Gospels
The first four books of the New Testament are the Gospels: Matthew, Mark, Luke and John. Each Gospel tells the life story of Jesus. The first three Gospels -- Matthew, Mark and Luke -- are similar in content and structure. Because of this, they are grouped and labeled the "Synoptic Gospels." Compared to the Synoptics, the book of John has markedly different subject material and organization.
Acts
The fifth book of the New Testament is Acts of the Apostles, or simply "Acts." Acts recounts the early history of Christianity. After the death and resurrection of Jesus Christ, the Twelve Apostles began to preach and minister in a variety of locations. Acts relates some of their stories and depicts the growth of the Christian religion. The second half of Acts focuses on Paul, an anti-Christian who later converts and becomes a missionary.
Paul's Epistles and Hebrews
Books 6 to 18 of the New Testament are letters, called "epistles," written by Paul. Paul's epistles are addressed to various communities and deal with philosophical and social issues facing new Christians. These 13 books are: Romans, 1 Corinthians, 2 Corinthians, Galatians, Ephesians, Philippians, Colossians, Thessalonians, 2 Thessalonians, 1 Timothy, 2 Timothy, Titus and Philemon. It is a matter of debate whether Paul is the writer in Hebrews.
General Epistles
The seven general epistles -- James, 1 Peter, 2 Peter, 1 John, 2 John, 3 John and Jude -- are ascribed to various authors and are addressed to a general Christian audience, rather than the specific communities addressed in Paul's Epistles. The General Epistles are alternatively called the "Catholic Epistles" and make up books 20 to 26 of the New Testament.
Revelation
The 27th and final book of the New Testament is called the Book of the Revelation to John, or more commonly, "Revelation." Revelation is unique in that it is the only New Testament book to focus entirely on prophetic experience. Its use of vibrant symbolism is also a distinguishing characteristic. Though a man named John is the attributed author, the writer's exact identity remains unclear.

All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, that the man of God may be competent, equipped for every good work.
