Forgiveness and reconciliation are two different things.

The phrase "forgive and forget" is foolish. Always remember, never forget who has harmed you and may harm you again.

However, Jesus taught us the lesson of forgiveness. We must forgive ourselves, and should probably forgive others wherever possible, at least inwardly. Whether that forgiveness takes on an outward gesture to the actual person is less important than the internal forgiveness we grant the person through letting go. However the outward forgiveness gesture can be a very powerful force of good, too.

Lack of forgiveness of others creates a constant state of strain in your relationships. Lack of forgiveness inwardly to others, and especially to one's self, is a recipe for failure.
