I'll answer your question if you first answer mine? Where exactly in the New Testament does it predict an end-time worldwide revival.
Until the Pentecostal movement swept the world India was practically closed to the gospel Africa was still regarded as the dark continent, the Latinos were locked in Catholicism and China remained impenetrable.
Suddenly we have this reverse situation where the western churches have become cold but MILLIONS are being swept into the church on these continents.
Did you know that Kenyans, Ghanaans, Ugandans etc are sending missionaries to Britain ... that is not a kid, that is happening. And what God is doing in China is entirely along Pentecostal lines.
