Worshipping Trinity [PDF ebook] 
Coming Back to the Heart of Worship (2nd Edition)

If worship is God centered, and God is the Trinity, then worship should be Trinity centered. ‘Worshipping Trinity’ explores the meaning and implications of that simple claim. Written for church leaders, worship leaders, and songwriters, as well as for those interested in theology, this volume explains why the Trinity matters so much and explores practical ways our worship can be made more Trinitarian. This second edition is fully updated and expanded.
