Roberts Liardon tells us that all denominations crowd the hall—Catholics, Episcopalians, Presbyterians, Methodists, Baptists, United Presbyterians, Primitive Methodists, Methodist Protestant, Pentecostal Nazarene, with many others, may be seen among those at the altar seeking Divine aid. Several hundred seekers after God crowd the platform daily.…Doctors, lawyers, financiers, merchants, professional men of all types and caliber. Christian Scientists—including practitioners—nurses, and head nurses from the hospitals and sanitariums, all seeking soul salvation or bodily healing. It is a sight that astounds the onlookers to see those multitudes seeking their way to God….Beyond belief are the results.

John Sproul had fought in WWI as a young soldier. While he was on a special assignment to secure supplies in France, he and a friend were hit with mustard gas. The friend died within a day or two, but John survived—just barely. He had to have fourteen operations in the French hospital where he was admitted. Six operations were performed on his throat and eight on his lungs. Following the operations, he completely lost the ability to speak, and so many of his neck muscles were cut away that he had a hard time holding his head up.

Sproul returned to the States in constant pain, with hemorrhaging in his lungs and frequent bouts of stomach sickness or sudden unconsciousness. He traveled throughout the country trying to get medi­cal help, but his case was declared hopeless. When he returned to his hometown of Pittsburgh, the mayor, Edward Babcock, took up his cause. The country was disturbed by the lack of medical aid for wounded veter­ans, so Mayor Babcock and the local congressmen sent Sproul to Wash­ington, D.C., for special medical treatment.
