Which one? Honey, at the end of the day, there is only one. Oh, yeah...I know that there are many, many different versions...but they all pertain to the same book...or, more properly, set of books.
As someone else pointed out, these books were not written in English, but in ancient languages...namely, Greek and Hebrew. Even if we had an original, intact manuscript, every day folks like you and I would not be able to read the thing...we would still have to depend on translators to tell us what it says.
As it is, what we have are very old, deteriorating copies of copies of copies of the originals. They mainly lie in museums, kept in a specialized environment to prevent further deterioration, and are handled only by people who know what they are doing.
Here's the thing...we have faith that, through all this copying, and translating, and everything that the scrolls have suffered since they were first penned, that God has preserved for us the important information...what we need to know to attain His most precious gift...eternal life.
At the end of the day, it doesn't really matter what version you read.
What matters is...will you repent, and come to Jesus Christ?
God is not willing that you should perish...why would you choose to die??
