89. In his first journey Paul may be said to have been only trying his wings; for his course, adventurous though it was, only swept in a limited circle round his native province. In his second journey he performed a far more distant and perilous flight. Indeed, this journey was not only the greatest he achieved but perhaps the most momentous recorded in the annals of the human race. In its issues it far outrivaled the expedition of Alexander the Great, when he carried the arms and civilization of Greece into the heart of Asia, or that of Caesar, when he landed on the shores of Britain, or even the voyage of Columbus, when he discovered a new world. Yet, when he set out on it, he had no idea of the magnitude which it was to assume or even the direction which it was to take. After enjoying a short rest at the close of the first journey, he said to his fellow-missionary, "Let us go again and visit our brethren in every city where we have preached the word of the Lord and see how they do." It was the parental longing to see his spiritual children which was drawing him; but God had far more extensive designs, which opened up before him as he went forward.
90. Separation from Barnabas.--Unfortunately the beginning of this journey was marred by a dispute between the two friends who meant to perform it together. The occasion of their difference was the offer of John Mark to accompany them. No doubt when this young man saw Paul and Barnabas returning safe and sound from the undertaking which he had deserted, he recognized what a mistake he had made; and he now wished to retrieve his error by rejoining them. Barnabas naturally wished to take his nephew, but Paul absolutely refused. The one missionary, a man of easy kindliness, urged the duty of forgiveness and the effect which a rebuff might have on a beginner; while the other, full of zeal for God, represented the danger of making so sacred a work in any way dependent on one who could not be relied upon, for "confidence in an unfaithful man in time of trouble is like a broken tooth or a foot out of joint."
We cannot now tell which of them was in the right or if both were partly wrong. Both of them, at all events, suffered for it: Paul had to part in anger from the man to whom he probably owed more than to any other human being; and Barnabas was separated from the grandest spirit of the age.
91. They never met again. This was not due, however, to an unchristian continuation of the quarrel; for the heat of passion soon cooled down and the old love returned. Paul mentions Barnabas with honor in his writings, and in the very last of his Epistles he sends for Mark to come to him at Rome, expressly adding that he is profitable to him for ministry--the very thing he had disbelieved about him before. In the meantime, however, their difference separated them. They agreed to divide between them the region they had evangelized together. Barnabas and Mark went away to Cyprus; and Paul undertook to visit the churches on the mainland. As companion he took with him Silas, or Silvanus, in the place of Barnabas; and he had not proceeded far on his new journey when he met with one to take the place of Mark. This was Timothy, a convert he had made at Lystra in his first journey; he was youthful and gentle; and he continued a faithful companion and a constant comfort to the apostle to the end of his life.
92. Unrecorded Work.--In pursuance of the purpose with which he had set out, Paul began this journey by revisiting the churches in the founding of which he had taken part. Beginning at Antioch and proceeding in a northwesterly direction, he did this work in Syria, Cilicia and other parts, till he reached the center of Asia Minor, where the primary object of his journey was completed. But, when a man is on the right road, all sorts of opportunities open up before him. When he had passed through the provinces which he had visited before, new desires to penetrate still farther began to fire his mind, and Providence opened up the way.
