Q. 1. Does the soul ever die?
A. 1. The answer to your question is the soul is immortal. It cannot die. At death, it separates from the body until such time as it is reunited with the body at the final resurrection.
The soul needs a body to express itself. Without a soul, the body is dead. In Heaven, which is a spiritual world, the soul expresses itself through its spiritual form, the ghost or spirit.
