I sometimes suspect that what we feel to be our best prayers are really our worst; that what we are enjoying is the satisfaction of apparent success, as in executing a dance or reciting a poem. Do our prayers sometimes go wrong because we insist on trying to talk to God when He wants to talk with us? … St. Augustine says, ‘God gives where He finds empty hands.’ A man whose hands are full of parcels can’t receive a gift. Perhaps these parcels are not always sins or earthly cares, but sometimes our own fussy attempts to worship Him in our way.

- C. S. Lewis
