Love is an action of serving others. Jesus would’ve said in John 13 that He “loved His own who were in the world” to the end. Throughout the chapter, He demonstrates in practical terms what that love means.
If we are to love others and obey the commandment of our Lord, we are to serve one another. We must lay down the garments of our own pride and of our own comfort, and we must pick up the towel of humility and service, looking for opportunities to actuate the call of our Lord to love (read “serve”) one another.
