'What do you think was meant to characterize authentic human living? What was the original (and still unchanged) purpose of human existence? That our lives might revolve around service to God and love of others. In practical, tangible ways, my life ought to demonstrate devotion to God and a self-sacrificing love of others. If it is not, I am living neither in authentic Christianity nor in true humanity. True spirituality is inseperable from the stuff of daily life, and inseperable from true humanity. I am never more authentically human than when I am living in functional worship of God and active love for my neighbor.'
Paul David Tripp, Broken-Down House, p.90.
