Author Skye Jethani tells the story of how Billy Graham modeled praying continually:

In 1982, the Today show in New York City scheduled an interview with Reverend Billy Graham. When he arrived at the studio, one of the program’s producers informed Graham’s assistant that a private room had been set aside for the reverend for prayer before the broadcast.

The assistant thanked the producer for the thoughtful gesture, but told him that Mr. Graham would not need the room. The producer was a bit shocked that a world-famous Christian leader would not wish to pray before being interviewed on live national television.

Graham’s assistant responded, “Mr. Graham started praying when he got up this morning, he prayed while eating breakfast, he prayed on the way over in the car, and he’ll probably be praying all the way through the interview.”
