his Adamic nature by dying on the cross..but we don't get rid of ours until we also die... but actually the Spirit of Christ within us contains all the elements of Christ's human life, death and resurrection therefore in our spirit we are dead to the Adamic nature...but in our flesh it is still present.
