The bible is clear about the triune nature of man... body and soul and spirit. Just as the bible is clear about the Triune nature of God.Heres where you got this wrong....You & I & others who accept CHRIST are body soul & SPIRIT
Those who don't are missing the one part of this and that being the SPIRIT if your not of CHRIST your spirit is dead the body is winding down to that death where your soul will also go seperated from GOD (that is spiritual death being seperated from GOD)
God's spirit is known as the Holy spirit.
Much can be said about the Holy spirit but let God speak...
Not by might nor by power, but by My Spirit, says the LORD of Hosts.
