At the end of 1 Corinthians 13, Paul identifies 3 things which should be a part of our lives: faith, hope, and love. These attitudes/actions/characteristics form the core of a fulfilled life, and even more importantly, a life that is pleasing to God. Paul concludes the chapter by saying, “but the greatest of these is love.” In context it is easy to understand that what he means, is that we should show love in all our interactions, not just toward the people we like or the ones we know. EVERYBODY!
