** The spirit drives the soul that drives the body that sins..
The spirit also accepts Christs sacrifice and covering..
The spirit can be re-born.. regenerated.. forgiven as a prodigal son to a spiritual father..
The human body is concieved by a man and woman as in all animals and is indeed that bodys Father and Mother, the spirit is added by the heavenly father... and is the father to the spirit.. all of them(spirits).. whether they agree with that or NOT..
Most humans do not know they are indeed spirits in a body suit..
That was pretty much Jesus' ministry to inform them of that.. in a way they could accept.. (some of them)..
The brain is not the soul. Life is the soul.
God created man body+soul (in that order). Our "natural" state, therefore, is body & soul, not just the "naked" soul.
