Set your mind to heavenly and godly things, not the old sinful ways of living. No impurity, lying, coveting, anger or division and despising between social classes.
Put on kindness, compassion, forgiveness and love, which all come by the peace of Christ, which comes by His Word. Do everything for Jesus, and with His name in mind. Family life should be loving, according to the roles given each.
Pray thankfully. Be wise in how you act and speak to unbelievers.
Tychicus and Onesimus (Philemon's slave!) will tell you the news.
John Mark greets you (the one who left Saul and Barnabas on their first journey in Acts 13:13; 15:37-39), as does Doctor Luke.
How this is about Jesus
In the call to put off sin and put on righteousness, we find Jesus at the heart of that righteousness (3:15-16).
To get rid of sin we have to replace it with something more powerful, and the only option is Jesus. Thomas Chalmers called this the expulsive power of a new affection.
Paul's invitation to welcome John Mark is stunning - he had separated from Barnabas he was so unwilling to take him along on their second journey. Now he commends him to the Colossians.
Demas leaves Paul later (2 Timothy 4:10).
Life is made up of unexpected reconciliations and abandonments.
