Of course men wrote the Bible. Who claims any differently! The implication here is that the bible is not from God but just a man-made book. But just because men wrote the bible does not mean God did not have a hand in its authorship. If God can create the Universe, can’t He inspire a select number of people to accurately write down some books for Him?
2 Timothy 3:16 “All Scripture is given by inspiration of God, …”
Matthew 7:12 “So whatever you wish that others would do to you, do also to them, for this is the Law and the Prophets.”
When I read other peoples writings, I do not convict them as being guilty of lying until proven innocent, in part because I don’t want people doing that to me. Therefore, people who also hold to the Golden Rule should extend the same liberty to the bible as they do their own writings.
