This is one of the points this does not prove the Bibleʼs divine attribute, but it shows that it is at least an honest work. Throughout its pages, the writers and characters of the Bible were very open about their own sin and wrong doing, and did not care to make themselves out to be great people and therefore more reliable or persuasive.
You can contrast that with Joseph Smith who stated that he did more for the church than Jesus ever did1, Muhammad who some say was sinless, or Siddhartha Gautama who is hailed as 'the Buddha' which is a person who has attained full enlightenment.
For example:
If those who penned the words of the Bible were simply making it up, they would undoubtedly leave out any mention of their failures or flaws in effort to make themselves appear more trustworthy and therefore, their message more believable. But that is not what we see at all. So in a way, the failures of the Bible's characters, actually makes them more believable.
