Book excerpt: God—The World’s Future has been a proven textbook in systematic theology for over twenty years. Thoroughly revised and expanded, this third edition is explicitly crafted to address our postmodern context and explains the whole body of Christian historical doctrine from within a “proleptic” framework. Peters skillfully deploys this concept not only to organize the various theological areas or loci but also to rethink doctrines in light of key postmodern challenges from ecumenism, critical historical thinking, contemporary science, and gender and sexuality issues.
