Theism is not God. It is a human definition of God that assumes that God is a being, perhaps the "Supreme Being," supernatural in power, dwelling outside the world (usually thought of as above the sky), who periodically invades the world in miraculous ways to answer human prayers or to effect the divine will.
Suppose God is not defined as "a being," but is simply experienced as a power, a presence. Then describing that experience is quite different from claiming to know who or what God is. Then the question is, "Are we delusional or is this experience real?" I think God is real and I believe we are in the process of defining our God experience in a new way that will replace the dying theistic definition of the past.
I think of the God experience as the power of life, love and being flowing through the universe and coming to consciousness in human self-awareness alone. I therefore feel that by living fully, loving wastefully and being all that I can be I can make the God experience visible. I also believe that it is my Christian vocation to build a world where all people have a better chance to live, love and to be. It is when I do these two things, I believe, that I am engaging in the essence of worship. - John Shelby Spong
I keep finding Bishop Spong helpful in thinking about what it is I believe. At this point, I really don't have discussions with others about this. I mainly reflect on what happens in church and what I read. I haven't read any books lately so these occasional emails from Bishop Spong usually give me something to think about.
