Search the scriptures; for in them ye think ye have eternal life: and they are they which testify of me. - John 5:39 KJV
Jesus is the central theme of the book.
From Genesis, where His first coming is announced as the solution for the problem of sin to Revelation, in which His return is announced, the person and work of Christ run through each page of the Bible.
Although is true that in the Bible we can find history, science, poetry, prophecy, literature, and so many other things, the central theme is Jesus and what He did to save humanity.
