The true Bible is the one that will give you joy and happiness; even it is all just composed of stories.
Like this one:
We know enough about the changes that have taken place in the Bible canon to find and remove them so that they agree with the earliest and most accurate manuscripts. The Dead Sea Scrolls and the Septuagint versions of the Hebrew Scriptures, the first 39 books of the Bible, for example, reveal that the words in the Hebrew Scriptures have barely changed.
In the Greek Scriptures, the historical record indicates that Matthew wrote his gospel first, in 41 CE about 8 years after Jesus' death and resurrection. The last books, consisting of the gospel of John, Revelation, and the three letters of John, were completed before the end of the first century.
As they were written, an early version of the book, called the codex, was invented, and history reveals that the Christians used this form extensively in their preaching all over the world of that time.
Those Christians knew what was authentic, and what wasn't, and many of the apocryphal books of the Christian Greek Scriptures were not written and circulated until after the first century, after the apostles died.
It is NOT true that the collection of the Christian scriptures had to wait until the fourth century, when the Emperors Diocletian, Constantine, and Theodosius imposed their version of Christianity on the Roman Empire. The Christians of the first century knew what was inspired and what was not, and they used their scriptures in their ministry.
There have been some additions that have been identified in the Christian Greek Scriptures. Among them are Mark 16, from verse 9 to the end of the chapter, which said that Christians would hold snakes and drink poison, and 1 John 5:7, a verse called the Johan nine Comma, which attempted to put the trinity into the scriptures several centuries after John had died.
But most of the scriptures are what was written under God's inspiration, and we can put our trust in them for our instruction and salvation.
