Colossians 4:7-8

Paul sent Tychicus with this letter for two primary purposes. He wanted to provide more information about himself and his present ministry than he felt led to record in this letter. He also wanted to encourage the Colossians. In relation to all other Christians Tychicus was a beloved brother. In relation to Christ he was a faithful servant. In relation to Paul he was a fellow-bondslave either both as a prisoner of Rome and to the will of God, or just to the will of God. Tychicus’ name occurs five times in association with Paul in the New Testament (Acts 20:4; Ephesians 6:21; Colossians 4:7; Titus 3:12; 2 Timothy 4:12).
