This month’s free audiobook from Christian Audio is R.A. Torrey’s ‘How to Pray’. It will only be available in February, although you can get a free e-book from CCEL.
Christian Audio summarise How to Pray as follows:
How to Pray is a gripping call to prayer read in an enlivening style. Pastor, educator, evangelist, and author R.A. Torrey delivers a no-nonsense handbook for praying correctly and receiving answers from God. The book is full of examples, stories, and anecdotes that inwardly compel the listener to pray heartily. Topics covered include the importance of prayer, praying in the Spirit, constancy in prayer, and hindrances to prayer.
