How does the command to love one another reflect Christ's love?

In John 15:12, Jesus articulates, 'This is my commandment, that you love one another as I have loved you.' This command encapsulates the essence of Christian living, urging believers to emulate Christ’s sacrificial love. His love was demonstratively laid down in the act of the cross, illustrating the depths of commitment and care we ought to express toward one another. By loving others selflessly, we reflect the true nature of Christ's love and serve as a testimony to the world about our relationship with Him.
