If your answer to that question is 'I don't have time to read!' - how about letting someone read to you? ChristianAudio.com have made loads of quality Christian books available as audiobooks - great for listening to while you're doing something you don't need your brain for, like walking to work, showering, or driving the car (OK - so you might need your brain a bit...).
Best of all if you sign up to their regular mailing list - you get a free book every month. So there's an easy way to read at least 12 good Christian books a year.
