Guard your heart
The conference theme is going to be on habits of the heart. But the theme verse is, "Above all else, guard your heart." Why should you guard your heart? Guarding your heart is absolutely crucial, because you never know what's going to come along. If you're not ready, your heart might be stolen, your heart might be broken; or tragically, Your heart may become hardened. And where your heart goes, so goes the rest of your life.
