I see and hear this sentiment from parents a lot. It is the idea that children are hard-wired to challenge what they have been taught--that it is only natural for them to rebel as they get older. Many parents seem so convinced of this that they anticipate it long before it shows any signs of happening, and as a result I think they actually start pushing their children towards questionable choices in behavior, clothing, music, and more. It happens with young children as well as older ones. The 6-year-old girl sasses her mother and instead of being chastised and immediately put in her place she is celebrated and giggled at for being such a spunky little wisecracker. The 13-year-old selects low-ride short shorts on a shopping trip and instead of putting her foot down Mom shrugs and pays for them because "I guess that's what all the kids are wearing now."
The thing is, that's not what all the kids are wearing. Mine isn't. (Nor does she want to.) My kid also isn't talking back. Well, maybe the 8-year-old is sometimes. We're working on it. ;-) But having seen two children almost through adolescence with one yet to go, I refuse to accept the notion that adolescence is a time of life when, no matter what I do, my child is going to suddenly turn into someone unknown to me. I understand that sometimes things happen that we could not have predicted. Sometimes despite all our best efforts our children choose a foreign path. We are, after all, sinners in a fallen world. But far from its being the natural course, I believe it is unnatural for humans to reject their upbringing. Children who have been brought up to travel a certain path and who are repeatedly pulled back on to that path by determined, caring parents are much more likely, even if they briefly wander, to return to what they know to be safe and right and true than they are to head off into the woods.
I know I'm preaching to the choir here, but for what it's worth, here's my plea: Parents, please give your children credit for being the thoughtful, discerning, smart people you are rearing them to be. Respect their good taste, intelligence, moral compass and maturity. Don't write them off as hapless victims of the culture monster. Give them the best and expect the best in return. In my experience, not only will they continue to hold firm to the storehouse of intellectual and spiritual riches with which you have provided them, but they will go far beyond it, contributing their own discoveries and observations, which will in turn come back to enrich and edify you. And why should it be otherwise? They're your kids, after all.
