Quote by C.S. Lewis

“Now pain, like the other evils, may of course recur because the cause of the first pain (disease, or an enemy) is still operative: but pain has no tendency, in its own right, to proliferate. When it is over, it is over, and the natural sequel is joy. This distinction may be put the other way round. After an error you need not only to remove the causes (the fatigue or bad writing) 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. Pain requires no such undoing. You may need to heal the disease which caused it, but the pain, once over, is sterile—whereas every uncorrected error and unrepented sin is, in its own right, a fountain of fresh error and fresh sin flowing on to the end of time.”
