What if I think that forgiveness is not the solution? Then what?
Forgiveness is not necessarily a solution to injustice because to right that wrong you need the moral virtue of justice. Forgiveness is a response to injustice in that you are now confronting the effects of the injustice (anger, possibly a strained relationship, disharmony in the family or organization) and so it is important to address those negative effects, if you choose to forgive. So, if you are thinking about forgiveness as solving the problem of injustice, I think you are asking the wrong question about forgiveness. Instead of “How will forgiveness solve this problem?” I would urge you to ask a different question: “How can forgiveness help me (and us) overcome the negative effects of the injustice?”
