The Bible is made up of 66 books written by approximately 40 authors over a span of roughly 1,500 years. From Genesis to Revelation, each book has its own voice, genre, and purpose — yet together they tell one unified story of God's relationship with humanity.
Most Christians can rattle off a handful of their favorites — Psalms, John, Romans — but how many can name all 66? More importantly, how many know which books belong to which category, and why each one matters?
This guide walks you through all 66 books organized by testament and category. By the time you're done reading, you'll have a much clearer picture of how the Bible is structured — and you'll be ready to put your knowledge to the test with our daily BookFix puzzle.
The Old Testament — 39 Books
The Old Testament was written primarily in Hebrew (with small portions in Aramaic) over more than a thousand years. It covers the creation of the world, the history of the nation of Israel, poetry and wisdom literature, and the writings of the prophets.
The Law (Torah) — 5 Books
Also called the Pentateuch, these five books were traditionally authored by Moses. They cover creation, the fall of humanity, the lives of the patriarchs, the Exodus from Egypt, and the laws God gave to Israel.
History — 12 Books
These books trace Israel's history from entering the Promised Land through the conquest, the period of the judges, the united and divided kingdoms, and finally the exile and return.
Poetry and Wisdom — 5 Books
These books explore the deepest questions of human experience — suffering, praise, wisdom, love, and the meaning of life. They remain among the most beloved books in all of scripture.
Major Prophets — 5 Books
These five books are called "major" not because they are more important, but because they are longer. They contain some of the most detailed prophecies in the Old Testament — many of which point directly to Jesus Christ.
Minor Prophets — 12 Books
The twelve minor prophets are shorter books but no less powerful. They call Israel back to faithfulness, warn of coming judgment, and point toward the coming of the Messiah.
The New Testament — 27 Books
The New Testament was written in Greek in the first century AD. It records the life, death, and resurrection of Jesus Christ, the birth and growth of the early church, and letters of instruction to believers.
The Gospels — 4 Books
The four Gospels each tell the story of Jesus from a different perspective — Matthew for a Jewish audience, Mark for urgency and action, Luke with detail and compassion, and John with theological depth.
History — 1 Book
Acts — written by Luke as a sequel to his Gospel, Acts traces the spread of the gospel from Jerusalem to Rome through the work of the Holy Spirit and the apostles, especially Paul.
Paul's Letters — 13 Books
Paul wrote 13 of the 27 New Testament books — letters to churches and individuals that form the theological backbone of Christian doctrine.
General Epistles — 8 Books
Prophecy — 1 Book
Revelation — written by the apostle John while exiled on the island of Patmos, Revelation contains visions of the end times, the return of Christ, and the ultimate triumph of God over evil.
