Have you ever picked up a can of soda and tasted it, only to discover it was...flat? Our spirituality becomes like that drink when we lack the kind of genuine faith in the Gospel that characterizes every part of our lives. The "fizz" in our spiritual lives comes from having trust in God and joy in His presence regardless of our circumstances. And when people who don't know God see that fizz bubbling over into everything that we do, they find themselves attracted to the same kind of contagious faith that we have.
