It's time to study Gen 2:7 over and over (avoid KJV fraud) until you begin to uderstand it, hosepipe. :)
Actually the Book of Genesis is what caused me to think we had a spirit or really "were" spirits riding the vehicle(body) God created for us and the metaphor of "breathing into us" was code for adding the spirit to the body suit... Its all about the metaphor..
The Bible really is all about code/metaphor.. Jesus spoke in metaphor(usually) as did God(Jesus, Father, Holy Spirit) in the old testament.. Jesus existed long before Mary was even born.. You miss the "metaphor" you miss the "message".. You take the literal you gloss over the hidden meaning which is not hidden.. Spirits speak metaphor..
You look into the mirror what you see is not you, thats your transportation.. mere flesh.. casket fodder.. The spirit, your spirit, who you are, is looking back at you thru your eyes(metaphorically)..
Thats NOT gnostic.. The gnostics were/Are too caught up in fatalism and Flesh.. what they called spirit is soul as do every other religion including christian ones..
The truth is its not what you believe its whom you Are that counts.. for "You MUST be born again"- Jesus.. Therefore you can be a heretic and still be born again.. yes even a gnostic.. Family is family, funny beliefs are just mental flesh games.. the human brain is flesh you see.. No casket ever buried has a spirit in it.. because thats what baptism is, a burial.. Where the "old man" is symbolically(metaphorically) buried..
