“Owe no one anything, except to love each other, for the one who loves another has fulfilled the law” (v8). Paul told the believers not to complicate their lives by being on the wrong side of the law. Even under pagan Roman government, Paul taught them to respect their leaders, pay their taxes, and obey the laws which did not directly conflict with Jesus’ teaching (v1-3). These instructions were followed by the positive command to “love one another.” It is not enough to avoid wrongdoing; love for God compels us to positive action.
Our time is limited (v11). “So then let us cast off the works of darkness and put on the armor of light” (v12).
