form of thoughts, emotions, and behaviors finds its origin inside of us. Too often, we focus our attention on changing the external rather than addressing the internal. But Jesus was very clear that what defiles us proceeds from inside our hearts—our beliefs and our motives. The fruit of our lives comes from the roots of our faith. Just as a thermometer detects a fever, what we see or experience tells us about the gospel health of our hearts. So we need to learn to trace the fruit back to the root.
