From the Foreword -

This little book invites us to study with some ancient experts in prayer, the persons who wrote the Book of Psalms. We haven't read long in the psalms before we realize that the authors were altogether human, with a massive catalog of troubles, inconsistencies, and questions. Their lives were marked by breathtaking highs and lows, with sometimes only a few paragraphs between. But with all of that, they were saints. They left us with the greatest collection of prayers in the possession of our human race.
What was their secret? I believe it was the quality of their friendship with God. And of course the language of that friendship is prayer. The psalmists don't give us any formula for effective praying. They don't offer a set of rules. But if we read their prayers carefully, we will learn something of their secret, the secret of the Ultimate Friendship. I hope through this book to start us on that special journey.
