Romans 12:17-18
(17) Recompense to no man evil for evil. Provide things honest in the sight of all men.
(18) If it be possible, as much as lieth in you, live peaceably with all men.
The exhortations in verses 17-21 relate primarily to believers’ relationships with unbelievers, speaking as they do of those who do evil toward believers (v. 17) and are the “enemy” of believers (v. 20). The Old Testament principle of justice was “eye for eye” (Ex. 21:24), but Paul commanded, Do not repay anyone evil for evil (cf. 1 Peter 3:9). On the positive side Christians are to do what is right (kala, “beautiful,” used here in the ethical sense of good, noble, and honorable). Paul then commanded believers, Live at peace with everyone (cf. “live in harmony with one another,” Rom. 12:16). But recognizing that limits exist, Paul included the words, If it is possible, as far as it depends on you. Harmony with others may not always be achievable, but believers should not be responsible for that lack of peace (cf. Matt. 5:9).
