First - Goodness is bad when goodness evades greatness. Sometimes we are tempted to settle for doing good when we could be doing something great. Good enough is rarely good enough.
Second - Goodness is bad when goodness avoids service. The world’s problems and needs are messy and unpleasant things. Sometimes our desire for goodness keeps us from diving in and fixing these nasty realities.
Third - Goodness is bad when goodness shuns people. When good people cluster together in their shared goodness, those who aren’t so good remain blind to their own needs but see clearly the hypocrisy of those who claim to be good.
Take Away: Being good can be bad, if being good is only for goodness sake.
