Minister Sentenced for Sexually Abusing Women

Along with Catholic molester priests there are a whole host of evangelical ministers and pastors who abuse people sexually. Just recently one was sentenced to prison for this. See here. What do you Christians makes of this? Ministers commit adultery, molest children, sexually abuse women, pilfer money from the church, and so on. Pastors are supposed to be the best examples of Christianity, but they don't seem any better than any other Christians. Why is this? Where is the power of the Holy Spirit in their lives? Why is it that Christianity is the only religion that claims a creator God (via the Holy Spirit) takes up "residence" in the life of the believer but it doesn't produce people who act any better than anyone else, especially its pastors?
