[Book of Job] Why'd God take the bet?

Context:

Book of Job, in the Old Testament, the Devil tells God "I bet a pious dude would loose faith if everything went to shit. I bet they're only faithful when it seems to be paying off for them to believe."

God drops a series of horrendous events on Job, until he's utterly fucked with a dead family, and then turns up and spouts beautiful poetry about being inscrutible.... even as we the reader know it was a bet.

Now my question is very specific, why did God take the bet? My theory he was worried the Devil might call him chicken, Marty McFly style. But that's not very God like is it?

I'm also hoping the answer is a bit better than "so a book of the bible could be written about it."

(Pls not too much evengelicisim or christian bashing)

From what I've heard, in some Jewish traditions Satan is not a rebel against God, rather his role is like that of a prosecuting attorney.  His job is to argue against the worthiness of any given person.  Justice depends on a vigorous debate, to paraphrase SMBC.  The "test" was just part of the process, so that all parties present could be confident in Job's faith.

From a meta perspective, it was an early attempt to solve the problem of evil, telling readers that they won't always know why bad things happen to them but there is a reason.
