If a person is honest with the scriptures, all of them, not just taking the parable in Luke 16:19ff as a true story, or Jesus' misunderstood statement to the thief on the cross, but taking into account all the OT scriptures that dalk about death, "cut off," sheol, the pit, etc, he'll have a true understanding of what death is.
Why do you think God forbade necromancy, mediums, and other practices where people think they can seek advice from the dead or talk to their dear departed grandma? The devil is responsible for ALL that stuff. Both God and the devil know how gullible people are.
