There are two issues here. The first is the offended person’s forgiveness process and the other is the feelings and needs of the one who wants to be forgiven. The first issue is basically care of the self, which we have to do. As long as the one forgiving is slowing down or stopping for a good reason, then it is fine to back off, rest, and try to gain strength before pressing on to forgive. Forgiveness is hard work. A reason that is not good is this: slowing down the process to frustrate the other person. This, of course, would be revenge, which is not even close to the process of forgiveness. So, slowing down or stopping for now can simply show the forgiver how hard it is to sustain this virtue.
The second issue concerns the needs of the one who wants forgiveness. Again, we are presuming a good reason for the forgiver’s slowing down. Under this circumstance, it is part of the offending person’s bearing the pain in waiting. There are no guarantees once a person asks for forgiveness and so part of that process is to have patience and to give the forgiver a chance to grow into a forgiving response. The waiting can be painful, but if endured for the sake of the forgiver, it can lead to forgiving, receiving the forgiveness, and reconciling.
