It appears that you are saying that the Holy Spirit is the law of God put in our hearts and written in our minds.
If so, why are you rejecting and trying to abolish the Holy Spirit?
Jesus who is the epitome of God's holy law indwells Christians by his Spirit.
It is the Spirit of holiness.
God is not going to write the law of Moses on anyones heart that is a Christian. We are called to live by faith, not by rules, laws or religion.
