What is the difference between the Old and New Testaments?
The Old Testament tells God’s dealings with Israel and the world from creation through prophets; the New Testament tells the coming of Jesus and the formation of the church. One book, two acts, one Christ.
The Old Testament — 39 books — covers creation, the patriarchs, Israel, the law, the kingdom, exile, and the prophets. It tells the story leading up to the Messiah.
The New Testament — 27 books — opens with Jesus’ life, death, and resurrection, then the birth and growth of the church, and looks forward to his return.
They are not two different Gods or two different books. Jesus said the Scriptures "testify about me." The Old Testament longs; the New Testament arrives; both center on Christ.
