Let your love be real: fight against everything that is evil; encourage and nurture everything that is good.
Let your love be mutual affection; outdo each other in respecting and encouraging each other.
Do not grow lukewarm. Be in the Spirit and be ardently in love. Serve the Lord with how you live. Celebrate hope with others. Be patient while you go through hell. When you say and walk your prayers: resist; insist; persist; and enlist. Give to those who have less than you. Be fully hospitable to space aliens, immigrants, and other strangers. Bless those who dump on you; if you bless them instead of cursing them, it will drive them nuts. Party with those who are celebrating, and cry with those who are mourning.
Be part of a civilized society and live together in harmony. Don't have a stick up your butt; hang with some lowlifes once in a while - Jesus did. Always remember and never forget, you're not nearly as smart as you think you are. People know!
Be in the world but not of it; do not fight violence and hate with violence and hate. For God's sake, think before you open your mouth the next time! If it is at all remotely feasibly conceivably possible, live peaceable with everyone. Never, never, ever "get even", "pay them back", or "show them". NEVER. Life is not meant to be a Revenge Of The ________ movie! Let God take care of the wrath and vengeance thing.
In the meanwhile, if your enemy is hungry, invite them over for supper. If they are thirsty, take them out and buy them a drink. If you are nice to someone (specially in public) who can't stand you, you get to sit back and watch their face turn bright red with impotent fury and/or shame.
The world sucks sometimes, but don't let evil get you down or turn you to the dark-side - overwhelm evil (drown it) with goodness, kindness, and love.
