As I claim in my book, Adam before his fall was an effective computer. “Sin” mean inefficiency. With Adam fall we become inefficient.
Salvation by Christ means that we become efficient again. We are already saved what means we became efficient again (even despite we do not see ourselves as powerful computers). When God looks to us through Christ, He sees efficient machines.
If you have no leg or no hand, in my opinion, it is unlikely that it will grow back. What then (Is. 53:5) “and by his wounds we are healed” and (1Pet. 2:24) “that we, having died to sins, might live to righteousness; by whose stripes you were healed” means? It claims that we are already healed!
This means that we received Holy Spirit as a prosthesis. Unlike human-made prostheses, Holy Spirit is better that our natural body parts. This means that through Holy Spirit we are more effective in some deeds than Adam was before his fall. And this deed is to be children of God, the peacemakers (see my book) of His kingdom.
On the Earth as a result of this, we are blessed that is effective in our life again. We get blessed not accordingly our sinful nature but accordingly Holy Spirit.
And remember that faith that we are already healed in Christ produces our natural healing. God’s living prostheses cause our natural body to be repaired.
