Last week, ABC Nightline crews took over Mars Hill Church in Ballard to videotape an unusual debate: Does Satan exist? Among the debaters, Mars Hill Pastor Mark Driscoll and philosopher Deepak Chopra.

“There were approximately 800 people in attendance,” Cliff Ellis from Mars Hill told My Ballard earlier this week. “It will be interesting to see how two hours of footage is edited down to three ten-minute segments.” The show airs tonight on ABC at 11:30 p.m., but it’s already available online right here.
