Like most collections of essays, this book is mixed in quality. S. Lewis Johnson's treatment of Galatians 6:16 was careful and thorough. It was the best treatment of that passage that I've read.
Hoehner's chapter briefly but carefully covers debated issues related to the Last Supper in the Gospels.
Elliot Johnson's article on interpreting apocalyptic texts helpfully orients the reader to the issues and offered some cautions.
Merrill's article on Daniel's contribution to the kingdom theme was more insightful about the importance of the kingdom theme in general than it was on Daniel's specific contribution.
John Martin was able to demonstrate that there is no one dispensational interpretation of the Sermon on the Mount.
In general, if this book can be picked up inexpensively, it is worth it for Johnson's article.
These are a great collection of articles written from a dispensational point of view. I thought they were well-balanced and covered some very important and foundational theological issues.
