Personally, I believe all scripture is given by God and is profitable to the hearer, which also means I like to read my Bible aloud, unless I'm stand hunting.
I've noticed, for a long time, that if I have encountered an issue in working through a problem at work or home, if I start describing the problem to another, those audible words sort the thing out for me and provide the solution. I can't say how often that has been true, because it's been a lot of times.
Similarly, I believe reading the Bible out loud does the same thing for understanding.
I can't ever recall reading a passage and thinking, it didn't belong in the Bible. I appreciate Thomas Jefferson for the smart man he was, but believe the Jefferson Bible shows all men have fallacies.
I also believe everything the Holy Spirit will lead us in, can be backed up in the Bible. If it's extra-Biblical, it may be from a spirit, but not a Holy one.
