In his book “Almost Everything I Need to Know about God I Learned in Sunday School”, Rob Parsons offers this practical application of Romans 12. “Take your everyday, ordinary life—your sleeping, eating, going-to-work, and walking-around life—and place it before God as an offering. Embracing what God does for you is the best thing you can do for Him. Don’t become so well-adjusted to your culture that you fit into it without even thinking. Instead, fix your attention on God. You’ll be changed from the inside out.
If you preach, just preach God’s Message, nothing else; if you help, just help, don’t take over; if you teach, stick to your teaching; if you give encouraging advice, be careful that you don’t get bossy; if you’re put in charge, don’t manipulate; if you are called to give aid to people in distress, keep your eyes open and be quick to respond; if you work with the disadvantaged, don’t let yourself get irritated with them or depressed by them. Keep a smile on your face.
Love from the center of who you are; don’t fake it. Run for dear life from evil; hold on for dear life to good. Be good friends who love deeply; practice playing second fiddle. Don’t quit in hard times; pray all the harder.
Bless your enemies; no cursing under your breath. Laugh with your happy friends when they are happy; share tears when they are 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.’
Our Scriptures tell us that if you see your enemy hungry, go buy that person lunch, or if he’s thirsty, get him a drink. Your generosity will surprise him with goodness. Don’t let evil get the best of you; get the best of evil by doing good.”
