In light of the difficult economic times most of us are facing, these words from C.S. Lewis are an important reminder and lesson for God's people on how much we ought to give:
“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, amusement, 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 giving does not at all pinch or hamper us, I should say it is too small. (Tweet This) There ought to be things we should like to do and cannot because our commitment to giving excludes them.”- C.S. Lewis
Notice that Lewis doesn't address an amount or percentage, rather he address the heart of the matter, the idols of our heart - comfort & personal peace.
