Book excerpt: Prominent thinkers, writers, and well-known voices in the Episcopal Church come together to present a very broad spectrum of Christian thought and eschatology. Ultimately, what they have in common is the belief that the choice Christians must make is not between the now and the eternal; it is between being forward-looking and being back-ward looking. Unless we look with eagerness and longing toward the future, we will stay stranded in the past. To live the Christian life today, we need a heart for the future.
