It's hard to find a perfect example to learn from. Infact, apart from Jesus, there aren't any perfect examples. So what do we do with the imperfect examples that we are given - or are for others.

David too wasn't perfect, and paid a heavy price for his failure, but the difference between the two men is stark. What can we learn from them?
