Joh 1:14-17 proclaims the character of Jesus Christ -- Grace and Truth. Epaphras was imprisoned with Paul in Rome after seeking his guidance on the divisions in the Colossian church (Phm 1:23). We know several things about Epaphras' character. He was a teacher; faithful to his gift; and a prayer warrior (Col 4:12; Col 1:6). Our character is built as illustrated in these verses: Jam 4:7; Gal 5:16; 1Jo 5:4-5; Rom 6:14; Rom 8:37; 1Co 4:2; Jud 1:22-23.
Paul never met the Colossians but wrote to them from a Roman prison around 62 AD to counter misconceptions of his day. It magnifies the character of Jesus Christ more than any other book in the New Testament, and counters misconceptions of our day as well. The key verse may well be Col 1:18 "...that in all things, He might have preeminence."
