Paul was a leader by appointment and by universal recognition and acceptance. He had many mighty forces in this ministry. His conversion, so conspicuous and radical was a great force, a perfect magazine of aggressive and defensive warfare. His call to the apostleship was clear, luminous and convincing. But these forces were not the divinest energies which brought forth the largest results to his ministry. Paul's course was more distinctly shaped and his career rendered more powerfully successful by prayer than by any other force.
