John’s Gospel divides at a hinge point, after which the Spirit’s own description shifts in three identifiable ways. John 13 through 20 supplies the working pattern for Christian ministry that follows from that shift. The Spirit himself, the sermon argues, is what makes a believer’s life both already fulfilled and not yet complete at the same time.
A real Protestant Dark Ages gets named here, traced to the collapse of the older doctrine of man’s fourfold estate. Romans 8:28’s promise of ‘all things working together for good’ gets rescued from a popular misuse that reduces it to earthly blessings. The actual goal is glorification, this sermon insists: possessing God himself, whatever the earthly cost along the way.
