Wrong God is perceptible in how he works in your life for your good. It's just that most people don't see or understand it.'God' would only be perceptible by some extraordinary experience. All other information about 'God' is necessarily second hand.So I can find your god without ever opening a bible?No. Not study a book. Seek him.It led to an invisible being who wants us to study a book?Creation is real and exists and can be examined just like a painting.Only because paintings are real and so are painters and we can compare their works... You're assuming that your invisible friend is real. Nobody has proven that. Yet.
Unlike you I did not start from an assumption. I examined the data and followed where it led.
If 'God' is not knowable without books, 'God' is unknowable.
