When a child is born (according to the flesh/alive flesh), it does something, motivated by the flesh, because we/not God are born with alive flesh. There are different and accurate definitions of the word flesh, but I am partly referring to the natural ability for your body to be motivated to do something based on the love for me/I. That is really only a part of the definition of flesh/alive flesh though. When God was born in an uncorruptible earthen vessel (dead flesh), the flesh never motivated God, and could never poison any part of God. God ate with us for our sakes, He didn't have to eat to live. God was baptized in our midst for our sakes, not because He needed to be baptized for Him to live. Every movement and word He spoke was specifically that way for a reason. He never contradicted Himself in any way, but from perspectives formed without God there is contradictions.
Perhaps I should be using a different set of words to call this explanation, but dead flesh is the opposite of alive flesh, I guess it just depends on if somebody really thinks that these bodies are all we got? The flesh exists for all eternity, it is the earthen vessel that is motivated by a spirit/soul combo. If this earthen vessel motivated by a spirit/soul combo is only motivated by the Holy Spirit without measure, then we are a holy spirit by measure. We (spirits) have earthen vessels, individual members, all part of one single body and family. We call the stuff the bodies are made of now: earth/dust/ground. We have motivated free-will only (the soul), we do not exist without a motivator. God the Father is a motivator, God is also motivated (but that's a whole different threads worth lol), and with God there is no motivation from the flesh, and I call this dead flesh, because it's the opposite of living/alive/able to be poisoned/able to motivate/etc. (this is why God cannot be tempted with evil, because the flesh has to be alive in order for the flesh to be affected by the temptor). This is also why evil does not come from God, but yet it does when you consider that God allows alive flesh to exist because of motivated free-will. The flesh was always dead, until somebody put it on and was brought under the power of it. You cannot be brought under the power of flesh if it is dead, because dead flesh has no power. You can only be brought under the power of alive flesh. I believe all will have dead flesh at some point, and at that point you can exist in the Kingdom of Heaven/God, because at that point you are only under the power of God. If you are dead to the flesh (according to the perspective of the flesh, you=dead) then the flesh is dead to you (according to the perspective of The Spirit of God, you=alive). If I am dead, the perspective is the flesh. If I'm alive, then I'm talking from the spirit perspective. I hope this is easier to understand. We'll see. I figure I can give all the scripture I want, but until you understand the perspectives, you probably won't get it.
