Is it reasonable to believe that God hears prayer, and more importantly, that God genuinely responds to prayer? And what kinds of prayers should we be praying in order to see an almighty God move with power in our lives and churches? In this sermon Steve Johnstone addresses these important and yet difficult issues.
