Let us take a glance at Henry Martyn. Leaving England as a young man in feeble health, for six years he worked against fearful odds in India. There in that disease-ladened land and in Persia he pursued his arduous task of learning three languages utterly adverse, such as Hindustani, Arabic, and Persian. In these three languages he translated the entire New Testament in six years. This is one of the most astonishing of intellectual feats on record. Besides these translations he made others and when we remember that he was burning up with consumptive's fever, and yet kept right on till, in order to perfect his translation in Persian, he made a trip to that country, and crossing burning, sand deserts with his own body literally burning up with fever, he was surely a living sacrifice. His passionate love for the Savior and the souls of lost men, made him suffer on in weakness and sickness, until the short candle of his life consuming at both ends finally flickered out in that faraway foreign land between Persia and the western shore, and where a lone headstone marked the spot where one of God's sainted heroes lay down and died. How small it makes me feel as I write these lines! Another example is that of David Brainerd, the apostle to the Indians before the colonies became independent. This young man, who died in his thirtieth year in the home of Jonathan Edwards, was one of those early pioneers of gospel work among the wild and pagan Indians. He was another living sacrifice, very feeble in body, dying by inches with consumption, yet toiled on without murmuring, and praying till his body would be bathed in perspiration, he battled almost against hope till finally God gave him marvelous success among those benighted savages. A few lines from the journal of this marvelous man of prayer may stir up more of a spirit of prayer and self-sacrifice in the reader: "June 14, 1742.
