If you look at the context, you will see that all the ways in which the word of the Lord is represented as sounding out from the Thessalonian Church were deeds, not words. The context supplies a number of them. Such as the following are specified in it: their work; their toil, which is more than work; their patience; their assurance; their reception of the word, in much affliction with joy in the Holy Ghost; their faith to Godward; their turning to God from idols, to serve and to wait.
That is all. So far as the context goes there might not have been a man amongst them who ever opened his mouth for Jesus Christ. We know not, of course, how far they were a congregation of silent witnesses, but this we know, that what Paul meant when he said, 'The whole world is ringing with the voice of the word of God sounding from you,' was not their going up and down the world shouting about their Christianity, but their quiet living like Jesus Christ. That is a louder voice than any other.
Ah! dear friends! it is with God's Church as it is with God's heavens; the 'stars in Christ's right hand' sparkle in the same fashion as the stars that He has set in the firmament. Of them we read: 'There is neither voice nor language, their speech is not heard'; and yet, as man stands with bared head and hushed heart beneath the violet abysses of the heavens, 'their line' (or chord, the metaphor being that of a stringed instrument) 'is gone out through all the earth, and their words to the end of the world.' Silent as they shine, they declare the glory of God, and proclaim His handiwork. And so you may speak of Him without speaking, and though you have no gift of tongues the night may be filled with music, and your lives be eloquent of Christ.
I do not mean to say that Christian men and women are at liberty to lock their lips from verbal proclamation of the Saviour they have found, but I do mean to say that if there was less talk and more living, the witness of God's Church would be louder and not lower; 'and men would take knowledge of us, that we had been with Jesus'; and of Jesus, that He had made us like Himself.
IV. And so, lastly, let me draw one other thought from this metaphor, which I hope you will not think fanciful playing with a figure; and that is the breath that makes the music.
If the Church is the trumpet, who blows it? God! It is by His Divine Spirit dwelling within us, and breathing through us, that the harsh discords of our natural lives become changed into melody of praise and the music of witness for Him. Keep near Christ, live in communion with God, let Him breathe through you, and when His Spirit passes through your spirits their silence will become harmonious speech; and from you 'will sound out the word of the Lord.'
In a tropical country, when the sun goes behind a cloud, all the insect life that was cheerily chirping is hushed. In the Christian life, when the Son of Righteousness is obscured by the clouds born of our own carelessness and sin, all the music in our spirit ceases, and no more can we witness for Him. A scentless substance lying in a drawer, with a bit of musk, will become perfumed by contact, and will bring the fragrance wherever it is carried. Live near God, and let Him speak to you and in you; and then He will speak through you. And if He be the breath of your spiritual lives, and the soul of your souls, then, and only then, will your lives be music, the music witness, and the witness conviction. And only then will there be fulfilled what I pray there may be more and more fulfilled in us as a Christian community, this great word of our text, 'from you sounded out,' clear, rousing, penetrating, melodious, 'the word of the Lord,' so that we, with our poor preaching, need not to speak anything.
