Seeker, I am not understanding how God comes into play in your explanation. It sounds to me as though your idea sounds like a "we are God" theory. Can you explain the interactions between our Spirit and God according to your understanding?
I have a different understanding of the matter. I believe that our spirits die when we come to earth and we are sustained by the light of Christ until we are born again spiritually. After that time, I can believe that we are guided by our own spirits and that our spirit acts as a Holy Ghost within us. There must be a separation from our spirit if we are to receive it again.
