I hope this book of prayers will inspire everyone who reads it. I hope you apply its principles to life's trials. Victory is yours; because prayer changes things. That's the key. Prophetess Mary Dickerson moved to Las Vegas when she was a teenager. She is the mother of seven children, and grandmother of five. She is also the author of "Calling all Angels" which was published in 2006. The prophetess has been working for Jesus since she was called to the ministry over twenty years ago. Living in a city that the world says; "never sleeps," she has raised her children there, and prayer made it all possible.
