"Tell Archippus: 'See to it that you complete the work you have received in the Lord.'" NIV translation
In his letter to Philemon, Paul called Archippus "our fellow soldier" and he was evidently a part of the local church that met in Philemon's home. Here, Paul urges him to complete the work that God had given him. The same message goes for each and every one of us, as Christians, in that we have all been given work to do by the Lord.
"I, Paul, write this greeting in my own hand. Remember my chains. Grace be with you." NIV translation
Paul ends this letter with a call to stay focused on the main thing which is the grace of God. He asked them to remember that he was in chains for the gospel but still God was using him in a mighty way. The same is true for us, in that, no matter what our circumstances are, God has a plan, a purpose, and other people (team members) to help us to do the work that He has laid out for us.
