God sees you as one soul. We often forget to remember that God's perspective is far more vast than ours, and isn't bound by OUR concept of the time/space continuum. I believe that the soul is created/implanted during the fertilization process; when a human is "one" with Him.

Only one aspect of you needs to accept God. Truly, if someone is segmented and that breaks apart the various capabilities of the mind there is no way that each aspect could fathom the concept of need or even of God, since each segment has a different purpose and capability, imo.
