Why tell?

I checked out a book titled A Lifetime of Secrets. It was compiled by Frank Warren. He asked people to send him postcards telling him anything they wanted to get off their chest. As I have been reading through it, I have seen the need for man to be forgiven and forgive. So many people are seeking resolution but are too weak to actually follow through. This is not to say that I am better, but that I am also weak and am even more thankful that I have been forgiven.
