@Trailblazer is correct in what she offers to you, though many others will not say it Trailblazer does.
The Bible is a closed book, in both the Old and New Testament you will see passages that indicate the meanings are locked and hidden until an age would come when the Books are open and the Keys given.
Daniel 12:4 "But you, Daniel, shut up the words and seal the book, until the time of the end. Many shall run to and fro, and knowledge shall increase.”
It was closed since the Message Jesus gave
Revelation 5:2 "And I saw a mighty angel proclaiming in a loud voice, “Who is worthy to break the seals and open the scroll?”
Revelation 5:4 "I wept and wept because no one was found who was worthy to open the scroll or look inside.."
I can quote many passages, but basically Baha'u'llah gave the keys ro understand all the past Holy Books, if one immerses themselves in those keys, then when we read passages of the older books, they take on new meaning, they are seen in a new light, just as the Christians will see with the writings in the Tanakh.
The old is made New, just as promised in the Bible.
