When we are Born Again of the Holy Spirit we are made a New Spirit being who is In Christ and incorruptible.
The Soul and the Body are still corrupted until the day that they are Transformed at the Return of Jesus.
Sin is an issue to the Soul, Body and Society but it is not an issue with God. Sin was dealt with once and for all in the Sacrifice of Christ Jesus.
The Law of Spirit Of Life is the Law that underpins Salvation by Grace Through Faith in Christ Jesus.
There is no comparison between the Law of Spirit Of Life and the Law of Sin And Death.
The Spirit Of Life is the Holy Spirit is the Spirit Of Christ Jesus who is our Eternal Life by virtue of us being One with Christ by His indwelling Spirit.
