For those sojourners in this life who are seeking after higher realms of truth, this book is for you. Although he lived centuries before our time, John Bunyan went through fiery trials perhaps more difficult than many of us ever had, or ever will, in our lifetimes. If you ever feel alone in the world and without a friend, be encouraged in the reading of this book. The bottom line: Jesus Christ cares and truly rewards all those who seek Him diligently, no matter how dark the trials may seem at the time. This book is not for the faint-hearted.
