But this was not all, or nearly all, the burden the Apostle carried. He had to be perpetually on the alert against Jewish plots. We hear nothing directly of Jewish attempts on his life or liberty during the period of just three years which he spent on this prolonged visit. We might be sure, however, from our previous experience of the synagogues, that he must have run no small danger in this direction; but then when we turn to the same address we hear something of them. He is recalling to the minds of the Ephesian elders the circumstances of his life in their community from the beginning, and he therefore appeals thus: "Ye yourselves know from the first day that I set foot in Asia, after what manner I was with you all the time, serving the Lord with all lowliness of mind, and with tears, _and with trials which befell me with plots of the Jews_." Ephesus again was a great field wherein he personally worked; it was also a great centre for missionary operations which he superintended. It was the capital of the province of Asia, the richest and most important of all the Roman provinces, teeming with resources, abounding in highly civilised and populous cities, connected with one another by an elaborate network of admirably constructed roads. Ephesus was cut out by nature and by art alike as a missionary centre whence the gospel should radiate out into all the surrounding districts. And so it did. "All they which dwelt in Asia heard the word of the Lord, both Jews and Greeks," is the testimony of St. Luke with respect to the wondrous progress of the gospel, not in Ephesus alone, but also throughout all the province, a statement which we find corroborated a little lower down in the same nineteenth chapter by the independent testimony of Demetrius the silversmith, who, when he was endeavouring to stir up his fellow-craftsmen to active exertions in defence of their endangered trade, says, "Ye see and hear that not alone at Ephesus, but almost throughout all Asia, this Paul hath persuaded and turned away much people." St. Paul's disciples laboured, too, in the other cities of Asia, as Epaphras for instance in Colossæ. And St. Paul himself, we may be certain, bestowed the gifts and blessings of his apostolic office by visiting these local Churches, as far as he could consistently with the pressing character of his engagements in Ephesus.[190] But even the superintendence of vast missions throughout the province of Asia did not exhaust the prodigious labours of St. Paul. He perpetually bore about in his bosom anxious thoughts for the welfare, trials, and sorrows of the numerous Churches he had established in Europe and Asia alike. He was constant in prayers for them, mentioning the individual members by name, and he was unwearied in keeping up communications with them, either by verbal messages or by written epistles, one specimen of which remains in the First Epistle to the Corinthians, written to them from Ephesus, and showing
