National spiritual revival can happen when as little as just one person takes the gospel seriously enough to take upon themselves the responsibility for the salvation of their whole nation, or even the world. It will require sacrifice, sometimes sacrifice of something we don’t even have available to give in the first place. The reason the world lies in pagan, evil, Christ-rejecting filth and confusion today is because there are few if any Christians remaining who possess the unique calibre of sacrificial enterprise that was demonstrated by Hannah, the mother of Samuel. We don’t need an army of Spurgeons. We need an army of Hannahs.
