Not to be discounting ,but is that to say that a native american's personal relationship with the Great Spirit is any less valid than your relationship with God?
Or if I should be so bold, how about a young Muslim who is willing to give his life in the service of his personal relationship with Allah. How could you ever question his faith as he is willing to put his life on the line owing ,to his pure conviction.
Obviously I don't in any way condone killing or violence of any sort in the name of religion, I am just trying to make the point that there are other individuals that believe fully based on their own personal experience that their creator is the only true creator.
Where does that leave us? It leaves us exactly where we have been for milleniums-killing each other over our differing beliefs and tribal affiliations.
