I won a free copy of this book from Stephen nearly two years ago in a contest he did at his blog determining the ten greatest moments in sports history. Here's a description from the publisher:
Scripture calls Christians to do everything for the glory of God. That means every thought, every word, and every deed are to be done in a way that brings pleasure and honor to him. Believe it or not, this includes playing, watching, and talking sports! But most of us fail to recognize how sports fit into the big picture of a God-glorifying life, unable to imagine that the God who created the universe might actually care about Little League games and Monday Night Football.
So how do we play, watch, and talk sports for God's glory? Game Day for the Glory of God seeks to answer that question from a biblical perspective. Sports fan Stephen Altrogge aims to help readers enjoy sports as a gift from God and to see sports as a means of growing in godliness.
I think the book is ideal for junior high and high school athletes, but it is also an excellent book for fathers to take their younger children through, to help them get a grasp on how to engage in sports (either viewing or playing) in a God-exalting manner.
