I think 90% of what is in the bible is flawed. 10% (Mostly in 2 Kings) might be right... but however it is good for two things: (possibly a third)
1. Historically it tells us what the writer (thus their culture) was thinking at the time and place they wrote it...
2. Western Culture and religion is based on it so it is wise to have knowledge of the work.
The possible third is that reading the bible makes one an atheist
