What scares me about this, particularly as a parent, is not that my kids will be led astray by hypocrital Christians they meet or overly strict Sunday School teachers. My fear is that I will prove no less hypocritical... that the religious education my children receive, whether around the dinner table or at church, will lead them to empty rituals instead of fulfilled relationship. Of course I have the best of intentions for my children... but anyone who admits the existence of Truth must also admit that good intentions are not enough. I don't doubt for a minute that our local Christian high school was founded with the best of intentions. And yet, in the minds of the students I spoke with, the beauty and truth of the gospel has been reduced to a set of motions one must go through. [To be fair, I have also met students from this school who love Jesus and have been radically changed through their relationship with Him.]
Getting back to my point, parental (or institutional) good intentions are not enough. Intending to teach your children the truth about God does not guarantee that they will get it, and apparently they may end up resenting you for it. So what is a parent to do? Some parents take the 'let them find their own way' approach, based on the idea that religion is something everyone has to discover for themselves. I can see where these parents are coming from, to some degree. But how could I hide the love and grace of God from my children? It would be like withholding food from them on the grounds that it will taste better if they go out and find it for themselves. But at a certain point (and here's the hard part), kids need to start making their own PBJ... and making their own choices. I can teach them everything I know about fiber and protein and trans-fats, but I can't and won't go off to college with them and make sure they eat right in the dorm cafeteria.
So I guess that is the same approach we will take with spiritual matters. By our lives and our words, we will testify to our children the love and grace we have received through Jesus Christ. We will pray for them, hoping that as they start making their own choices (and their own PBJs - yay!), they will respond to the good news they have heard and follow Jesus. What happens if they don't? That's a question I don't have answers for.
