If you have ever wondered if your faith is real, then let me excite you. What James is doing is drawing this link between genuine faith and action. Without the action, the faith is dead. In other words, how do you know that your faith is genuine? Because you act on it. Sometimes we think our faith is weak, when actually, all we’re are experiencing is lack of certainty – which is not the same as lack of faith. Because faith shows itself, not in being certain about our beliefs, but in action.
