Where did the Bible come from?
I wondered that as well, all of the books of the bible where written by people who believed and followed in Gods way and some of Jesus' deciples (I think).
However, back in the time of Constantine, it is said that Christianity was growing faster than any other relegion, so in order to keep peace with the people Constantine gathered all the judicial priests and so forth to put books written by the above mentioned so that the Christians would have a book of law to live by, however many books written by the deciples, including Mary Magdeline was kept out, It is also said that some of these books were written in a way to make Mary Magdeline and Jesus look bad, but in instamce Mary Magdeline was a decendant of King David himself and as well as Jesus so they found them to be a threat that is why Jesus was Crucified. Please so not quote me, I have learned most of this by watching history chanels and National Geographic, so please do more research as there is much more out there to go along with the Bible.
Please remember man wrote the Bible not God altough the Bible is supposed to be what God wants us to learn, but I say that if you want to have a good life and want to follow in Gods way, follow his Ten Commandments as these speaks the truth, no matter what way you put them.
