Check out this quote from Brian Edwards book, Revival!
"Men whom God uses in revival have always been men who maintained a close walk with God and longed for a holy life. It was Robert Murray M'Cheyne who, so greatly used by God in Dundee in 1839, had prayed from his heart, 'Lord make me as holy as a saved sinner can be.' The evidence of the sincerity in this prayer is seen in the fact that people would be moved to tears just by seeing him in the pulpit or walking down the corridor of the church."
It is just like the song that goes "Holiness, holiness is what I long for; holiness is what I need!"
It is what we all need.
