We 'have all we want' is a terrible saying when 'all' does not include God. We find God an interruption. As St. Augustine says somewhere, 'God wants to give us something, but cannot, because our hands are full - there's nowhere for Him to put it.'
C. S. LewisThe full acting out of the self's surrender to God therefore demands pain: this action, to be perfect, must be done from the pure will to obey, in the absence, or in the teeth, of inclination
C. S. LewisThere is a difficulty about disagreeing with God. He is the source from which all your reasoning power comes: you could not be right and he wrong any more than a stream can rise higher than its own source. When you are arguing against Him you are arguing against the very power that makes you able to argue at all: it is like cutting off the branch you are sitting on.
C. S. Lewis
