thats a pretty big assumption that god did not preserve the message he gives in the bible. its like calling dna "junk".
everyone who is intended to get the message will find it. christianity is a made up religion. take the bible and make your own unique religion. cant do any worse than those who have come before have done.
but just like the deafness that children display to their parents, people dont listen and they dont obey. how the hell can they get anything out of that?
