Whereas believers are described as trichotomous, i.e., as having body life, soul life, and spirit life, I Thess. May your whole spirit, soul and body be kept blameless at the coming of our Lord Jesus Christ. Do not be afraid of those who kill the body but cannot kill the soul. Rather, be afraid of the one who can destroy both soul and body in hell. Psalm 143 states that the soul of the believer is the spiritual combat area.
Authentic misery comes from the soul.
My soul is in anguish. Now that you have purified yourselves by obeying the truth so that you have sincere love for your brothers, love one another deeply, from the heart. Finally, physical death is the departure of the soul from the body. And remember, the real you is your soul. In other words, again, the unbeliever has body life and soul life, but no spirit life.
