I feel that all religions in the forms they've taken over the last 1500-3000 years could be more or less extinct within 200 years, if they fail to adapt to the intelligence and consciousness of our younger and forthcoming generations.
I am currently reading a book called "God in us: A case for Christian Humanism" by a Church of England Bishop, who descibes himself as an atheist. He goes on to describe that he's only really atheistic to the "king god" notion that he used to subscribe to (God in the clouds / heaven, judging and with omnipotent abilities to act, while often not).
The author (Anthony Freeman) now believes that God is not external. S/he doesn't exist externally at all - just within our consciounces and consciousness.
Love, compassion, joy, etc, are God.
Anyway back to the point - Freeman (who is still a bishop in the CofE, although he was sacked by his parish), believes that Christianity must "adapt or die".
The "king god", personal notion of God just does not stand up to proper scrutinty and investigation when approached rationally. If this god existed, able to stop the suffering of babies and children, and chose not to, what sort of monster would he be?
If you watch this short video from
Jay Lakhani you will see a similar perspective within Hinduism. He describes the fact that reason can not be ignored when considering God, and that young people and emerging generations especially will reject God notions that are inconsistant with reason;
I am a Panentheist; for me God is everything, in everything and of everything. Every experience that is held in the universe (joyful, painful, blissful, tragic) are being experienced by god. God for me is never external and always internal; hence I'm in agreement with the above views.
Religions that are primarily concerned with external authority, legalism and rules, promises and threats - I really believe have a short future left, as mankind's consciousness and intelligence continues to evolve.
