After years of service in Africa, the missionary Robert Moffat returned to Scotland to recruit helpers. When he arrived at church one cold wintry night, he was dismayed that only a small group had come out to hear him. What bothered him even more was that the only people in attendance were ladies. Although he was grateful for their interest, he had hoped to challenge men. He had chosen as his text Proverbs 8:4, “Unto you, O men, I call.” In his discouragement, he almost failed to notice one small boy in the loft pumping the bellows of the organ. Moffat felt frustrated as he gave the message, for he realized that very few women could be expected to undergo the rigorous life in undeveloped jungles. But God works in mysterious ways. Although no one volunteered that evening, the young fellow assisting the organist was deeply moved by the challenge. As a result, he promised God he would follow in the footsteps of this pioneer missionary. And he remained true to his vow. When he grew up, he went and ministered to the unreached tribes of Africa. His name was David Livingstone! More on his life and manuscripts
