The Bible tells an overall story about the history of the world: creation, fall, redemption and God’s Last Judgement of the living and the dead.
The Old Testament (which dates to 300 BCE) begins with the creation of the world and of Adam and Eve, their disobedience to God and their expulsion from the garden of Eden.
The New Testament recounts the redemption of humanity brought about by the life, death and resurrection of Jesus. It finishes in the book of Revelation, with the end of history and God’s Last Judgement.
