Book excerpt: How many ways can your church's worship equip the congregation for its mission? Worship changes through the seasons, from Christmas, through Lent and Easter, and beyond. The way worship relates to your church's mission should change, too. This book explores those seasonal changes by examining both worship and mission as aspects of union with Christ. Just as we are to follow Christ through the various stages of his life and work in worship during the church year, we can follow him in our mission through these same stages of his life and work.
