At this very moment, millions of professing Christians are joining with millions of other "believers" to promote peace and reconciliation across the country and around the globe. These pragmatic, purpose-driven churches and organizations are uniting for the ecumenical "common good" to eliminate poverty, eradicate disease, and save the earth from political and environmental disaster -- all in the name of advancing "God's kingdom on earth." But are all of these good works derived from a biblical blueprint for humanity? Or are these well-meaning workers building a house on foundations of sand? You may very well find your church inside the pages of this book.
