“There was a rich man who was dressed in purple and fine linen and lived in luxury every day. At his gate was laid a beggar named Lazarus, covered with sores and longing to eat what fell from the rich man’s table. Even the dogs came and licked his sores.
“The time came when the beggar died and the angels carried him to Abraham’s side. The rich man also died and was buried. In Hades, where he was in torment, he looked up and saw Abraham far away, with Lazarus by his side. So he called to him, ‘Father Abraham, have pity on me and send Lazarus to dip the tip of his finger in water and cool my tongue, because I am in agony in this fire.’
“But Abraham replied, ‘Son, remember that in your lifetime you received your good things, while Lazarus received bad things, but now he is comforted here and you are in agony. And besides all this, between us and you a great chasm has been set in place, so that those who want to go from here to you cannot, nor can anyone cross over from there to us.’
“He answered, ‘Then I beg you, father, send Lazarus to my family, for I have five brothers. Let him warn them, so that they will not also come to this place of torment.’
“Abraham replied, ‘They have Moses and the Prophets; let them listen to them.’
“‘No, father Abraham,’ he said, ‘but if someone from the dead goes to them, they will repent.’
“He said to him, ‘If they do not listen to Moses and the Prophets, they will not be convinced even if someone rises from the dead.’”
(Luke 16:19-31 NIV)
a couple of interesting things to note here about, because we're talking about a man who has died in the flesh and also does not have life in Christ -- so qualifies as 'dead' both in the physical & spiritual sense
- the dead still have personhood
- the dead still have existence and are cogent
- the dead can 'look up' - they have eyes
- the dead have tongues
- the dead can be tormented
- the dead can experience agony
- the dead can desire water
- the dead can communicate
- the dead remember their past and their family
- the dead have emotion
someone offended by what is written here may come along and say 'this only is a parable, it's not real' -- but you may answer them, saying, Jesus does not call it a parable, gives no indication it is a parable at all, Jesus does not use proper names in any parable but says 'a certain man..' etc, and even if it were a parable rather than a true event, Jesus does not use lies and false, impossible situations in order to teach. everything in this is accurate and true representation or else you make Christ a liar.
put together all the faculties this dead man has, and i think we have a clear picture that the soul/mind/spirit persist after the death of the body. this proves the eternal existence of the person, beyond death - both physical and spiritual death - and proves that the physical body is not the person, but the non-physical is.
