If the Holy Bible is the word of "God" then why has mankind changed these words throughout history? Is this because Mankind is more powerful than "God"? Or..... is it because "God" is a figment of imagination from Mankind?
I personally believe that my Holy Book - "The Lord of the Rings" is more powerful than your Holy Book because mine has Dragons!
Case settled Your Honor!
The Bible hasn't changed. It has merely been translated. If you check the Dead Sea Scrolls, you will find that the Book of Isaiah is almost exactly the same as it is today. The few differences don't change the meaning. The major differences are the differences in the shape of the ancient Hebrew language letters. That's around 2,400 years without change. There is no reason to believe that the rest of the Old Testament hasn't been translated similarly faithfully.
As for the New Testament, by the time of the Council of Nicea in 325 A.D., many writings that were blatantly opposed to the truth were floating around. The Council of Nicea took into account the documents that were true to the Old Testament, as well as those that were faithful to what the writings of Jesus' closest apostles had been. These they incorporated into what we know as the New Testament, while throwing out the others. We are blessed that we have the truth.
There are many other writings that have the truth in them. But they also have words that we don't know to be factual or truthful. In addition, the idea is to show people the way to eternal life.
How many more times would you like the truth to be spoken as part of a basic, foundational document? Getting the clear truth out of the Bible is at times difficult enough as it is. Why add a whole bunch of additional truthful documents to the thing? The whole idea is to save people for eternal life. Give them what they need... the Bible as it is.
How can something be "almost exact"? It is either exact or not.... there is no "almost". However, as you have stated that it has not been translated correctly then the book is no more truthful than a Dr Seuss book. His are just more entertaining.
Also, if the "Holy Bible" is the truth and you yourself follow the teachings of this book, I would assume you follow each and every direction to the letter. Assuming this to be true, then as your book states:
Luke 14:26 – " If anyone comes to me and does not hate his father and mother, his wife and children, his brothers and sisters—yes, even his own life—he cannot be my disciple." I feel for you that you hate your parents and are spending all of your time hating yourself. If this is the path you have chosen to accept your eternal life, have fun buddy. Whilst you do that I shall enjoy my time doing what I chose to do as my own free will allows.
