And He said unto them, These are the words which I spake unto you while I was yet with you, that all things must be fulfilled, which were written in the law of Moses, and in the prophets, and in the psalms concerning me. (Luke 24:44)

With this introduction, Jesus continued and . . .

. . . opened He their understanding that they might understand the scriptures. (Luke 24:45)

What was the key Jesus gave them to understanding the Scriptures? The fact that its major theme focused on Him:

. . . Thus it is written, and thus it behooved Christ to suffer, and to rise from the dead the third day:

And that repentance and remission of sins should be preached in His name among all nations, beginning at Jerusalem. And Ye are witnesses of these things. (Luke 24:46-48)

The Old and New Testaments both tell the story of Jesus. The Old Testament prepares us for its happening and the New Testament tells how it happened. This unites the Bible in one major theme. The people who looked forward to Jesus under the Old Testament were saved from their sins through faith in God's promise. Everyone who looks back to it as having been fulfilled in Jesus Christ is saved in the same way: Through faith that it happened just as God promised.

DIVERSITY OF THE BIBLE

When we speak of the "diversity" of the Bible we mean that the Bible has variety. It records different ways in which God dealt with people and the different ways in which they responded to Him.

The Bible is written in different moods. Some portions express joy while others reflect sorrow. The Bible includes different types of writing. It contains history, poetry, prophecy, letters, adventure, parables, miracles, and love stories. Because of its variety, the Bible has been further divided into major groups of books.
