Why would God write a book of lies and why would you worship such a being?

If the bible is book that is littered with stories that are pure fiction but that are conveyed in such a way to appear as legitimate, why would you trust anything else that it had to say? If you say some of it is true, is it only because it already agrees with you have decided for yourself to be true?

Christianity is about trusting in Christ for salvation. You cannot trust that Christ's saving work on your behalf actually happened or is good enough to do the job if you cannot trust the author of statements to that effect. Why should anyone believe that Christ's atonement is actually able to save anyone if in the same book that is written in, there are stories that are verifiably false?

The writers of the New Testament quote just about every book of the Old Testament. The writers of the New Testaments ask such question as "What doth the scriptures saith?". They treat all the books of the Old Testament as one whole work and equally authoritative. Those same writers tell me that Christ died for my sins and that sacrifice is wholly sufficient for my salvation. If they are wrong about all the books of the bible being equally authoritative, why should I believe that are not wrong about the sufficiency of Christs sacrifice?
