Really great.
Plummer, a prof at SBTS, has written a concise, clear, and helpful book on various questions regarding the Bible. He manages to handle many questions without it seeming too "partisan", that is, he manages to explore how the church across the ages have approached interpretation (i.e. Origen and early church fathers allegorizing Jesus' parables). I will be recommending as a resource to accompany Bible reading and specifically the "how" of reading the Bible. I benefited greatly.
If you go to the Stone, you can purchase this book with the other books at the Get Trained table. Worth it even to have as a resource regarding highfalutin theological terms (e.g. Theological Interpretation of Scripture, Intertexuality, Source Criticism, etc.) Highly recommended.
