Take a moment and think of the person you would consider your worst enemy. The person you hate (or at least strongly dislike) with every fiber of your being. Perhaps this is someone who has betrayed you in the past. Perhaps this is someone who gets on your nerves and pushes all your buttons. Perhaps this is someone who is meanspirited and rude or condescending and arrogant.
You got that person in your head? Good. Now imagine doing something really nice for them. Like REALLY nice. Like shoveling snow from their driveway in the middle of winter. Like buying them a fancy dinner from their favorite restaurant of all time. Like giving them a genuine compliment on their appearance or their work.
Could you do it? Could you actually sacrifice your time, effort, money, and/or pride to do a nice thing for someone who wouldn’t think twice about turning on you and throwing you under the bus? If most of us are being honest with ourselves, we wouldn’t go through with it. We wouldn’t want to waste our time and resources on someone who will never show us any kindness or respect in return.
Thankfully, Jesus is a lot more humble and loving than we naturally are.
