Weakness is not the kind of weakness which we show by sinning and forgetting God, but the kind of weakness which means being completely supple, completely transparent, completely abandoned in the hands of God… You could think of that [weakness] also in terms of a sail. A sail can catch the wind and be used to maneuver a boat only because it is so frail. If instead of a sail you put a solid board, it would not work; it is the weakness of the sail that makes it sensitive to the wind.
