Revival is needed whenever the love of God’s people has grown cold, we read in Revelation 3:15-17
I know all the things you do, that you are neither hot nor cold. I wish that you were one or the other!, But since you are like lukewarm water, neither hot nor cold, I will spit you out of my mouth!, You say, ‘I am rich. I have everything I want. I don’t need a thing!’ And you don’t realize that you are wretched and miserable and poor and blind and naked.
