The only helpful answer to our bitterness and anger is the gospel. Paul put it this way: “be kind to one another, tenderhearted, forgiving one another, even as God in Christ forgave you. “Admittedly, when we are bitter and angry, words like this can sound like a hyper-spiritual platitude, which pushes us to defend our bitterness by recalling the valid reasons for our pain. When we defend our angry bitterness, we appeal to a sense of justice – that to simply forgive someone who has not apologized, changed, or made amends is tantamount to condoning evil.
