A brother in Christ’s carelessness keeps replaying in your mind. A sister’s comment turns a sunny day dark and leaves you distracted and distressed. Try to throw the memory away from you, and it comes back like a boomerang.The apostle Paul tells us what to do when such offenses come: “Be kind to one another, tenderhearted, forgiving one another (Ephesians 4:32)." Without regular forgiveness, the love of a local church dies. Eventually, the church dies too. But how do we move from offense to forgiveness, especially when the moment keeps coming to mind?
