And lastly, forgiveness does not change your past, - but it does unlock your future. Your forgiveness doesn't mean that the offender is forgiven, only that you chose to leave judgement with God. Where there is true repentance through specifically looking at what went wrong, relationships can be restored. Saying the prayer of confession on a Sunday morning may be good, but only if we can be more specific with God about the areas in which we fall short. If confession doesn't lead to change it means little.
Many people are willing to admit that they are sinners in a theoretical sort of way.
This can be part of the religious image. It is quite a different matter to look at what really needs to change in our lives. Sometimes so much happened and it is so difficult to sort it all out that the situation just has to be left with God. The end of the parable is that there is judgement. Oddly enough there can be no forgiveness without judgement.
