I just started Ancient-Future Worship by the late Robert Webber. 

So far I am really captivated by Webber's fresh approach of worship as "doing God's story."  He states that biblical worship "remembers God's work in the past, anticipates God's rule over all creation, and actualizes both past and future in the present to transform persons, communities, and the world. 

I have heard Webber in conferences in the past and have always been interested in the whole "ancient-future" theme.  This month, as part of my D. Min. course work, I am taking a class on worship called "Worship in the 21st Century" wherein we will focus on this book. 

Grace and peace to you, Pastor Bob Lee
