In "What Rules Your Heart?", Pastor Byron Chesney examines Colossians 3:12–17 and shows how a believer's union with Christ should change the way he treats others. Christians are called to put off the attitudes of the old life and daily put on mercy, kindness, humility, meekness, patience, forgiveness, and charity. Through biblical teaching and a personal story about responding to a hateful customer, this message emphasizes that difficult people and circumstances reveal what is controlling the heart. Anger, pride, fear, and bitterness produce conflict, but when the peace of God rules within, the character of Christ is displayed through our words and actions. The message challenges every believer to let the Word of Christ dwell richly within and to ask honestly, "What rules my heart?"
