i agree that our understanding of God changes as we grow as a species. i'm with you here...
now you're putting words in my mouth

i never said God was constantly learning or even that he might be 'different'. and i certainly don't think that God changes as our understanding of him evolves. i think you're misunderstanding what i mean when i say God is dynamic.
consider this. even though our universe is constantly changing, the laws that govern it remain the same. we can reliably predict the behavior of bodies in motion, know how fast light travels, etc. as we discover more about our universe, we might revise our understanding, but those laws remain timeless. you could say the CHARACTER of the universe remains the same despite the constant changes.
i look at God in the same manner. His CHARACTER remains the same, even as more and more of it is revealed to us as we continue to grow and learn as a species. So in that sense God is static and the rules He has put forth to define morality, etc are timeless. His character is definitely unchanging.
but that doesn't preclude God from being dynamic, because the universe and everything in it is an expression of, a part of who and what God is. the divine (but finite) "breath of life" that exists in all of us and connects us to God changes and grows as we trod through the journey we call life. so as we experience, in a sense, God "experiences" too. it doesn't change WHO God is at all, but i believe He finds joy in this. much like we find joy in watching our children grow into adults, but that doesn't mean it has to change the nature of who WE are individually.
this explains (to me at least) why the Bible says God finds joy in faithful beings, and why sin makes God sad, etc. it may even give us insight into one of the grand purposes of creation in general. i have more opinions on this but i don't want to go off too far on a tangent.
i appreciate that everyone might not see it the way i do, so we'll may have to agree to disagree on this one

. i hope that by sharing you can come away with something positive, i know i have from your posts. some reps are coming your way...
