A lifetime of study and thought about world religious beliefs. I don’t believe we can draw the kind of comparisons you suggest between this material plane and the spiritual one, and the Unity of God doesn’t leave room, in my mind, for a Devil and Demons. But God did give man free will and sometimes our own choices create hellish circumstances for us and pervert our mentalities.
Just like you, I’m comfortable with my conclusions. I think expression of individual beliefs can make for interesting conversation; but too often they break down into argument over sectarian doctrine. I have no desire to change another person’s mind. Spiritual issues are highly individual and subjective, and no two people ever really see them in the same way.
And I don’t think they need to do.
Oh, do they ever. My godly pay grade isn't high enough for me to tell anybody what they must believe. I kind of like your viewpoint, and appreciate your friendly conversation.
