And faith isn't about perfect attendance to services, or how much money you put on the little plate. It isn't about going skyclad to the Holy Rite, or meditating each day upon the divine. Faith is about what you do. It's about aspiring to be better and nobler and kinder than you are. It's about making sacrifices for the good of others - even when there's not going to be anyone telling you what a hero you are. Faith is a power of its own, and one even more elusive and difficult to define than magic.
