In his commentary on Revelation 7:9, David Chilton quotes Spurgeon’s exhortation to a gathering of missionaries with these words on whether there are many or few that will finally know God’s great salvation.
“I myself believe that King Jesus will reign, and the idols be utterly abolished; but I expect the same power which turned the world upside down once will still continue to do it. The Holy Ghost would never suffer the imputation to rest upon His holy name that He was not able to convert the world.”
