What’s the difference between soul and spirit? It’s physical, that is, describable with Physics.
No one can pay the price to redeem a soul and live forever, no matter how rich they may be. That's a valid statement, but it may be missing the point. This gets us into a discussion of gravity which is the very essence of time.
We can combine the doctrine that we've existed from the foundation of the world (first cause), gravitation, the broad narrative of scripture, and redemption into a unified theory of everything and deduce the nature of the soul.
Time is a field emitted from the singularity at the center of the Earth which causes a linear progression of moments to pass at a rate which is proportional to the square of its distance from the source.
"Soul destroying" is commonly used to mean "causing a person to feel very unhappy or depressed." For example: the soul-destroying confinement of city life. This means that the soul is continuing in its unhappy state.
We (that's me and the Holy spirit) have made an extensive study of how the zones of the interior of the Earth, or levels of hell, may be deduced from Biblical Hebrew and Greek.
In the Bible the heart does a lot more thinking than our minds do. This runs counter to conventional medical wisdom about the brain and heart, but are we worried about running counter to convention?
If science can't detect it then it doesn't exist. That's rhetoric which crops up on social media quite frequently. The soul is undetectable by popular science (SciPop) which is why scientists dismiss the possibility that it exists.
The connection between the soul and the blood, as the life of the individual, is strong, but there's more to it than that. The soul isn't simply the result of the spirit dissolving in the blood.
The Hebrews had an innate sense that the soul was wet, or was in a liquid state, as is evident from the concept that it could be poured out.
When God breathed life into Adam he became a living soul, so there's a connection between the life and the blood, which is why the Children of Israel and the early Church had prohibitions on eating blood or meat with blood in it.
