At the point of death the soul of man goes to the spiritual abode of the dead. Eternal life or Eternal damnation. Old Testament picture of “Abraham’s bosom”.
Draw a circle and draw a line through the middle. The picture is Paradise which is divided into Heaven or Hell. The unseen world.
Redeemed saints receive Heaven’s Bliss. Those lost men and women are without redemption receive Eternal Damnation like Jesus spoke of in Luke 16 concerning Lazarus and the rich man.
The physical bodies of the redeemed or lost always go to the grave (a place and physical abode of the body until it returns to dust).
The word Hell in the Old Testament (Sheol) is often interpreted the grave (where the physical body is placed) and what takes place at the point of death.
