A trumpet note is, first of all, clear. There should be no hesitation in our witness; nothing uncertain in the sound that we give. There are plenty of so-called Christian people whose lives, if they bear any witness for the Master at all, are like the notes that some bungling learner will bring out of a musical instrument: hesitating, uncertain, so that you do not know exactly what note he wants to produce. How many of us, calling ourselves Christian people, testify on both sides; sometimes bearing witness for Christ; and alas! alas! oftener bearing witness against Him. Will the trumpet, the instrument of clear, ringing, unmistakable sounds, be the emblem of your Christian testimony? Would not some poor scrannel-pipe, ill-blown, be nearer the mark? The note should be clear.
The note should be penetrating. There is no instrument, I suppose, that carries further than the ringing clarion that is often heard on the field of battle, above all the strife; and this little church at Thessalonica, a mere handful of people, just converted, in the very centre of a strong, compact, organised, self-confident, supercilious heathenism, insisted upon being heard, and got itself made audible, simply by the purity and the consistency of the lives of its members. So that Paul, a few weeks, or at most a few months, after the formation of the church, could say, From you sounded out the word of the Lord, not only in Macedonia and Achaia,' your own province and the one next door to it, but also in every place your faith to Godward is spread abroad.' No man knows how far his influence will go. No man can tell how far his example may penetrate. Thessalonica was a great commercial city. So is Manchester. Hosts of people of all sorts came into it as they come here. There were many different circles which would be intersected by the lives of this Christian church, and wherever its units went they carried along with them the conviction that they had turned from idols to serve the living God, and to wait for His Son from heaven.
And so, dear brethren, if our witness is to be worth anything it must have this penetrating quality. There is a difference in sounds as there is a difference in instruments. Some of them carry further than others. A clear voice will fling words to a distance that a thick, mumbling one never can attain. One note will travel much further than another. Do you see to it that your notes are of the penetrating sort.
And then, again, the note should be a musical one. There is nothing to be done for God by harshness; nothing to be done by discords and gangling; nothing to be done by scolding and rebuke. The ordered sequence of melodious sound will travel a great deal further than unmusical, plain speech. You can hear a song at a distance at which a saying would be inaudible. Which thing is an allegory, and this is its lesson,--Music goes further than discord; and the witness that a Christian man bears will travel in direct proportion as it is harmonious, and gracious and gentle and beautiful.
And then, again, the note should be rousing. You do not play on a trumpet when you want to send people to sleep; dulcimers and the like are the things for that purpose. The trumpet means strung-up intensity, means a call to arms, or to rejoicing; means at any rate, vigour, and is intended to rouse. Let your witness have, for its utmost signification, Awake! thou that sleepest, and arise from the dead; and Christ shall give thee light.'
