Don’t be afraid of doubt. OK, it may feel like a threat, but you can also treat it as a tool to help you dig down to the solid ground of your real faith. I'm avoiding the adjective “true”, because it’s so often used in a negative way. “True Faith” (note the capitals) implies a set of beliefs that we have and they don’t. My real faith consists of the things I believe deep down, and those beliefs have been tested again and again – by doubt.
