Excellent book on Prayer

Hi all,
Just found this book and it blessed me - the Top 7 Prayer classics. See: http://christianclassicbooks.blogspot.com/p/featured.html

If you want to grow in prayer, strengthen your faith and be challenged by men and women of God who were mighty in prayer, I'd recommend it.

It's an eBook and includes the full text of:
• How To Pray – by R. A. Torrey
• With Christ in the School of Prayer – by Andrew Murray
• Prevailing Prayer – by D. L. Moody
• How I Know God Answers Prayer – by Rosalind Goforth
• Answers to Prayer – from George Muller’s Narratives
• Power Through Prayer – by E. M. Bounds
• A Short and Easy Method of Prayer – by Madame Jeanne Guyon
