All the delights of sense, or heart, or intellect, with which you could once have tempted him, even the delights of virtue itself, now seem to him in comparison but as the half nauseous attractions of a raddled harlot would seem to a man who hears that his true beloved whom he has loved all his life and whom he had believed to be dead is alive and even now at his door.
C. S. LewisAnyone who endeavors to be a Christian will soon find his intelligence being sharpened. You are embarking on something that is going to take the whole of you, brains and all.
