The New Testament is the second part of the Christian Bible, consisting of 27 books. It includes the teachings of Jesus Christ, the life of his disciples, and the early Christian church. Key texts are the four Gospels—Matthew, Mark, Luke, and John—which narrate the life and teachings of Jesus. In addition to the Gospels, the New Testament contains letters, known as epistles, written by apostles like Paul to various Christian communities. These letters provide guidance on faith and moral living. The New Testament concludes with the book of Revelation, which discusses prophetic visions and the end times.
