Jesus as Promised Messiah is found pretty much in all of the canonized books, and the scriptures contain the gospel message, and they alone are the very words of God that can save lost sinners
The words do not save (the gospel message is not an incantation).
But yes, the Bibke does contain the gospel, history about Israel as a nation, information about Jesus, and doctrines about the Christian life, and information about Jesus.
My point is that you were wrong. The list does not have to read the Bible in order to be enabled to be saved and then hear the gospel message to be saved.
I asked you where you got that idea, but you have not answered.
Before the New Testament was compiled Gentiles were saved by others telling them the gospel message. Paul met these people.
Likewise, God saves men today through the gospel message - whether explained to them by another person or read in the Bible.
