Billy Paul's Hard Job: Discernment in William Branham's Healing Revivals

William Branham claimed that his son, Billy Paul Branham had the "hardest job" in the revivals: giving people a card that collected their name, address, and disease, called "prayer cards." Branham claimed that passing these information-collecting cards was so difficult that it caused "four different men to have breakdowns."

Was it really that hard? What position did Billy Paul play in these revivals?
