It's not a set of rules...

I reckon that Michael Jensen in his book “You: An Introduction” has one of the best descriptions that I have heard of what the Bible is. He writes:

“The Bible doesn’t come to us as a set of rules, nor is it set our like a New Age self-help book. It tells a tale. We could say it is the script of a great play. Its dramatist is the one who made everything (we use the word “God’ to refer to this person) – including the human being who are its actors. It is a love story – a true love story. It tells how this God loves people, and though they spurn his love, he goes to extraordinary lengths to win them back”

I think this could be a great way to explain what the Bible is all about to youth, & hopefully will encourage them to read it!!
