They have a body (the flesh) and a spirit (ruach OT and pneuma NT). The spirit is the life force that we all have. When we die the spirit leaves the flesh. At this time the soul and the spirit are synonyms, and the words are used interchangeably in the scriptures.
This is probably in unanswerable question but if this indeed is what the soul is can anyone provide solid scientific evidence of its existence?
I hope I am not straying to far from the topic subject and am kind of new here but I thought this would be a pertinent and rather intellectual discussion.
