The Bible has been translated, re-translated and paraphrased more than any other book in history. Its subject matter includes hundreds of controversial topics, yet the Bible speaks with a harmony and continuity from Genesis to Revelation.
The Bible has been read by more people and published in more languages than any other book in history. It is divided into two parts: the Old Testament and the New Testament. Some have observed, on the one hand, that the Old Testament foreshadows the New, while on the other hand, the New Testament fulfills the Old Testament. In other words the New Testament is concealed in the Old, while the Old Testament is revealed in the New.
The Old Testament predicts the coming of a person, a promised Messiah or Savior, while the New Testament presents that person. The person presented is the Lord Jesus Christ, who in his birth, life, death and resurrection fully validates both the Old and New Testaments.
You can investigate the validity of these claims by diving into any Cornerstone Bible Study, but a good place to begin is with God’s Unique Book: The Bible.
