I do not believe one can settle how much we ought
to give. I am afraid the only safe rule is to give more
than we can spare. In other words, if our expenditure
on comforts, luxuries, amusements, etc., is up to the
standard common among those with the same income
as our own, we are probably giving away too little. If
our charities do not at all pinch or hamper us, I should
say they are too small. There ought to be things we
should like to do and cannot do because our charities
expenditure excludes them.
C.S. Lewis
