Elizabeth Gilbert said this quote
“ Devotion is diligence without assurance. Faith is a way of saying, 'Yes, I pre-accept the terms of the universe and I am voicing in advance what I am presently incapable of understanding.' There is a reason that we refer to leaps-of-faith, because the decision to consent to any notion of divinity is a mighty jump from the rational over to the unknowable, and I don't care how diligently scholars of every religion will try to sit you down with their stacks of books and prove that their faith is rational; it isn't. If they were rational, it wouldn't be - by definition - faith. Faith is belief in what you cannot see or prove or touch. Faith is walking face first and full speed into the dark. ”
