'The trumpet at Thy lips, the clarion Full of Thy cry, sonorous with Thy breath.' Let us see to it that by fellowship with Christ we keep the passage clear, and become recipients of the inspiration which shall thrill our else-silent spirits into the blast of loud alarum and the ringing proclamation of the true King. The heavenward look will guard us from the temptations which surround all our service, and the distractions which lay waste our lives. It is habitual communion with Christ that alone will give the persistency that makes systematic, continuous efforts for Him possible, and yet will keep systematic work from degenerating, as it ever tends to do, into mechanical work. There is no greater virtue in irregular desultory service than in systematised labour. The one is not freer from besetting temptations than the other, only the temptations are of different sorts. Machinery saves manual toil, and multiplies force. But we may have too heavy machinery for what engineers call the boiler power,--too many wheels and shafts for the steam we have to drive them with. What we want is not less organisation, or other sorts of it, but more force. Any organisation will do if we have God's Spirit breathing through it. None will be better than so much old iron if we have not. We are ever apt to trust to our work, to do it without a distinct recurrence at each moment to the principles on which it rests, and the motives by which it should be actuated,--to become so absorbed in details that we forget the purpose which alone gives them meaning, to over-estimate the external aspects of it, to lose sight of the solemn truths which make it so grand, and to think of it as commonplace because it is common, as ordinary because it is familiar. And from these most real dangers, which beset us all, there is no refuge but the frequent, the habitual, gaze into the open heavens, which will show us again the realities of things, and bring to our spirits, dwarfed even by habits of goodness, the renewal of former motives by the vision of Jesus Christ. Such constant communion will further surround us with an atmosphere through which none of the many influences which threaten our Christian life and our Christian work can penetrate. As the diver in his bell sits dry at the bottom of the sea, and draws a pure air from the free heavens far above him, and is parted from that murderous waste of green death that clings so closely round the translucent crystal walls which keep him safe; so we, enclosed in God, shall repel from ourselves all that would overflow to destroy us and our work, and may by His grace lay deeper than the waters some courses in the great building that shall one day rise, stately and many-mansioned, from out of the conquered waves. For ourselves, and for all that we do for Him, living communion with God is the means of power and peace, of security and success.
