The secret to Saint Paul’s profound apostolic ministry is the depths of his conversion, which is considered the greatest in Church history.  His encounter with Jesus  on the road to Damascus was only the beginning of Saul’s transformation into the great Apostle Paul.  His radical response was to withdraw for three years to Arabia. (Gal 1:17) It was there, alone in prayer, that Paul began “to grasp the length, the height and the depth” of God. (Eph 3:19)
