That is drawn from a consideration of the office and function of Christian men. Their position in the midst of a crooked and perverse generation' devolves on them a duty in relation to that generation. They are to appear as lights in the world.' The relation between them and it is not merely one of contrast, but on their parts one of witness and example. The metaphor of light needs no explanation. We need only note that the word, are seen' or appear,' is indicative, a statement of fact, not imperative, a command. As the stars lighten the darkness with their myriad lucid points, so in the divine ideal Christian men are to be as twinkling lights in the abyss of darkness. Their light rays forth without effort, being an involuntary efflux. Possibly the old paradox of the Psalmist was in the Apostle's mind, which speaks of the eloquent silence, in which there is no speech nor language, and their voice is not heard,' but yet their line has gone out through all the earth, and their words unto the end of the world.'
Christian men appear as lights by holding forth the word of life.' In themselves they have no brightness but that which comes from raying out the light that is in them. The word of life must live, giving life in us, if we are ever to be seen as lights in the world.' As surely as the electric light dies out of a lamp when the current is switched off, so surely shall we be light only when we are' in the Lord.' There are many so-called Christians in this day who stand tragically unaware that their lamps are gone out.' When the sun rises and smites the mountain tops they burn, when its light falls on Memnon's stony lips they breathe out music, Arise, shine, for thy light has come.'
Undoubtedly one way of holding forth the word of life' must be to speak the word, but silent living blameless and harmless' and leaving the secret of the life very much to tell itself is perhaps the best way for most Christian people to bear witness. Such a witness is constant, diffused wherever the witness-bearer is seen, and free from the difficulties that beset speech, and especially from the assumption of superiority which often gives offence. It was the sight of your good deeds' to which Jesus pointed as the strongest reason for men's glorifying your Father.' If we lived such lives there would be less need for preachers. If any will not hear the word they may without the word be won.' And reasonably so, for Christianity is a life and cannot be all told in words, and the Gospel is the proclamation of freedom from sin, and is best preached and proved by showing that we are free. The Gospel was lived as well as spoken. Christ's life was Christ's mightiest preaching.
The word was flesh and wrought
If we keep near to Him we too shall witness, and if our faces shine like Moses' as he came down from the mountain, or like Stephen's in the council chamber, men will take knowledge of us that we have been with Jesus.'
