"Christians see in the New Testament the fulfillment of the promise of the Old Testament. It relates and interprets the new covenant, represented in the life and death of Jesus, between God and the followers of the Christ. Like the Old Testament, it contains a variety of kinds of writing. Among its 27 books are selected recollections of the life and acts and sayings of Jesus in the four Gospels; a historical narrative of the first years of the Christian church in the Acts of the Apostles; the Epistles—letters of advice, instruction, admonition, and exhortation to local groups of Christians—14 attributed to Paul, one (Hebrews) probably in error, and seven by three other authors; and an apocalyptic description of the intervention of God in history, the Book of Revelation."
