If you really believe something, you will act in accordance with that belief — always. If you believe in gravity, you will never attempt to defy it. If you claim to hold a belief but act incongruently, then you don’t actually believe it. You’re only kidding yourself. Casual faith isn’t.
Actions, not words, reveal beliefs. If you want to understand what you truly believe, observe your actions. This may take some courage to do, but if you follow the trail of your actions, it will lead you to a more congruent belief system. And once there you can begin consciously moving towards new beliefs that empower you, while your actions and beliefs remain congruent along the way.
