Apparently, the interview was placed on Houston’s website on July 28.
— Hillsong Church (@hillsong) July 28, 2015
It has been posted at Vimeo (see the end of the post)*
A transcript of the interview is here (not flawless but a good effort).
At the same time as the video has been posted, Driscoll announced that he has moved to Phoenix.
Houston has done Driscoll a huge favor with this interview. It will be interesting to see if Driscoll plants a church in a city where Hillsong has a significant presence. In fact, Hillsong purchased a building Mars Hill once considered for the Phoenix expansion. Mars Hill launched Mars Hill Phoenix in 2014 which later became Phoenix Bible Church later that year.
