Different thing.
I have tried to get teens to read the Bible and I generally start the boys on the book of Judges and the girls on Ruth.
I had very good results. Once the children understand that the Bible is not just snippets of verse to be memorized but full of adventure, mystery, romance, poetry and war they begin to read it in full rather then just the bits that were required reading.
Yes. Also once nonbeliever read the stories it is possible they may ask themselves whether it is logical that the stories were just made up. If I would have made up the Bible there are many messy things I would not included - bathsheba, solomon’s 700 concumbines, etc. If one wants to make up a pristine religion why include all the warts?
