Romans 12:14-19
Bless your enemies; no cursing under your breath. Laugh with your happy friends when they're happy; share tears when they're down. Get along with each other; don't be stuck-up. Make friends with nobodies; don't be the great somebody.

Don't hit back; discover beauty in everyone. If you've got it in you, get along with everybody. Don't insist on getting even; that's not for you to do. "I'll do the judging," says God. "I'll take care of it."
