From Beg God to Move Again:

History shows us that there is no exact prescription for revival. It is an act of the sovereign God, and we can’t dictate what he should do and when he should do it. I have been praying for revival in Sri Lanka since 1975. Only once, while attending a conference, have I seen something close to revival. But I continue to pray that, in my lifetime or after, the Lord would send his showers of blessing upon our people through revival.
