Ted Haggard could definitely be a spiritual leader again. He just has to come to terms with who he is first. Mainly, he has to come to terms with his own sexuality and not live ashamed of it. Once he's finally honest with himself, he can be honest with his new flock. He obviously has a talent for preaching and leading. He obviously wants to do good in the world. If he accepts his identity, he could resume his post as a spiritual leader and, incidentally, become one of the most powerful and influential gay rights icons on the planet.
