But does that ancient practice still matter? Still deeply engrained in both the Christian and secular calendar, nonetheless, what Sunday is and why it matters is no longer clear. Why Sunday Matters explores the forgotten reasons why Sunday is essential to Christian life. It also uncovers some of the contemporary obstacles keeping people from living Sunday faithfully. From youth sports to our neglect of the poor to our addiction to technology, Why Sunday Matters takes a wide-ranging look at the importance of the Lord's Day and why it’s urgent we recover the Christian practice of Sunday.
