Your emotions aren't random weather patterns that just happen to you - they're spiritual indicators revealing what your heart truly believes and treasures. The biblical heart has three functions: it thinks, feels, and chooses, working together in a chain reaction where beliefs shape desires, desires create emotions, and emotions motivate choices. Anxiety reveals you're believing lies about God's care and desiring control, while anger shows you're demanding something you want right now, and discouragement exposes misplaced hope. Sin has corrupted all three dimensions of our hearts, but Christ offers transformation by renewing our minds with truth, changing our desires to treasure Him, and freeing our will to choose obedience. When strong emotions hit, ask yourself three questions: What am I believing? What am I wanting? What am I choosing? Then bring those answers to Scripture and let gospel truth transform your heart from the inside out.
