It's certainly a very long book and the language can be extremely hard to decipher. My personal opinion is that there are thousands of other books you could read which would be much more useful for your language studies.
However, if you are a practicing Christian then it's probably only fair that you read the Bible from cover to cover at some point in your life. Now is as good a time as any, I suppose.
If not, I personally wouldn't recommend it and if you do read it, remember not to take it as a work of fact. Consider it a very long story, made up by lots of people over a long time and to be a well-read work of fiction. (Please note, I am not making some kind of religious statement here - I'm simply pointing out that works of fiction are read differently to factual books.)
