We have meditated upon our work as messengers, and then on our work as physicians and surgeons; but the duties given us are so various that it ought to make us feel how extraordinarily full of interest our work is. Every faculty of the mind and spirit is wanted for this wonderful work. We are called sometimes stewards representing the Master to the people of the world, looking after the menservants and the maidservants, foraging for the food of the household and giving it out. Then another time we are watchmen on the walls of Jerusalem, walking up and down watching over the city and blowing the trumpet when the danger comes, continually holding up our hands in prayer. We do our work as messengers running with a message, as physicians and surgeons going up and down the ward, and then suddenly we hear a voice ring, as it were, from heaven: "Follow Me, and I will make you fishers of men." Here we have quite a different picture--the wind-swept deck of the fishing-smack in the teeth of the tempest. "Cast the net on the right side of the ship, and ye shall find." We are fishers fishing for men. What a different picture from the others! And I think we ask, rather sadly, some of us, who have been working night and day, whether we are successful fishers of men. We say: "Master, we have toiled all the night and taken nothing." I have this huge parish of ten thousand people to look after, and what is the result of my work among them? Have I been a successful fisher of men? And that makes us, of course, ask ourselves in a day like this: "What is the secret of successful fishing? If I have toiled all the night and taken nothing, and all the day and taken very little, what ought I to do? My time is getting on; the evening will come, my fishing will be over. Can I not discover in the presence of my LORD to-day what He would have me do different from what I have been doing, that I may bring to His feet a greater harvest of souls than I have ever brought yet?"
