We are one kingdom family, brothers (Romans14.13,15,21), and 'God's love has been poured into our hearts through the Holy Spirit' (5.5). The hallmark, the characteristic family trait we all share, must, therefore, be expression of this love. We are to 'love one another with brotherly affection' (12.10), and to 'owe no one anything, except to love each other' (13.8).
