In a stunning admission, William Lane Craig, in response to a question sent to him has acknowledged that he has no good answer to problematic Old Testament stories. He says:

When people ask me what unanswered questions I still have, I tell them, “I don’t know what to do with these Old Testament stories about Noah and the ark, the Tower of Babel, and so on.” So I find myself in the same boat as you, Jon. I don’t have any good answer how to resolve these problems. Yet these unanswered difficulties have not kept me from Christian faith or from abandoning Christian faith. Why not?

Well, a large part of the reason, as you note, is that the truth of what C. S. Lewis called “mere Christianity” doesn’t stand or fall with such questions.

In essence, he’s claiming that the problems with the stories in the Old Testament should not effect some beliefs of Christianity, so it’s okay not to have answers to those questions. The problem here is that they do affect core Christian beliefs, namely the reliability of scripture, the truthfulness of scripture, the preservation of scripture and even salvation as it pertains to Jesus’s ability to hold or share false beliefs:

Since I have good reason to believe in his deity, as explained above, I would sooner admit that Jesus could hold false beliefs (that ultimately don’t matter) rather than deny his divinity.

Apparently Jesus who is God, can have false beliefs that “shouldn’t matter”. In other words, it’s okay if “God as a human”, was fallible with respect to his own theology! Quite the disaster this is.

and God knows best!
