If the Christian worker longs to benefit the poor slum district in which he is located, he must be prepared to live amongst the people and expend himself. Presently, in his hollow cheeks, his sallow complexion, his attenuated form, his diminishing strength, you will see that he is paying the price for his 100-candle illuminating power, because he is being consumed. Every successful worker for God must learn that lesson. You must be prepared to suffer; you can only help men when you die for them. If you desire to save others you cannot save yourself; you must be prepared to fall into the ground and die, if you would not abide alone: there must be with you, as with Paul, the decaying of the outward man, that the inward man may be renewed day by day. You must be prepared to say with him, "Death worketh in us, but life in you." _If you burn, you will shine_. The burning and the shining do not always go together; often the burning goes on a long time without much illumination resulting from the expenditure. Those who are rich in gifts and natural endowments cast in much, and the poor cast in all their living; this they continue to do, year after year, and none seems to heed the awful cost at which their testimony is given. Moreover, to use a well-known phrase, the game hardly seems worth the candle. The area they influence is so limited, the souls affected so few, the glimmer of their light, like a street-lamp in a fog, hardly reaches across the street or to the ground. Sometimes it appears only to make the darkness denser and thicker. In many cases, the saints of God have burnt down to the last film of vital energy and expired, and there has been no shining that the world has taken cognisance of. Their bitter complaint has been, "I have laboured in vain; I have spent my strength for nought, and in vain." But even these shall shine. They shall shine as the stars for ever and ever in that world where all holy and faithful souls obtain their due.
