Paul writes 2 Timothy, his last letter
Imprisoned again in Rome and expecting death, Paul wrote to Timothy, urging him to guard the gospel, endure hardship, and preach the word, and asking him to come quickly and bring Mark, his cloak, and the scrolls.
I have fought the good fight. I have finished the course. I have kept the faith.
2 Timothy 4:7 (World English Bible)
Most of his companions had left; only Luke was with him (2 Timothy 4:11). Paul wrote that all Scripture is God-breathed (2 Timothy 3:16) and looked beyond his death to the crown of righteousness the Lord would give him.
