The keywords being the word of god, meaning coming from an almighty creator.
This subject shouldn’t even be debatable and this fact alone proves who was the author or in this case authors.
Why would an almighty god require imperfect humans to put down in writing what he could have easily done himself in less than a nano second. and preserve it intact and unchangeable is beyond me? He had to have known that this course of action alone would have cast doubt in mankind’s mind and heart as to the truth of his existence and what he requires of mankind.
Also many take for granted (myself included at one time) that the present form of what is considered the bible has always been. Yet all one has to do is actually research the matter to find that nothing could be further from the truth. Even today there is no clear consensus as to what books were inspired and should be part of the bible and which ones shouldn’t be part. This is not a matter of opinion, it’s historical fact. Looking at the motives of many of the early Christian church’s through critical eyes also helps to understand what motivated many to select or reject certain books, again historical fact.
For all I know the Koran was inspired and should be part of bible, why not the book of Mormon? Bottom line is god should have done the job himself if he wanted man to know the truth, it’s almost like he went out of his way to confuse mankind, pretty odd behavior considering how important the belief in him is suppose to be.
2/3rds of the world’s population practice religions that have nothing to do with the bible and of this group 75% have never read a bible that’s roughly 3 Billion people. Pretty interesting considering the bible is suppose to be the word of the one true god. One would have thought the word would have gotten around already, especially considering it’s been around in it’s printed form for 500 years.
