If it be possible, as much as lies in you, live peaceably with all men.
Read Chapter 12
Paul wants everyone who serves God’s righteousness to be peaceful….The person who is not peaceful is the one who has rejected the law of God and who follows his own law instead…. Even if the other person is not a lover of peace, you should want to be peaceful insofar as you can be. Commentary on Paul’s Epistles.
If it be possible. Have peace with all. That is, if it can be without prejudice to truth or justice And even when others wrong you, seek not to revenge yourselves, but leave your cause to God. Do good offices even to those that do evil to you. (Witham)
