Hans Boersma’s Heavenly Participation: The Weaving of a Sacramental Tapestry is a plea for Christians to honour the presence of God in all things. Boersma begins with a critique of a modern tendency to erect far too firm a wall between nature and God. Many modern Western Christians, he suggests, have unknowingly allowed this dualism to shape their views of time, nature, the human person, and even Scripture. The cure? A rediscovery of the “sacramental worldview” espoused by Augustine, Irenaeus, and C.S. Lewis alike. From this perspective, “The entire cosmos is meant to serve as a sacrament: a material gift from God in and through which we enter into the joy of his heavenly presence."
