Ephesians 4:1

"Therefore" or "then" refers to what Paul had said in chapters 1-3. To walk worthily or in balance means to harmonize one’s conduct with his or her calling. Calling here refers to God’s calling to live in unity as Jews and Gentiles in the church (Ephesians 2:13-16). To walk worthily then would involve behaving in a united way, living in unity with Jewish brethren if one is a Gentile or vice versa in the church. By referring to himself as the Lord’s prisoner again (Ephesians 3:1), Paul reminded his readers of his authority to urge them to live this way. He was in prison because he had followed God’s will faithfully.
