In this book Rob frequently speaks about the necessity and urgency for prayer. Not the prayer that is inserted into a church service out of obligation, but travailing prayer. We travail when God lays a heavy burden for a soul or souls or even a city or nation upon our heart that causes intense spiritual pain and we agonise and cry out to God continually for His Spirit to cause their turning. Do you have a burden to see revival in your town, city or nation, have your tears soaked your carpet? Then this book is for you.
