“We can only clear the ground a bit. If our testimony helps sweep away prejudice, enables you to think honestly, encourages you to search diligently within yourself, then, if you wish, you can join us on the Broad Highway. With this attitude you cannot fail. The consciousness of your belief is sure to come to you.” (Page 55, Big Book)
This means, if I’m failing, there’s a problem with my attitude: I’m not searching diligently enough for God within (= in the realm of the metaphysical).
