In this book, East aims to lay out the foundations of the Christian faith throughout 93 letters. While certainly not exhaustive, he makes them clear and accessible to anyone willing to pick up this book and read it.
His goal throughout the letters is not to represent one denomination, but rather the one faith of Christ's body that would be recognizable by both the Christian today and the Christian who lived 1500 years ago.
This book challenges the reader to think about what Scripture has to say about creation, mankind, sin, death, Israel, the gospel, and the end times (to name a few). The letters take us throughout the whole realm of Scripture while also tying in various aspects of poetry, theology, and church history.
While most will not agree with every single one of East's beliefs, every Christian will delight in where he lays his foundation and hope throughout this book - the One who is at the center of the faith, Jesus Christ.
