It seems reasonable to believe that if a person really wants to change, they will change.

In 1986, Steve Gallagher had a powerful experience of repentance and began fighting with all of his strength to find freedom from sexual sin. But it took him a long time, and there were repeated failures. At first, his wife Kathy thought this meant that he wasn’t actually serious about finding victory. But soon she began to realize that Steve was fighting a very powerful addiction, and that human willpower was not sufficient to break the spiritual chains of pornography addiction.
