Paul wraps up his letter with commendations, greetings, and final words. The first of these is found here: a warm introduction to two faithful brothers.
Tychicus (7-8): Paul sent Tychicus to deliver this letter. He was a long-time companion of Paul's who knew his circumstances well. Thus, Paul sent him to give an update on their situation in Rome. Moreover, he was to "encourage your hearts" with the Word. In addition to giving an update, he was to give this encouragement. Paul calls him a "beloved brother" and commends him as "a faithful minister and fellow slave in the Lord." This man was dependable. The Word of God advanced through reliable men like Tychicus.
Onesimus (9): The second man, Onesimus, was to join Tychicus in informing the church. He was a Colossian native ("one of your number") and a slave who escaped from his master. While a fugitive in Rome, he was saved through Paul (Phm. 10) and became a "beloved brother," but more than that, a "faithful brother," even a personal minister to him (Phm. 13). But Paul returned him to his master. The will of God for slaves was clear: they must obey their master (3:22). God's Word always trumps our own wants/needs. Thus, Paul sent Onesimus to serve his master, and he willingly went. He was indeed faithful.
 In addition to Colossians, he delivered two more epistles on this trip: Ephesians and Philemon.
 During his third missionary journey (which begins in Acts 18:22-23), Tychicus and others accompanied Paul from Greece onward (Acts 20:1-4). He likely remained with Paul from then on until his Roman imprisonment.
 This update was for Paul and his companions (4:10-14). Tychicus updated others also (Eph. 6:21-22).
 In 2:2, this phrase describes the effect of the preaching of the Word (1:25-2:2). Tychicus was a capable minister of the Word whom Paul relied on to relieve other like ministers (2 Tim. 4:9-13; Tit. 3:12). The task of encouragement was given to him (not Onesimus), and it is best to see it as involving the ministry of the Word.
 "Servant" (NASB) is a "minister" (ESV). "Bond-servant" is the word for "slave." Paul used both phrases to describe another fellow worker, namely, Epaphras (1:7). Tychicus was a fellow minister like him.
