Why is love among Christians essential?

In John 13:34-35, Jesus commands His followers to love one another, declaring that it is through our love for each other that the world will know we are His disciples. This love is not conditional or based on mutual benefit, but is a sacrificial, selfless commitment to seek the wellbeing of others. In Peter's exhortation to be of one mind and to love one another, he underscores that our unity in Christ is made manifest through love. This love acts as a binding force in the church, drawing individuals together and displaying the transformative power of the gospel.
