Paul’s ministry in Ephesus involved constant labor, many hardships, and deep anguish. He had taught the people in public and from house to house, instructing and warning them. The Jews had opposed him at every turn. And while he was battling against opposition, he was carrying a heavy burden on his heart for all the churches. News of apostasy in some of the churches caused him deep sorrow. He spent many sleepless nights in earnest prayer as he learned of how people were trying to undo his work. 4TC 153.3
As he had opportunity, he wrote to the churches, giving correction, counsel, warnings, and encouragement. In these letters he sometimes gave glimpses of his sufferings in the service of Christ. Beatings and imprisonment, cold and hunger and thirst, dangers by land and by sea, in the city and in the wilderness, from his own countrymen, from the heathen, and from false believers—all this he endured for the gospel. He was “defamed,” “reviled,” made “the offscouring of all things,” “perplexed,” “persecuted,” “hard pressed on every side,” “in jeopardy every hour,” “always delivered to death for Jesus’ sake.” 4TC 153.4
The brave apostle almost lost heart. But he looked to Calvary and with new spirit went forward to spread the knowledge of Jesus the Crucified. He was walking the blood-stained path Christ had traveled before him. He wanted no release from the warfare until it would be time for him to lay his armor down at the feet of his Redeemer. 4TC 153.5
