When the fall happened, sin caused the body to fall and have a tainted soul, a dead spirit, a carnal flesh and a God shaped hole where the Holy Spirit would dwell. The Holy Spirit could not live in a tainted soul because he is Holy. The Holy Spirit had to purify the soul by repentance to bring life into the spirit. With repentance we receive heaven's gift, before the sacrifice of Jesus the God shaped hole couldn't be filled but the Holy Spirit rested upon men. Then later after Jesus gave up his life as a sacrifice and then man could be clean by the dependance of the Holy Spirit. The Holy Spirit heals the body and keeps it clean. It suppresses the flesh and keeps the spirit alive as a new creation and the soul is clean. In heaven the flesh is new and not carnal. It is crucified fully. We receive a new body without messed up flesh when we go to heaven. The crucified flesh has become new flesh. The uncrucified flesh is what the Spirit crucifies through repentance and grace rules over the body and the countenance is the glory that aids man in repentance. It judges sin and makes testimony so that others: angels, man or God can help bring others into repentance.
The mind, emotions and will are a part of the spirit and flesh. With a new spirit we can detect through the eyes of the Holy Spirit. The spirit and flesh can both have different body parts are separated by the word of God and what you feed is what is developed. Deliverance help heal the body and crucify the flesh from blocking the spirit.
