A few years ago a Kickstarter project raised over a million dollars to produce a multi-volume Bible with high-quality design and no chapter or verse numbers—a true reader's Bible. Since then, the major Bible publishers have been in a rush to produce similar Bibles in both single-volume and multi-volume sets. I recently got the NIV Reader's Bible, a beautiful all-in-one Bible, and I was impressed. Then I got the four-volume NIV Sola Scriptura Bible and was blown away.
The NIV Sola Scriptura Bible (henceforth NSSB) is the highest-quality Bible I've ever owned. It's cloth over board, but the covers are more solid than other cloth-over-board Bibles I own (NIV Reader's Bible, the ESV Reader's Bible, and the Bibliotheca New Testament). Each of the four volumes has a brief introduction explaining both the NSSB and the volume itself: why the books are arranged the way they are, and what the significance of those books is.
Only Volume I: The Torah and Former Prophets (Genesis–Kings), follows the book order of our modern Bibles. The three Old Testament volumes follow the Hebrew major divisions (Law, Prophets, Writings), but the individual books follow a different, though understandable order. The New Testament has the most novel arrangement. It is divided into four sections headed by each of the gospels and followed by other books associated with each gospel either by relation (Paul to Luke, Peter to Mark, the writings of John), or theme (Matthew, Hebrews, and James are more distinctively Jewish). Because the NSSB is focused on enhancing the reading experience by removing distractions, there's no need to follow the traditional order of books. Reading a more chronological or thematic order may help produce insights you might otherwise miss if reading through in the traditional order.
The NSSB's best qualities are the strong, durable design and thick, white paper providing a strong contract between the page and the black ink of the biblical text. Other reader's Bibles may have larger margins (Bibliotheca), slightly larger spacing between lines (Bibliotheca and NIV Reader's Bible), or a marginally larger font (10.3 compared to 10.5 in the NIV Reader's Bible), but the overall quality of the NSSB is hard to beat. I've yet to get my hands on the 6-volume ESV Reader's Bible, but for anyone looking for a multi-volume, easy-to-read Bible, the NSSB is a great set to bring home.
