Our true identity comes from Christ, not from our circumstances, diagnoses, or struggles. Many people confuse what they've been identifying with for their actual identity in God. Real faith isn't just hearing God's word but acting on it with obedience. James provides three diagnostic tests for authentic faith: how we use our tongue, how we treat people in need, and how much we allow the world to influence us. When God's word reveals areas needing change, we should respond like looking in a mirror and fixing what we see wrong.
