"The trials and anxieties that Paul had endured had preyed upon his physical powers. The infirmities of age were upon him. He felt that he was now doing his last work, and, as the time of his labor grew shorter, his efforts became more intense. There seemed to be no limit to his zeal. Resolute in purpose, prompt in action, strong in faith, he journeyed from church to church, in many lands, and sought by every means within his power to strengthen the hands of the believers, that they might do faithful work in winning souls to Jesus, and that in the trying times upon which they were even then entering, they might remain steadfast to the gospel, bearing faithful witness for Christ. AA 488.1"
"I have fought a good fight, I have finished my course, I have kept the faith:"
The EGW passage describes Paul's declining health and intensified efforts as he neared the end of his life. The 2 Timothy verse is Paul's declaration that he has finished his course and kept the faith, reflecting a similar sentiment of nearing the end of his ministry.
"Therefore watch, and remember, that by the space of three years I ceased not to warn every one night and day with tears."
Both passages emphasize Paul's dedication to warning and strengthening believers. The EGW passage describes Paul's efforts to strengthen believers in the face of trying times, while the Acts verse highlights Paul's constant warning to believers with tears.
