Absolutely excellent! Thorough, in depth, easy understand and jam packed. Wonderful tool for the layman, student and pastor. Every level of expertise including beginner through seminary professor will find this set of books a helpful tool. The writing style is embracing and welcoming. Not stuffy or boring. Stirs up an inner craving to learn and research more. A wonderful set of books. You won't be disappointed. (Former seminary student and college professor.) This is my second set. Gave a set away. Transports the Bible right into your living room.
