The Veggietales situation as well as an interesting discussion on the homeschool forum that I seldom wish to be snarky on reminds me of one of my ongoing issues as a parent: What is the point of teaching children to behave?
Yes, I have to think through things like this. I cannot do something consistently if I don't have a good reason for doing it. When the children were very small, this lead to conversations with Wondergirl like this:
Wondergirl: Are your children allowed to climb on the coffee table?
Me: I don't know, none of them have gotten up there before. Let me think about it.
Child, falling off the table: WAAAAHHH!!
Me: OK, that's a reason. I guess not.
When it comes to moral behavior, though, I think it's an especially important question. Not only is it important for me to be clear in my mind why I am requiring good behavior of them, it's important for me to communicate it clearly to them.
Most of the books about how to be a Good Christian Parent take the duty of inculcating moral behavior very, very seriously, but I'm not usually very comfortable with the idea of why. Are we hoping to make our children better Christians by teaching them to behave? Well, that's patently wrong. Anything that gives them the impression they are more acceptable in God's sight because they behave themselves is just raising a little Pharisee who won't even think they need a savior. (And, as icky as I find it to imagine saying, "You make Mommy very sad when you do that," I find it ten times ickier to say, "You make Jesus very sad when you do that," as if Jesus gets his feelings hurt and is going to sulk until we apologize nicely.)
Then there are the people who come in opposition to that to say that the point of our parenting should be to reveal to our children just how evil their little hearts are. If we come down off Mount Sinai with smashing tablets, or just preach a come-to-Jesus sermon every time they slug their little brother, we may, someday, lead them to cry 'mercy' and find Jesus. While this has some internal logic, I have yet to see it be effective in practice, leading usually to children who simply give up before they get to the grace part.
I am not the Holy Spirit. I cannot convict of sin. I cannot bring repentance. I cannot bring forgiveness. I cannot bring sanctification. I am just a fellow sinner and recipient of grace, sharing what I know.
So what's the point of teaching them to behave? It's kind of like the exchange between George Bailey and Clarence in It's a Wonderful Life:
George: You don't happen to have 8,000 bucks on you?
Clarence (chuckling): No, we don't use money in Heaven.
George: Well, it comes in real handy down here, bud!
Good behavior isn't needed for Heaven. But it comes in handy down here. It's not always the easiest or most pleasant thing to do, but overall, it was given to us for our good. And knowing about what is right helps us understand more about who God is--about the beauty and order and relationships he made us to have.
Ultimately, we learn to behave simply because it's right. You don't hit your little brother, not because of how it makes Jesus or Mommy feel, but because it's wrong to treat other people that way. Jesus can take our badness (in fact, he already has), but little brother is smooshable and needs to be treated rightly.
