For a refresher course, and a brief summary, here’s Romans 12:10-13:
10. Be kindly affectioned one to another with brotherly love; in honor preferring one another;
11. Not slothful in business; fervent in spirit; serving the Lord;
12. Rejoicing in hope; patient in tribulation; continuing instant in prayer;
13. Distributing to the necessity of saints; given to hospitality.
