Energetic pursuit of their work, unimpeded by distractions of social intercourse, is meant by the prohibition of saluting by the way. That does not mean churlish isolation, but any one who has ever seen two Easterns 'saluting' knows what a long-drawn-out affair it is. How far along the road one might have travelled while all that empty ceremony was being got through! The time for salutations is when the journey is over. They mean something then. The great effect of the presence of Christ's servants should be to impart the peace which they themselves possess. We should put reality into conventional courtesies. All Christians are to be peacemakers in the deepest sense, and especially in regard to men's relations with God. The whole scope of our work may be summed up as being to proclaim and bring peace with God, with ourselves, with all others, and with circumstances. The universality of our message is implied in the fact that the salutation is to be given in every house entered, and without any inquiry whether a 'son of peace' is there. The reflex blessedness of Christian effort is taught in the promise that the peace, vainly wished for those who would not receive it, is not wasted like spilt water, but comes back like a dove, to the hand of its sender. If we do no other person good, we bless ourselves by all work for others. The injunctions as to conduct in the house or city that receives the messengers carry two principles of wide application. First, they demand clear disinterestedness and superiority to vulgar appetites. Christ's servants are not to be fastidious as to their board and lodging. They are not to make demands for more refined diet than their hosts are accustomed to have, and they are not to shift their quarters, though it were from a hovel to a palace. The suspicion that a Christian worker is fond of good living and sensuous delights robs his work of power. But the injunction teaches also that there is no generosity in those who hear the message giving, and no obligation laid on those who deliver it by their receiving, enough to live and work on. The less we obviously look for, the more shall we probably receive. A high-minded man need not scruple to take the 'hire'; a high-minded giver will not suppose that he has hired the receiver to be his servant. The double substance of the work is next briefly stated. The order in which its two parts stands is remarkable, for the healing of the sick is put first, and the proclamation of the nearness of the kingdom second. Possibly the reason is that the power to heal was a new gift. Its very priority in mention may imply that it was but a means to an end, a part of the equipment for the true and proper work of preaching the coming of the kingdom and its King. At all events, let us learn that Jesus wills the continual combination of regard to the bodily wants and sicknesses, and regard to the spiritual needs of men.
