With the thought of the missionary and also of the living sacrifice before us, we have the perfect combination of the two in the self-sacrificing experience of some of the early pioneers in the foreign lands. We, in the home lands, can scarcely realize the toils and hardships and dangers that some of these heroes of the cross waded through. We think of the dauntless Livingstone, who penetrated Africa's jungles in order to plant the gospel in that benighted region. Lost to home and the world for years, no wonder people considered him worth looking up, and sending a Stanley in search for him. But he was doing a work which would open up nations to hear the Word of life. Though he had to bury his loved one on the bank of the Zambesi, yet "with undaunted courage, he set his face toward new paths." How the natives loved this man--this living sacrifice. He was the means in God's hands of bringing them light for darkness, comfort for sorrow, life for death. He was the foe of the slave stealers, and delivered the poor helpless mortals from their grasp. He toiled on in solitude, and gave his very life to make a way to this dark and heathen world. Finally, far from the shore, and thousands of miles from home, he took sick. He was a man of prayer, and one morning when the native men looked into his abode, they found only the body of this devoted follower of the Lamb; he was dead on his knees. Those dusky, devoted souls determined to do the best they could in memory of their apostle, and knowing that his great, loving heart was centered in Africa, they took out his heart and buried it beneath a tree. They then let the hot sun dry the body and those loyal hands carried the remains many, many miles to the seashore, where, what was left of the faithful missionary was shipped to England. And now, with the heart of David Livingstone in the middle of Africa, his body in Westminster Abbey, his soul in heaven, we have an example of the grace of God in helping a man to give up his life for a lost world.
