old story with new aspects

You've read and told a story a thousand times - and then you find out there still is something more into it. That happened to me and my favorite story last weekend.
How many time did I tell the story of the lost sheep? I can't remember. For this last Saturday I was scheduled with the devotion for the parents day of the new fifth graders at school. I am not good with devotions for adults at all and I really prayed for the "right" thing to tell them. Thursday one kid visiting me at my office discovered the paper theater we made last year in Nepal after loosing our picture cards. Guess the story. The lost sheep. He was asking me for it and I told him the story and all of a sudden I thought: this is it. The devotion for Saturday. With the story this scripture from Isaiah 40 came to my mind, where it talks about God gathering the lambs and his arms and leading those who are with youngs. I like the German translation that says mother sheep (ewe).
So how to get this together? And what's the new thing about the story?
There are the 99 good, well behaving sheep, sticking to the rules, doing there homework and just acting how they're supposed to. And there is this one not behaving sheep, forgetting the homework all the time, bending the rules and just won't listen. Of course it gets entrapped in the thornes. We all expect this.
But you also can see things different. There are 99 kind of boring sheep, not thinking much for themselves, doing everything you tell them to do. Not very creative, but nice and smooth. And there is the one curious, creative, inquiring sheep, always ahead to find new things. And this one also can get entrapped in the thornes.
How to react? How to talk to a sheep like that? As mother sheep you are happ to have a experienced, good shepherd next to you to give you advice! And this good shepherd just takes the sheep out of the thornes, not asking why it got entrapped, brings it home and gently leads it the right path. I can imagine after the party the shepherd explained the rules again to the sheep, but first he takes it out of the thornes and just carries it along.
We who are with youngsters so need this experienced, good shepherd! Good thing we can work along with Him!
