__ Leonard Ravenhill was a Christian evangelist who focused on prayer and revival. He is best known for challenging the modern church (through his books and sermons) to compare itself to the early Christian Church as chronicled in the Book of Acts. I personally believe what he preached is a uniquely continually relevant message that speaks to the eternal needs of the Church, specifically the Church of America.  Listen to these powerful messages below. (messages are 20yrs old so quality may be low)

-No Man is Greater Than His Prayer Life
-Desperate Prayer
-Weeping
-Take Time To Be Holy
-Revival
