This book is the last work Dr. Gerstner prepared for publication before his death in 1996. It is a mini-systematic theology in question and answer format. Dr. Gerstner gives 25 chapters of theology where an unregenerate inquirer is dialoging with a regenerate Christian. These are tough questions about all aspects of Christian doctrine including the nature and existence of God, heaven, hell, apologetics, justification, Romanism, sanctification, angels, and miracles. Very readable and engaging; contains a foreword by R.C. Sproul.
