If we are good people, why do we keep on doing things that we know are wrong? Why do we also keep failing to do things that we know we should do? The two men talk again about freedom and discuss why it is so hard to be free from this kind of sinful human nature. It is like we are slaves to our passions, slaves to the things we desire. In order to be free from this slavery to sin, we need someone who is already free from sin and able to provide freedom. It is only through Jesus we can receive salvation from our sins.
