The Bible stories aren't made up. But a prudent man conceals knowledge. You can actually hurt someone's faith by telling them the Bible is literal. Plenty of sound teachers taught the stories were emblematic, as it's the Law of God which prevails and converts the heart.
The issue is we have to engage with a generation that cannot believe in anything beside evolution, unless thunderstruck by God with the truth. We have to increase the scope of God, and decrease the scope of the Bible. Because the Bible's moral law is true, and imperative for human flourishing and survival. And also it's imperative for salvation. We're not reaching people right now, and we must, or all is lost.
