The goal of pursuit of justice must not simply be that justice happens but that reconciliation also happens.
The difference between justice and forgiveness: To be just is to condemn the fault and, because of the fault, to condemn the doer as well. To forgive is to condemn the fault but to spare the doer. That's what the forgiving God does.
If I say, 'I forgive you,' I have implicitly said you have done something wrong to me. But what forgiveness is at its heart is both saying that justice has been violated and not letting that violation count against the offender.
Christians believe that there will be a Judgment Day at the end. And it is my belief that on that day justice will be done and there will be a reconciliation between those who have profoundly injured one another takes place.
