I need your help with Forgiveness

I've got to somehow narrow down the topic I've been given and lead a discussion table at an upcoming Womens Winter Festival (Crossroads and Cornerstone run three evenings over winter each year for women, each evening has a bible talk, yummy food and drinks, and discussion tables, about 50 turn up).

My topic is forgiveness.....eeek

What subtopic should I do?  The spectrum goes from intellectual to personal experience, the aim is to get the girls talking, but also to leave the table having learnt something.

For those who know me, is there something that I personally can bring to the table? 

Help!
