'There is no literature in all the world that is more true to life and more honest than Psalms, for here we have warts-and-all religion. Every skeptical thought, every disappointing venture, every pain, every despair that we can face is lived through and integrated into a personal, saving relationship with God - a relationship that also has in it acts of praise, blessing, peace, security, trust, and love.
Good poetry survives not when it is pretty or beautiful or nice but when it is true: accurate and honest. The psalms are great poetry and have lasted not because they appeal to our fantasies and our wishes but because they are confirmed in the intensities of honest and hazardous living.'
Eugene H Peterson, A Long Obedience in the Same Direction, p.69.
