In the book, "God Tells the Man Who Cares", A.W. Tozer wrote that the church will actually transform the surrounding community as she prays and seeks to be uncontaminated by the world...
"By consecration, detachment, obedience and unceasing prayer we must escape the clutches of the world. Pure Christianity, instead of being shaped by its environment, actually stands in sharp opposition to it, and where the power of God has been present over a sustained period the church has sometimes reversed the direction of things and exercised a purifying effect upon society" (p. 45).
Historically, revival begins with God's people in the church, and then it moves out into the community. Revival is not needed if the church is actually being the church that God intended. Holiness and "unceasing prayer" will get us closer to what the Lord desires.
For Jesus Alone!
