Strong appeals are made in our day to members of the Christian Church to engage actively in all kinds of Christian work. They are summoned to go forth aggressively upon the world's misery and sin. This has become a characteristic note of our time. Such appeals were needed. It is a shame that so many Christians have absolved themselves from the obligation to place at their Lord's service the aptitudes and the energies with which He has endowed them. Yet in this wholesale administration diversities are apt to be overlooked. Christians may be undervalued who do not possess qualities fitting them for the special activities; or, attempting these without much aptitude, and finding little success, they may be unduly cast down. It is important to lay stress on this. There are some, perhaps we should say many, who must come to the conclusion, if they judge aright, that their gifts and opportunities indicate for them, as their sphere, a somewhat narrow round of duties, mostly of that ordinary type which the common experience of human life supplies. But if they bring into these a Christian heart; if they use the opportunities they have; if they are watchful to please their Lord in the life of the family, the workshop, the market; if the purifying influence of the faith by which they live comes to light in the steady excellence of their character and course,--then they need have no sense of exclusion from the work of Christ and of His Church. They, too, do missionary work. Blameless, harmless, unrebuked, they are seen as lights in the world. They contribute, in the manner that is most essential of all, to the Church's office in the world. And their place of honour and reward shall be far above that of many a Christian busybody, who is too much occupied abroad to keep the light clear and bright at home. Blameless, then, harmless, unaspersed, must the children of God, His redeemed children, be. So will the light of Christian character come clearly out, and Christians will be "luminaries, holding forth the word of life."
