I really do not understand this pie-in-the-sky idea that I must feel positively toward the people whom I forgive. How about just some indifference toward them?
Think of forgiveness as a process. We start out with anger or sadness or some other emotion that we find unpleasant. As we grow in the moral virtue of forgiveness, the anger (or sadness) begins to diminish and we then can develop a kind of indifference toward that person. Yet, over time, and because forgiveness is a moral virtue, we might continue to grow even more deeply in our appreciation of the other as a person. This can lead to compassion, respect, generosity, and even love (the kind of love that is willing to be in service to the other for the other’s sake) toward that person. So, you might want to think of indifference as one stop on the journey to greater perfection in the growth of this moral virtue of forgiveness.
