The terms soul and spirit have been discussed at length throughout philosophy, literature, and religion. Even scientists have ventured remarks about the soul. Often, though, soul and spirit are interpreted to mean the same thing and end up being used interchangeably.
This can lead to the question: ‘Is there a difference between the soul and the spirit, and does it really matter if there is?’

So what does God’s Word say about our soul and our spirit? And why can knowing this be a crucial factor in our spiritual progress and relationship with God?
