How do Christ-centered messages effect change in the way we live our lives each day? We obey God because we love him, not to avoid punishment or to get things from him. Threatening people with punishment or enticing them with "stuff" cause people to respond to God out of selfish motivations. Encouraging people to obey God because of our love for Him and gratefulness for His love for us produces holiness. If grace is not put into the equation of human works and divine acceptance, then legalism or moralism results. The rules don't change but the reason we obey changes. We motivate by grace, not by guilt.
