Why do you think God chose the Jews for the Messiah of all mankind? Why not the Chinese, or any of the other ancient cultures that were around at the time? You take it for granted, just as many others do. No, it was planned from the start. The Messiah and the Bible are one.
If by "Messiah and the Bible are one" you mean that God chose Abraham and his specific seed ( Issac, Jacob ...... Judah.... to bring us Jesus - then I would agree. On the other hand, if you believe that Jews because they are Jews somehow are automatically received and accepted into God's kingdom and heaven - you are wrong.
Judaism will not save you! The OT will not save you! The law of Moses will not save you! Being born a Jew will not save you! Living a virtuous life will not save you! Jewish tradition will not save you! The Talmud will not save you!
There is coming a day when all Israel will be saved. In that day, all of Israel (all Jews) will accept Jesus as their Messiah. Unfortunately, that day has not yet come.
The following from gotquestions.org pretty much summarizes what I've been trying to say:
Question: "Are Jews saved because they are God's chosen people? Will Jews go to Heaven even if they do not trust in Jesus?"
Answer: The Jews are God’s chosen people, according to Deuteronomy 7:6, but that does not automatically make all Jews saved. Jesus said, “I am the way and the truth and the life. No one comes to the Father except through me” (John 14:6). That “no one” includes Jews and Gentiles. For a Jew to be saved, he or she must come to God the Father through faith in Jesus the Messiah.
John the Baptist warned his Jewish audience against trusting that their lineage made them right with God: “Produce fruit in keeping with repentance. And do not begin to say to yourselves, ‘We have Abraham as our father.’ For I tell you that out of these stones God can raise up children for Abraham” (Luke 3:8).
No matter who we are, we must repent (see Luke 13:5). Physical ancestors do not guarantee a spiritual conversion. Even Nicodemus, a ruler of the Jews, had to be born again, or he would never see the kingdom of God (John 3:1–8).
