We are commanded by Jesus to love each other. In fact, Jesus equates our loving each other with the fulfillment of all of His commandments.
Love is to be our life and the very fulfillment of all that God desires of us–all of His requirement for perfection is attained in this one verb–to love. In fact, we are never more like Jesus than we love each other with God’s divine agape love. Therefore, it is extremely important that we understand this word–agape–and what it means in all of its vast context so that we might love as we have been loved.
