Query: Machen's Book is Still the Standard

The long ago departed J. Gresham Machen provided the academic world with the standard text for teaching Koine (common) Greek, often called New Testament Greek. This book is extremely well done, and after viewing two three separate Greek texts, this is the most detailed. He covers all the rules in Greek such as declensions, Present Actives, Participles, aorists, imperfects, Perfect tenses, subjunctives, etc. His vocabulary section in the back is great for the student as a quick reference or study tool for memorization. Further, as another reviewer noted, one can practice what they have learned in each chapter with Greek to English and English to Greek exercises. This is more difficult book than Mounce's text if one was trying to learn Greek alone. With a minor in Greek, I suggests one seek a teacher or someone with at least two years of Greek if using a book to learn Greek anyway.
