The greatest of human teachers, Paul accepted the lowliest as well as the highest duties. He recognized the necessity of labor for the hand as well as for the mind, and he wrought at a handicraft for his own support. His trade of tent-making he pursued while daily preaching the gospel in the great centers of civilization. “These hands,” he said, at parting with the elders of Ephesus, “have ministered unto my necessities, and to them that were with me.”[70] [Sidenote: _Sympathy and Insight_] While he possessed high intellectual endowments, the life of Paul revealed the power of a rarer wisdom. Principles of deepest import, principles concerning which the greatest minds of his time were ignorant, are unfolded in his teachings and exemplified in his life. He had that greatest of all wisdom, which gives quickness of insight and sympathy of heart, which brings man in touch with men, and enables him to arouse their better nature and inspire them to a higher life. Listen to his words before the heathen Lystrians, as he points them to God revealed in nature, the Source of all good, who “gave us rain from heaven, and fruitful seasons, filling our hearts with food and gladness.”[71] [Sidenote: _Mastership_] See him in the dungeon at Philippi, where, despite his pain-racked body, his song of praise breaks the silence of midnight. After the earthquake has opened the prison doors, his voice is again heard, in words of cheer to the heathen jailer, “Do thyself no harm; for we are all here,”[72]—every man in his place, restrained by the presence of one fellow-prisoner. And the jailer, convicted of the reality of that faith which sustains Paul, inquires the way of salvation, and with his whole household unites with the persecuted band of Christ’s disciples. [Sidenote: _In Advance of His Age_] See Paul at Athens before the council of the Areopagus, as he meets science with science, logic with logic, and philosophy with philosophy. Mark how, with the tact born of divine love, he points to Jehovah as the “Unknown God,” whom his hearers have ignorantly worshiped; and in words quoted from a poet of their own he pictures Him as a Father whose children they are. Hear him, in that age of caste, when the rights of man as man were wholly unrecognized, as he sets forth the great truth of human brotherhood, declaring that God “hath made of one blood all nations of men for to dwell on all the face of the earth.” Then he shows how, through all the dealings of God with man, runs like a thread of gold His purpose of grace and mercy. He “hath determined the times before appointed, and the bounds of their habitation; that they should seek the Lord, if haply they might feel after Him, and find Him, though He be not far from every one of us.”[73]
