Penned in 1900, Torrey's timeless classic has guided generations of new (and seasoned) believers into a richer, more effective prayer life. With chapters like "The Importance of Prayer," "Obeying and Praying," "Abiding in Christ," and "When to Pray," it provides Scripture-based lessons on maintaining a devotional and worshipful lifestyle. Updated for the modern reader, words, expressions, and sentence structure have been revised for clarity and readability.
