It was a somewhat similar incident, though not preceded by any such previous backsliding--a similar manifestation of the magical power of trust--that took place in the life of a more modern David, one who in serving God and doing good to man had to encounter a life of wandering, privation, and danger seldom surpassed--the African missionary and explorer, David Livingstone. In the course of his great journey from St. Paul de Loanda on the west coast of Africa to Quilimane on the east, he had to encounter many an angry and greedy tribe, whom he was too poor to be able to pacify by the ordinary method of valuable presents. On one occasion, in the fork at the confluence of the river Loangwa and the river Zambesi, he found one of those hostile tribes. It was necessary for him to have canoes to cross--they would lend him only one. In other respects they showed an attitude of hostility, and the appearances all pointed to a furious attack the following day. Livingstone was troubled at the prospect,--not that he was afraid to die, but because it seemed as if all his discoveries in Africa would be lost, and his sanguine hopes for planting commerce and Christianity among its benighted and teeming tribes knocked on the head. But he remembered the words of the Lord Jesus Christ, "Go ye therefore into all the world, and preach the gospel unto every creature, and lo, I am with you alway, even unto the end of the world." On this promise he rested, and steadied his fluttering heart. "It is the word of a gentleman," he said, "the word of one of the most perfect honour. I will not try, as I once thought, to escape by night, but I will wait till to-morrow, and leave before them all. Should such a man as I be afraid? I will take my observations for longitude tonight, though it should be my last. My mind is now quite at rest, thank God." He waited as he had said, and next morning, though the arrangements of the natives still betokened battle, he and his men were allowed to cross the river in successive detachments, without molestation, he himself waiting to the last, and not a hair of their heads being hurt. It was a fine instance of a believing Christian strengthening himself in his God. When faith is genuine, and the habit of exercising it is active, it can remove mountains. The first result of the restored feeling of trust in David was his giving honour to God's appointed ordinance by asking counsel of Him, through Abiathar the priest, as to the course he should follow. It is the first time we read of him doing so since he left his own country. At first one wonders how he could have discontinued so precious a means of ascertaining the will of God and the path of duty. But the truth is, when a man is left to himself he cares for no advice or direction but his own inclination. He is not desirous to be led; he wishes only to go comfortably. Indifference to God's guidance explains much neglect of prayer.
