Man is tripartite; body, soul and spirit. His body comes from his parents, his spirit comes from God, and his soul, i.e., himself, is the result of this union of body and spirit, a new individual without experience of any kind, but good because made by God Himself. Man is a soul, he possesses a spirit and a body, the former whereby he can contact the spirit world, and the latter with which to enter and appreciate the material world. The soul, if it loses its body, is dead to this world; if it loses its spirit, it is dead to God and the Heavenly world. If it loses both, it is dead to both worlds, conscious only of the isolation and hopeless darkness of death. Gen 2v7—margin "lives," Num 16v22, Isaiah 57v16, Eccl 12v7, I Thess 5v23, Matt 11v11, Heb 4v12, John 3v6, I Cor 2v10-16, Job 10v21-22, Heb 2v15, Luke 12v5.
God, because He is omniscient, from before the foundation of the world knew ALL about EVERY individual that He would create, every thought they would think, every motive and every deed they would do, God knew from before the foundation of the world. Psalm 139 (all).
