If you don't have a good case with facts to back up any accusation you make, you shouldn't take offense in the first place. Too many Christians become angered, hurt and upset on insufficient grounds. We should not make accusations recklessly. We should not act on what we think happened, but on what we know. The loving thing is to give a Christian brother the benefit of the doubt whenever possible.
Reconciliation is a matter of restoring friendship.
It is not enough just to bury a matter. Both parties must work toward a new and proper relationship for the future. Effort, time and whatever else is required to bring about sweet reconciliation should be given to make sure that the weld is stronger than it was before the break. A good weld is a picture of reconciliation. If two broken pieces of metal are welded together properly and skillfully, when stress is once again put on the metal, it will break somewhere else before it breaks at the weld.
