"Christianity, if false, is of no importance, and if true, of infinite importance. The only thing it cannot be is moderately important."

The bible is either fully false or partly false, it cannot be fully true though.

Also, Christianity whether false or true has been important for centuries, it has influenced millions and still does though it has arguably lost its importance in recent times ever since the world wars happened. 

 

Christians call it the word of God, at least those I had to do with. So, according to them, it is 100% true. 

The bible cannot be partly true because then it cannot be called the word of God.

 

Also, well, only a few people were in the progress of selecting which scripts made it into the bible. Some of them which were left out of the new testament were also about the life of Jesus as a child. He was murdering other children which opposed him. So, they didn't liked that and only the "good" stuff made it into the new testament.
