Revival is not defined by God deciding to show up. Revival is defined by us deciding to pay attention and live by what has always been right, good, pure and true.
Humanity has a tendency to only cry out to God when we are desperate or scared. In his mercy, he always responds with grace, though we deserve the grave.
If we will fall on our faces, repent and purify our hearts, he will redeem and restore. I know it because history proves it. He has always come quickly to those who seek him.
