"A Long Obedience in the Same Direction" is a book by Eugene Peterson that explores the concept of spiritual growth and discipleship. Peterson emphasizes the importance of commitment and perseverance in the Christian faith, likening it to a journey that requires consistent effort and dedication over time. He draws on the Psalms of Ascents to illustrate how faith is not just a one-time decision but a lifelong process of following God. The book encourages readers to embrace the challenges and joys of this journey, highlighting that true transformation comes from sustained obedience. Peterson argues that in a culture focused on instant gratification, the value of a long-term commitment to faith is often overlooked, yet it is essential for deep spiritual maturity.
