Memory: My Failures (1 Timothy 1:12-16)

As the second lesson in a series on Memory, we look at the biblical perspective on memories of my own failures. Among others, we examine Paul - a man who says he is forgetting what lies behind and yet still talks about his past a great deal. Is it possible to forget my mistakes of the past? And if it isn't, what does Paul mean? If memories are not forgotten, how can they be redeemed?
