The duty to which he exhorts in this verse, is a peaceable and quiet behaviour towards all men, as well infidels as Christians; those who are bad, as well as those who are good. The like exhortations we have, Hebrews 12:14. And to the discharge of this duty he annexeth a double limitation; first: If it be possible; secondly: As much as lieth in you: q.d. It may so fall out, that some men are of such froward and unpeaceable tempers, that it is impossible to live peaceably with them, or by them: or such conditions of peace may be offered as are not lawful for you to accept; it will not stand with the truth and glory of God, and with a good conscience, to agree with them. But, however, do your part, let there be no default in you why you should not live in peace with all men whatsoever.
