For a moment here let's go back to the book of Genesis where God created man.
"And the Lord God formed man of the dust of the ground and breathed into his
nostrils the breath of life; and man became a living soul..." [ GEN 2:7 ]
It is very important for us to understand the "ingredients" God used to
Adam's BODY was formed of the DUST OF THE GROUND, then God added the "Breath
of Life," the SPARK OF ENERGY that brings the body ALIVE, and then "Man became
a living soul"...
It DOESN'T say that God GAVE Adam a "soul," as if a soul exists totally
separate from the body or something like that. Adam BECAME a soul when God put
the BODY and BREATH together.
So. Here's God's equation for an "alive" human being:
BODY + BREATH = LIVING SOUL
This is important. ...at death, when a man's breath (of life) goes forth,
he dies. His being, His "soul" perishes. Only a living man is a "living
soul." A dead man is dead, there's no "soul" that goes out of the body to live
elsewhere. No "soul" goes immediately to heaven, hell, or purgatory. Dead is
God said to Adam: "For dust thou art, and unto dust shalt thou return."
[ GEN 3:19 ]
...God didn't say, "You'll join me in heaven as soon as your body dies." No.
God said, "you're going back into the ground... until you're resurrected."
Also, when reading the actual Hebrew we see that God put into Adam the
breath of LIVES (plural). This is yet another translation which wasn't
correctly brought into English.
