If a thing is free to be good it is also free to be bad. And free will is what has made evil possible. Why, then, did God give them free will? Because free will, though it makes evil possible, is also the only thing that makes possible any love or goodness or joy worth having.
C. S. LewisThe man can neither man, nor retain, one moment of time; it all comes to him by pure gift; he might as well regard the sun and moon as his chattels.
