The founder of Dallas-based megachurch The Potter’s House, Bishop T.D. Jakes, suffered what the church called a “slight health incident” while delivering his sermon at the church.

Jakes, 67, was speaking to churchgoers Sunday when he sat down and began trembling as several people gathered around him, with one person asking for prayers.

“Bishop T.D. Jakes experienced a slight health incident and received immediate medical attention following his powerful hour long message,” the church said in a statement.

Jakes’ daughter, Sarah Jakes Roberts and her husband Touré Roberts, said in a social media video late Sunday that Jakes was improving.

“Bishop is doing well, he’s recovering well, he’s under medical care, he’s strong, Touré Roberts said.

The couple did not say where Jakes was taken and a message left with the church Monday morning was not immediately returned.

Jakes founded the non-denominational The Potter’s House, which now has more than 30,000 members, in 1996 with campuses in Fort Worth and Frisco, Texas, and Denver, according to his website.
