That's what friends are for!

One of the joys of the letters that we have in the New Testament is the personal information that they give us. 2 Timothy is a case in pont. Paul is in prison awaiting his execution and yet the one thing that is on his mind is his friends, either passing on greetings from them, or wanting to see them before he dies. We even find him remembering where he lost his coat and asking for it back!
It's the details such as this which make the New Testament come alive with REAL people (most of these characters can be cross-referenced to Acts and other NT books)
Read these last words from Paul to Timothy in 2 Timothy chapter 4 and get a real feel for the extended fellowship that existed then (and also the fact that there was also division and those acting in their own best interests - nothing changes!)

Paul’s Final Words

 ⁹ Timothy, please come as soon as you can. ¹⁰ Demas has deserted me because he loves the things of this life and has gone to Thessalonica. Crescens has gone to Galatia, and Titus has gone to Dalmatia. ¹¹ Only Luke is with me. Bring Mark with you when you come, for he will be helpful to me in my ministry. ¹² I sent Tychicus to Ephesus. ¹³ When you come, be sure to bring the coat I left with Carpus at Troas. Also bring my books, and especially my papers. ¹⁴ Alexander the coppersmith did me much harm, but the Lord will judge him for what he has done. ¹⁵ Be careful of him, for he fought against everything we said.
 ¹⁶ The first time I was brought before the judge, no one came with me. Everyone abandoned me. May it not be counted against them. ¹⁷ But the Lord stood with me and gave me strength so that I might preach the Good News in its entirety for all the Gentiles to hear. And he rescued me from certain death. ¹⁸ Yes, and the Lord will deliver me from every evil attack and will bring me safely into his heavenly Kingdom. All glory to God forever and ever! Amen.

Paul’s Final Greetings

 ¹⁹ Give my greetings to Priscilla and Aquila and those living in the household of Onesiphorus. ²⁰ Erastus stayed at Corinth, and I left Trophimus sick at Miletus. ²¹ Do your best to get here before winter. Eubulus sends you greetings, and so do Pudens, Linus, Claudia, and all the brothers and sisters.
