Paul instructs the Colossian church concerning the nearby church in Laodicea. He then picks up the pen and adds his own personal greetings.
Paul didn't serve alone. A team of six exemplary men surrounded him. These brothers, like Paul, cared for the Colossians and sent their warm greetings.
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.
Having addressed each of the household relationships, Paul now turns his attention back to the whole church to give his final exhortations.
Doing all things in the name of the Lord has no limits (3:17). This even applies to slaves and masters. Slaves obey, and masters show fairness.
The comprehensive command to do all things in the name of the Lord is now applied to everyday household relationships. The Lord wants our social relationships to be sanctified. Paul first deals with marriage and family.
