Actually if you just believe in God you can’t live a spiritual life.
We can’t enter spirituality based on belief because beliefs are not based on what spirituality actually is; they’re fantasies of how we’d like it to be without doing anything to find out what it is. How do you know when you’re in a place? Only by the sensation you have within your own experience. If you go by anything else, then you don’t actually live there, – you just live as though you live there, as though there’s an all-inclusive, loving force. Spirituality isn’t vague or abstract.
