You're making a lot of unrelated statements. I asked what your claim that we are a means to an end was supposed to mean. What is it about your belief that God is spirit have to do with our physical existence? Sounds like you are just assigning arbitrary definitions of reality with nothing to justify your definitions.
I am not attempting to speak for Ding, only making an observation. God is spirit. As such, why didn't he just create mankind in the form of spirit only? Why did God give us a physical existence to experience before we entered into a spirit existence?
Genesis hints that as God is pure love and goodness, a material existence gives us, His children, an opportunity to choose love and goodness over other qualities. It appears that some of the angels felt that an existence in the sole presence of love and goodness was somewhat lacking.
