83. At Perga, the starting-point of this second half of the journey, a misfortune befell the expedition: John Mark deserted his companions and sailed for home. It may be that the new position assumed by Paul had given him offense, though his generous uncle felt no such grudge at that which was the ordinance of nature and of God. But it is more likely that the cause of his withdrawal was dismay at the dangers upon which they were about to enter. These were such as might well strike terror even into resolute hearts. Behind Perga rose the snow-clad peaks of the Taurus Mountains, which had to be penetrated through narrow passes, where crazy bridges spanned the rushing torrents, and the castles of robbers, who watched for passing travelers to pounce upon, were hidden in positions so inaccessible that even the Roman army had not been able to exterminate them. When these preliminary dangers were surmounted, the prospect beyond was anything but inviting: the country to the north of the Taurus was a vast tableland, more elevated than the summits of the highest mountains in this country, and scattered over with solitary lakes, irregular mountain masses and tracts of desert, where the population was rude and spoke an almost endless variety of dialects. These things terrified Mark, and he drew back. But his companions took their lives in their hand and went forward. To them it was enough that there were multitudes of perishing souls there, needing the salvation of which they were the heralds; and Paul knew that there were scattered handfuls of his own people in these remote regions of the heathen. 84. Can we conceive what their procedure was like in the towns they visited? It is difficult, indeed, to picture it to ourselves. As we try to see them with the mind's eye entering any place, we naturally think of them as the most important personages in it; to us their entry is as august as if they had been carried on a car of victory. Very different, however, was the reality. They entered a town as quietly and as unnoticed as any two strangers who may walk into one of our towns any morning. Their first care was to get a lodging; and then they had to seek for employment, for they worked at their trade wherever they went. Nothing could be more commonplace. Who could dream that this travel-stained man, going from one tentmaker's door to another, seeking for work, was carrying the future of the world beneath his robe!
