In every great work there is the same distinction of parts and functions, all co-operating to produce the effect which seems to be entirely due to that cause which happens to come last in the series. Organisation of labour associates many hands in the different stages of the one result. There are very few things in this world which are the product of one simple cause alone. You cannot grow a grain of corn without the seed with its vital germ, the soil with its mysterious influences, the sunshine and the rain, the sower's hand and basket, the plougher's plough, and all these, except the blessed sunshine, are the results of a series of other causes which lie forgotten, but are really represented in the issue. If one of them were struck out, all the rest would be ineffectual. In a great machine all its parts are equally necessary, and a defect in a cog on a wheel would be as fatal as a flaw in the cylinder or a crack in the mighty shaft. What would become of a ship if the pintle that the rudder works on were away? The effect of a whole orchestra may depend on the coming in of the flute at the right place.
So in the work which God has given to the Church to do, there are the two forms of service, the direct and the indirect. There are the fighters and the guards of the baggage. And these two are equally necessary. That without which a great work could not have been done is great. When Luther came out from the Diet of Worms, and a knight clapped him on the shoulder, and said, 'Well done! little monk,' he had a share in the memorable deed of that day. The man who gave Luther a flagon of beer when his lips were dry with speaking there before emperor and cardinals, was included in the promise to the giver 'of a cup of cold water in the name of a disciple.'
We have brethren in Christ who have gone to the front, hazarding their lives on the high places of the field. Their hands will droop if they do not feel that a chain of sympathy stretches between them and us, for they in their solitude need all the strength which the confidence of a multitude at home feeling with them can give. They are powerfully influenced by the tone of feeling among us. When devotion languishes and faith droops here, these will generally pass through the same phases among them. When we are strong and bold, their hearts will be quickened by the pulsations of ours, and their courage heightened by thoughts of those from whom they come. Our disorders, our heresies, our struggles are all reproduced on the mission field. An epidemic here travels thither before long, and the spiritual condition of the Church at home is one of the most powerful means of determining that of the churches abroad. A blight among our vines soon shows itself in the little gardens just reclaimed from the waste.
The fighters need material helps and appliances for their work. The days in which the law for apostles and missionaries was, 'Go forth without purse or scrip,' ended before Jesus said, 'Go ye into all the world.' That condition was solemnly revoked by our Lord Himself, when He said, 'When I sent you forth without purse and scrip and shoes, lacked ye anything? But now he that hath a purse, let him take it, and likewise his scrip.' The fighters' material wants are now to be met by Christ's administration of natural means, even as before they had been met by Christ's administration of supernatural ones. His messengers cannot live, do their work, or extend the kingdom, but by the help of material appliances. Those who 'abide by the stuff' are to organise the commissariat department, and to see that those who are far ahead, among the ranks of the foe, do not want for either food or weapons, and are not left isolated, hemmed in by the enemy, and languishing because they feel that they are forgotten by those who 'live at home at ease.'
