Audible today is expected to add sermons by Bishop T.D. Jakes -- a pastor of one of the largest "megachurches" in the U.S. -- to its online library. Audible will offer a digital subscription service for sermons from the megachurch, charging subscribers $14.95 per month to join "The Potter's House Audible Listener Plan" for spiritual teachings as audio downloads, according to The Wall Street Journal. Reverend Jakes will reportedly hand out iPods to promote the service at the annual "MegaFest" which expects to accumulate over 200,000 people in Atlanta's Georgia Dome next week.
