Forgiveness is achingly difficult, and long after you've forgiven, the wound lives on in memory.  Forgiveness is an unnatural act.  I never find forgiveness easy.  Nagging injustices remain, and the wounds still cause pain.  I have to approach God again and again, yielding to him the residue of what I thought I have committed to him long ago...God forgives my debts as I forgive my debtor...only by living in the stream of God's grace will I find the strength to respond with grace towards others. (Philip Yancey, What's so Amazing About Grace)
