That Jesus was and is the Son of God is the underlying theme in the Gospel of St John. In turn, Jesus calls us to one-ness with each other and with God.
Jesus makes God known by the perfect love he shows for his fragile disciples. The disciples are to be recognised as sent by Jesus by the love they have for one another.
There are over 300 references to love in the New Testament. Love is God’s greatest gift to us. By our mutual love we reveal God’s love to the world. Pagans said to one another: in the time of the Early Church: ‘See how these Christians love one another!’ They were impressed by this mystery and at least some came to believe in Jesus.
