Religious book v.s. techy book...

Two nights in a row, I had the option to read either 'Head First Java' or 'The Reason for God - Belief in an Age of Skepticism' and both nights I chose to read the latter. Not sure why I do that, perhaps I am feeling a bit guilty that this book has been sitting on my bedside for longer than a year now and I've never read over 100 pages of it (total < 300 pages) Or maybe I am just a bit spiritual?
