C. S. LewisAnyone who is honestly trying to be a Christian will soon find his intelligence being sharpened: one of the reasons why it needs no special education to be a Christian is that Christianity is an education itself. That is why an uneducated believer like Bunyan was able to write a book that has astonished the whole world.
