Bishop T.D. Jakes, best-selling author and award-winning filmmaker, is 'beginning to improve' following a 'health incident' during Sunday service.

Bishop T.D. Jakes had a “slight health incident” while delivering a lengthy sermon on Sunday, according to The Potter’s House, the Dallas-based megachurch where he serves as pastor.

Nearing the end of an hour long Sunday service, Bishop T.D. Jakes suddenly stopped preaching, lowered his microphone, began shaking and dropped a rag before about a dozen clergy members rushed to his aid at the Potter's House in front of a standing audience of church members.
