Closing words (6:21-24).
‘But that you also may know my affairs, how I do, Tychicus, the beloved brother and faithful minister in the Lord, will make all things known to you, whom I have sent to you for this very purpose, that you may know our state and that he may comfort your hearts.'
Tychicus is also mentioned as the bearer of the letter to the Colossians (Colossians 4:7 see also 2 Timothy 4:12; Titus 3:12). He is a highly trusted friend and ‘beloved brother'. But his greatest commendation is that he is a faithful servant of Christ. He will give full information about Paul's position and circumstances. This indeed is why he has spared him, so that he may comfort and strengthen the churches.
The lack of numerous greetings would seem to confirm that the Ephesian letter was intended for a wider circle.
