I have fought the good fight, I have finished the race, I have kept the faith.
(2 TIMOTHY 4:7, ESV)
in previous verses of chapter 4, Paul had exhorted Timothy to preach the word, to endure all for the sake of the sake of the gospel. Paul, himself, had put his life's effort into completing the "course" which God had set before him and now his time for departure had come. (death) Paul left nothing undone. He remained committed to the faith.
Faithfulness: a long obedience in the same direction. (Cole Huffman)
No cuppa mediocri-TEA served by Paul. He chose a cuppa full commi-TEA-ment until the end. He had poured his life into Timothy---for the sake of the gospel.
