The heart is powerful. It’s powerful enough to determine the course of our lives: what we feel, what we say, and what we do. That’s why our hearts are so important to our relationship with God. Being close to him and living out his purpose for us means not only letting him change the way we act, but also letting him change our hearts. Check out this Scripture Playlist to learn more about how God can change us from the inside out.
Guard your heart above all else, for it determines the course of your life.
