The chapter opens with a charge. Paul, writing from a Roman prison, places Timothy under the solemn witness of God and Christ Jesus, who will judge the living and the dead. The charge is given by Christ's appearing and his kingdom. There is no preamble, no softening. The command is direct: preach the word.
Paul insists on urgency in season and out of season. Timothy is to reprove, rebuke, and exhort with all patience and teaching. The reason is plain. A time will come when people will not endure sound doctrine. They will gather teachers who tell them what they want to hear, turning from the truth to myths.
Timothy is told to be sober in all things, to suffer hardship, to do the work of an evangelist, and to fulfill his ministry. The charge is not abstract. It is tied to Paul's own situation. He writes that he is already being poured out as a drink offering, and the time of his departure is at hand.
Paul then speaks of his own course. He has fought the good fight, finished the race, kept the faith. A crown of righteousness is laid up for him, which the Lord, the righteous judge, will give him on that day. And not only to him, but to all who have loved Christ's appearing.
The tone shifts to practical requests. Paul asks Timothy to come quickly. Demas has deserted him, having loved this present world, and gone to Thessalonica. Crescens has gone to Galatia, Titus to Dalmatia. Only Luke remains with Paul.
Paul tells Timothy to pick up Mark and bring him, because Mark is useful for ministry. Tychicus has been sent to Ephesus. Paul asks for the cloak he left at Troas with Carpus, and the books, especially the parchments. These are not sentimental requests. They are the tools of a man who still intends to work.
Alexander the coppersmith did Paul much harm. The Lord will repay him according to his works. Paul warns Timothy to be on guard against Alexander, who strongly opposed their message. At Paul's first defense, no one stood with him. Everyone deserted him. Paul prays that it not be held against them.
But the Lord stood by Paul and strengthened him, so that through him the message might be fully proclaimed and all the Gentiles might hear. Paul was delivered from the lion's mouth. He is confident the Lord will rescue him from every evil deed and bring him safely into his heavenly kingdom. To him be glory forever.
Paul sends greetings to Prisca and Aquila, and to the household of Onesiphorus. Erastus stayed in Corinth. Trophimus was left sick at Miletus. Paul urges Timothy to come before winter. Eubulus, Pudens, Linus, Claudia, and all the brothers send greetings. The chapter ends with a blessing: the Lord be with your spirit. Grace be with you.
