"Is it really possible to slay the dragon of pornography and fantasy once it has gained control of your life?" asks Powlison. The answer is yes, you will see from this interview with a man called Bob, who experienced Christ's deliverance in this part of his life. "Private sexual fantasy can preoccupy vast areas of a person's mental life," notes David Powlison. "As explicit sexual images proliferate in films and magazines, on television, and over the Internet, the temptations increase and the bondage seems unbreakable. Even Christians can find that their lives have become a push- pull struggle between indulging in fantasy and resisting it."
