The Principium Institute has just published my new booklet on prayer, entitled, Speaking with God: A Short Primer on Mental Prayer. It is available both electronically from Kindle, as well as in paperback. I hope you find it to be a helpful little resource on how to get more out of prayer. The Principium Institute will be publishing more helpful resources like this one, from me and from a number of other scholars who are trying to write works that are accessible and helpful for ordinary Christians beyond the small circle of scholars for whom we often write. Right now the Kindle version of my text is selling for only 99 cents, and the 65 page paperback sells for $3.99.
