1. To define it. A lot of people think of faith the way I once heard it defined in a movie, as believing when common sense tells us not to. Sometimes faith does defy common sense; expecting miracles, for instance. Miracles are earthly impossibilities, so they defy physical laws and yes, reason based on those. Faith isn’t senseless, though. Even to expect miracles is its own kind of reason if expectation is based on like experience, as I’ll get into in point two, or on knowledge of a power that transcends physical law. Faith, the good kind at least, isn’t blind, either. At the very least, it has a perfectly dependable guide dog. The kind of faith that says, “I will be healed of cancer because I believe in God” sometimes strikes me as blind not because God can’t heal cancer, but because there’s no definitive promise of indiscriminate healing on which to base such assurance. Saints die, too. Faith, the kind you can offer that people might want, can’t just be sentimental and optimistic. It has to be rational. To this end, talking about your faith in terms of its reasonable basis is helpful.
2. To testify to its effectiveness. You might try Oxy Clean if its commercials sound promising. If your mother tells you it took out wine and chocolate from her white cashmere just last week, though, you’re going to go out and buy it. Personal experience as a basis for believing something (Great Aunt Rose’s agita was relieved after eating watermelon, so watermelon must cure agita) is a bad system of reasoning. But people crave it as corroborating evidence to what already makes sense on paper. Sometimes they just want to know, seriously, did this work for you? If you’d tell them about Oxy Clean, why not the way God brought you through unemployment or loss?
3. To decompartmentalize it. (Microsoft doesn’t recognize this word, but military families will.) There’s a false dichotomy, even among Christians, of secular and sacred. If there’s a Biblical God, there’s no realm of life into which he doesn’t enter. That recurring tree model of truthàbeliefàemotionàaction? Let’s bring it in again. If your roots, your underlying truths and assumptions, are Biblical, there’s no branch of thought or actions that is separate. Unless you have multiple personalities, you don’t get two root systems, churchy and worldly, among which to compartmentalize the stuff of life. Talking about faith in the varied contexts of your life and happenings helps to bridge this artificial gap.
4. To sort it out for yourself! If this all sounds a little intense, and you don’t picture all your thoughts and opinions hung neatly from branches, talking about your faith can help you start to fit it into a bigger picture.
Not talking about faith doesn’t make sense for a person who really has it. Talking about it may just help you spot its workings and reinforce its effectiveness for you. Faith is not a salve or a placebo. Not in my experience.
