What does the Bible say about Boundaries?

⁹Let love be without hypocrisy. Abhor that which is evil. Cling to that which is good. ¹⁰In love of the brothers be tenderly affectionate to one another; in honor preferring one another; ¹¹not lagging in diligence; fervent in spirit; serving the Lord; ¹²rejoicing in hope; enduring in troubles; continuing steadfastly in prayer; ¹³contributing to the needs of the saints; given to hospitality. ¹⁴Bless those who persecute you; bless, and don’t curse. ¹⁵Rejoice with those who rejoice. Weep with those who weep. ¹⁶Be of the same mind one toward another. Don’t set your mind on high things, but associate with the humble. Don’t be wise in your own conceits. ¹⁷Repay no one evil for evil. Respect what is honorable in the sight of all men. ¹⁸If it is possible, as much as it is up to you, be at peace with all men.
