Believing in God is an intellectual position. It need have no more effect in your life than believing in Freud's method of interpreting dreams or the theory that Sir Francis Brown wrote Romeo and Juliet.
Believing God is something else again. It is less a position than a journey, less a realization than a relationship. It doesn't leave you cold like believing the world is round. It stirs your blood like believing the world is a miracle. It affects who you are and what you do with your life like believing your house is on fire or somebody loves you.
