As Jesus was having His last conversation with His disciples before His crucifixion, He gave them a new command for living. We read this in John 13:34-35. The new command was to love each other, just as Christ loves us. It’s important to note Jesus said this command was a hallmark of being His disciple. People will recognize we follow Jesus by the love we display for others.
Unless we love those around us, we will never be a disciple of Christ. God’s very nature is love, so if we want to look and live like Jesus, we must love people. Without love, we’re just making noise (1 Corinthians 13:1). Unless we love, we will never make a difference in this world.
