Actually I'm doing the same thing you are doing.
When I read a religious writing that was written by someone who is alive now or someone who passed on years ago, I choose to agree with what that person wrote or I choose to not agree.
You have chosen to believe that the collection of writings that were picked by a committee of religious leaders to include in the bible is the actual word of God. I just don't trust others to tell me what I am capable of deciding on my own, that is, what religious beliefs to have and which not to have. I am not condemning you for your beliefs, I am just saying that in my opinion, the committee of religious leaders who said this is the word of God, and this is not, are capable of being wrong, just as all humans are capable of being wrong.
