Let me ask you this: Have you ever been, or are you right now, plagued with difficulty in forgiving some people for some things? If so, I have some good news for you. The whole idea that it is either easy or difficult to forgive someone has NOTHING to do with what it means to forgive. Forgiveness, as you are considering it, is not difficult, but impossible. For it is, in every sense, miraculous.
there is no advice in this world – even if it comes from a Bible verse or a preacher’s sermon – that can produce God’s work within you. Oh, it might make you appear more spiritually productive, but the working of God doesn’t come from the practical side of the grave … but from the living side that has risen past it. When I tell you that Christ is your life, I’m telling you about the one and only present-tense reality that causes you to live as one who is truly alive in this world. source
