Charles Finney's ministry rolled like a spiritual shock wave across the American landscape in the nineteenth century. He attributed his effectiveness in large part to prayer. Now his superb insights are condensed and collected into a single book and and presented in a devotional framework. This book provides a 40-day devotional study for people desiring to pray with power and see results. Each daily reading-through meditations, application, and prayer--will help readers grow to Chirstian maturity.
