Why should I believe the Bible to be true? Why should I believe God is who in fact you interpret him to be? How do I know that you are not just poorly guided through false interpretation and or interpretation at all?
How am I to know that the book you hold in your hands was correctly translated from ancient Greek and Hebrew? After all, we know the English language did not provide an agreed upon form of spelling until the 1800's.
we also know that the same word used in a language can be used for multiple definitions. Their, They're, and There is a great example... one declares ownership, the other declares a conjunction, and the last a location. If we did not have an agreed upon form of spelling what is to say that the author may not have meant, "Their", transgressions; Instead He meant to declare a group as being the transgressors, "They're transgressors."
Without a proper form of spelling, we could indicate that grammar may have played a huge roll in translating the bible since 1611 when the first rendition of the King James was printed. There have been seven renditions since then if my memory serves me correctly.
We could go back even further prior to Martin Luther posting his own declaration upon the doors of the catholic church in 1500. Lets go back to the days just before then. To a time when the Catholic religion controlled much of Europe and was the law of the land.
It was common belief that if you were to read the bible without being a man of the cloth you would go insane! Let us also not forget that reading was not a common trait among people in those times.
In long story short. I was once in your steps. Attempting to share "Gods" word with the masses. Religion for the most part has been a root source in developing cultures. Honestly looking through history it appears as more of an early form of control. However its so developed and passed on that it can envelope a person easily when there are others who will validate an in factual basis. It aids in comfort to reasoning.
The question has to be in the validity of the book in which you repeat your claims from. Validity must be determined before you can even determine if God may or may not exist at all. If there is no Bible, there is no God.
Food for thought. Don't eat to fast or you'll get a stomach ache.
