The soul, the will causes blessings. The soul leaves as we die. But take diligent heed to do the commandment and the law, which Moses the servant of the LORD charged you, to love the LORD your God, and to walk in all his ways, and to keep his commandments, and to cleave unto him, and to serve him with all your heart and with all your soul. The soul desires. The soul and the spirit are not always on the same level.
Deliverance is of the soul.
It is not the spirit, but the soul that makes choices, and gets in doubt. Out of the soul come praises and cursing. Out of the spirit only comes praising, and the flesh cursing. The soul and the spirit connected working together, for the belly is where the spirit is. The soul is fed.
