Why is it important to love one another as Christians?

The call to love one another is rooted in the very character of God, who is love (1 John 4:8). When we love one another, we embody the essence of our faith, which is to reflect Christ's love toward us. As seen in John 13:34-35, Jesus commands us to love others as He has loved us, indicating that our love for one another is a testimony to the world of our discipleship. This love is not merely an emotional response but is enabled by the Holy Spirit, affirming our standing in the light and showcasing the transformation that occurs in the life of the believer.
