Nathan,
I have a couple of questions, things that don't seem to follow
If all men are seen as spirit, and in adam all die, the old man, earthy man, then do we have old spirit vs new spirit? Is not the old man the man of sin/ antichrist? if so then why is that man seen as a soul, not spirit if that man is adam?
I get esau, ishmael being old man, but they are men and are listed under the woman/soul dept.
The serpent has seed, wouldn't that make it a spirit?
How many licks does it take to get to the center of a tootsie pop? 
maybe I'm trying to take the analogy too far?
To answer the last first . . .absolutely not . .. you're asking questions with depth, there's no such thing as "too deep".
If all men are seen as spirit, and in adam all die, the old man, earthy man, then do we have old spirit vs new spirit? Is not the old man the man of sin/ antichrist? if so then why is that man seen as a soul, not spirit if that man is adam?Not sure if I can say this with clarity without making it sound more confusing. This is all in dimensions. In one dimension, we/I are/am the bride of Christ. We are the woman and Christ is the groom. In another dimension, we are called "sons of God". They won't appear to clash once you realize they are both true, but on different levels of understanding. In the same light, Esau and Ishmael are men, but are also representing the woman, the soulish side of man. When you take the context into account, you can easily see there is a bigger picture opening up. Ishmael is the carnal side and Isaac is the anointed side. Same with Cain and Abel. Jacob and Esau, there is always a yin to the yang of the picture being revealed when it deals with a man being seen as the soul. There will always be another man in the picture to represent the spirit man as well. Saul and David. Saul is the woman, but it's not about the "woman" because the woman will always represent the soul, the mind, the womb between our ears. So as in David and Goliath, David again is the anointed man, Goliath is the carnal man . . .it just depends on what dimension you choose to see it from.
In us there is an anointed man and a carnal man. Our carnal man is the one that needs to die, it's considered the "old man" in us. It's our spirit man, our anointed man that experiences the resurrection. The part of us that once was dead but now is alive. Read that story with Jacob and Esau in that light . . .there are so many distinct connections to this analogy that it's just very obvious that Esau is the soulish side of us and Jacob is the anointed side . . .neither is perfect, but God isn't interested in our perfection, only his perfection in us. Jacob was the anointed one, but his name was "still" Jacob . . .which means supplanter . . .not a great identity to grow up in, but God uses the most unique vessels through which his seed of promise is carried. I think it's to show that it's not about the vessel, but the contents "in" the vessel that is of any importance.
The serpent has seed, wouldn't that make it a spirit?Every tree was given the enablement to reproduce "after it's own kind". Jesus stated it like this,
Matthew 6
19Lay not up for yourselves treasures upon earth,[earthiness, carnal wares) where moth and rust doth corrupt, and where thieves break through and steal:
20But lay up for yourselves treasures in heaven,(spiritual truths)where neither moth nor rust doth corrupt, and where thieves do not break through nor steal:
21For where your treasure is, there will your heart be also.
22The light of the body is the eye: (it's all about our perception) if therefore thine eye be single, (pure) thy whole body shall be full of light.
23But if thine eye be evil, thy whole body shall be full of darkness. If therefore the light that is in thee be darkness, how great is that darkness! This whole passage is about what side of our "self" are we going to live by/in. Do I give power to my anointed man in me or to my carnal man. The carnal man will be able to have a cultivated light, that's what the "strange fire" was all about with Aaron's sons who God killed. Cultivated light is spiritual truth blended with natural rationale. We convince ourselves what we have is light, but the fruit of it will tell the truth of it's source. If it brings illumination that sets men free, then it's the light of Truth. But if it's anything else, it'll only bring division and strife. Anybody ever ask why there are so many different churches and denominations? That's why.
So, the serpent "my mind" can plant a thought in another . . .but what fruit does that thought bring forth? That's why I stated that our minds can not reproduce life. Life doesn't from from the woman, only the man. Women "can" reproduce without actually being intimate with a man, but the seed they use is still "out" of a man. So they're not really reproducing life with their own means. Our minds are the same way. They can "adopt" things without actually becoming intimate with the originator, but the truth is, it's as Jesus stated with the parable "depart from me, I never "knew" you . . .it's not about the reproduction, or manifestation of the fruit of life, it's about the intimacy, the source from where life actually comes from.
They cast out demons, they set people free . . they were showing the signs of life, yet none of them had the intimacy because by their own line of questioning, it exposes what they used to measure themselves by. It wasn't by relationship, it was by their "works". So, the satan in us can plant seeds . . .they're just not seeds of life.
