How do I know there is a Soul ? ?

We have Gods word on it

"Soul" occurs 432 times in the KJV

By the Word of God, Who has revealed it to us.

When you die you would see your soul leaving your body, and you would see your body laying down dead with out soul, as being called corpse.

The usual way to *know* something exists (that obviously does not, like souls) is to be indoctrinated as a child into believing it exists.

You don't.  Nothing about a soul has EVER been proven

If the body is animated, it has a soul.  Gen. 2:7

Listen to the Temptations.

With Aretha gone, I am at a loss to explain it. 

Because my feet don't get wet.
