I know a girl that used to claim that she was an agnostic (which means that she does not know if god does or does not exist) So I was a little suprised when the girl became short with me when I would speak of how JESUS is the CHRIST. At that point Is started to realize that a small number of people were actually ignorant that god exists, instead I feel that many people use ignorance as an excuse. What I mean is that christianity (following after the model of JESUS) is anti-selfishness, not all church-goers follow what is in the Bible. But if a person desires to follow after the teachings of JESUS that person is required to put there desires on the back shelf (by the way I like to think that I try to show others Love, but I must continuely deny my natural feelings.
The truth is that most non-christians say that they do not know (that there is a god) but the realiety is that most people do not want there to be a god, because that would mean that there is some sort of a code to live by. So I smile at the fact that you did some research about JESUS. (As a side note I want to tell you that The GOD of the Bible says that
-If you look for me wholeheartedly, you will find me.- (Jeremiah 29:13)
What I am worried about is the fact that 'we humans' have a decietfut and wicked heart so I am concerned that you will be decieved into thinking that you are diligently searching.
Its true that for thousands of years the Bible was not yet translated into English. The first partial translation into English would have been with Wiliam Tynsdale (not the King James) I have respect for Tynsdale because the man was driven with a passion that turned him into an outlaw https://christianhistoryinstitute.org/store/dvd/4737d/gods-outlaw-the-story-of-william-tyndale (I again smile because I have requested information about Tynsdale for christmas)
The Bible is completely flawless, but what is not flawless are the translations. The Bible was origionaly written in 3 languages (mainly two) It would be like saying that the first part of the U.S. constitution was written in the Hebrew language, and the second part was written in the Greek language. (Right now I am forgeting the exact number, but the Bible was written over the time span of like 1,500 years. I am also forgetin right now the number of authors of the Bible (There was only one AUTHOR that was GOD, but GOD inspiered like 57 diffrent people to dictate the Bible) Most of these people were not well know to each other (that is to say that the Bible was not written in a certain monistery) I do not know as much about Hebrew Language (but the words need to be read from right to left) But a more accurate way to translate what is said in the 10 commandments is 'thou shall not murder' which as you pointed out is quite diffrent than 'excuting' someone.
I feel that I am a little more equiped to talk about the Greek language, and the origional Greek writtings looked like this. -ALLOFTHELETTERSWEREPUSHEDTOGETHERWITHAHAIRSWIDTHAPARTANDEACHBOOKWASABIGRUNONSENTENCE-
I am not really interested in text criticism (but there are people that devote ther lives to discovering how to make the Bible easier to understand) But I want to point out something that I think is funny. There are people that try to claim that the Bible is completely filled with errors that have been placed in translations. But what thoes people do not know is that in 1947 some sheaperds fond some old writtings called the dead sea scrols. The funny part is that the writtings had been left untouched (Since about the time of JESUS) and many of the writtings mirror what is said in the Bibles that we have https://blog.oup.com/2017/04/contemporary-significance-dead-sea-scrolls/
Another piece of information that I want to include is that 'if' JESUS was not the SON of GOD, then the man was a crazy liar (how do you call a fraud a good man) Then a person would need to explain the odd phenomanon of people that are ready to die for a crazy man.
In this writting I would like to include one more piece of information. I have not read all of the writtings of Flavius Josephus. But I have read some of what this historian from antiquity wrote...and perhaps you will think that it is intresting also http://www.ultimatebiblereferencelibrary.com/Complete_Works_of_Josephus.pdf :)
