This is a tough concept. I have spent some time trying to understand why forgiveness *really* is for us. We know that it's for healing. We hear that all the time.
But I read somewhere that the real reason we forgive is because we, none of us, are so perfect that we would not need forgiveness ourselves. To forgive is to admit that deep down we would want to be forgiven if we did the unforgivable. And yes, it is to admit that we too could do the unforgiveable.
It's certainly not easy to do.
