First published 20 years ago, this book is viewed by many as a classic. Peterson uses the Songs of Ascent (Psalms 120-134), a cycle of songs sung by Jewish pilgrims on their way to Jerusalem to worship, as a wonderful parallel to the modern (and timeless) Christian pilgrimage. Each chapter is a meditation on one of the songs, and Peterson draws out the ways each of them shows us an aspect of the Christian faith (repentance, providence, worship) and how they relate to each other. He highlights discipleship basics like worship, service, joy, humility, community, happiness and blessing, offering encouragement for growing in Christian belief and practice. May be difficult for a new believer to understand, but works well for group discussion for those who are more mature.
