Can the soul and spirit function without a body?
No. Scripture never presents a human being operating without a body; the soul and spirit by themselves do not operate as an entity but must have a body. Believers await a changed body, fashioned like unto Christ's glorious body.
Les explains that never in Scripture does the human being operate without a body. The soul and spirit by itself does not operate as an entity; it has to have a body. He connects this to the eternal state, where our citizenship is in heaven. As believers, we look for the Savior, the Lord Jesus Christ, who shall change our vile body and fashion it like unto His glorious body, according to the working whereby He is able even to subdue all things unto Himself.
