I've been thinking about these verses...
2 Timothy 3:16 - 17 (KJV)
All Scripture is God-breathed
(ESV) All Scripture is breathed out by God
All Scripture is inspired by God
Imagine you and I have a mutual friend, Cathy. Neither of us have seen Cathy in a while... You mention that you are going to see Cathy and I say "Tell her I said hi!". So you get there and you say "Oh, I saw Dana and she said to 'tell you Hi'". Who told Cathy 'hi'? You did, with your mouth, but they were *MY* words. Because you voiced them does that make them any less mine?
So, if you believe this verse and it says all scripture is inspired by God. All is all. Then that means you believe the whole Bible, everything it says.
We can't pick and choose what verses we believe. We can't ignore the ones we don't like, the ones that condemn activities in which we participate. The Bible isn't a 'feel good' book that you can use to justify your choices by cherry picking verses or using bits and pieces of verses.
Either we believe all of it or none of it. There's no in between.
And our God, who is mighty enough and awesome enough to create the entire world in six literal days is Surely able to preserve His word for all time!
