The Savior chose a very dramatic moment in which to emphasize the value of missionary work. He gave to his apostles the choice of their hearts. Peter said that he preferred to depart speedily from this life and be with the Savior in his kingdom. John the Beloved chose to stay behind and bring souls unto Christ. Imagine the importance of that beautiful moment, Peter choosing to be with the Savior in his kingdom above; and yet the Savior turned and said to Peter, “John my Beloved has chosen the greater thing.”
