After an error you need not only to remove the causes but also to correct the error itself: after a sin you must not only, if possible, remove the temptation, you must also go back and repent the sin itself. In each case an 'undoing' is required.
C. S. LewisI wish they would remember that the charge to Peter was "Feed my sheep", not "Try experiments on my rats", or even "Teach my performing dogs new tricks".
