Well, I would add the question, who are parents enlisting as the tutor of their children K-12? In order for children to develop a proper understanding of the world from the Bible they must grow up in an education rooted in Scripture at home, at a Bible believing church, and the tutoring of a Christian school.
The one common denominator of adult Christians in our country is the secular based education received at the public-school system attended. The absence of focused training in Scripture (K-12) in the formative years of life is the primary reason adult Christian lack a Biblical worldview.
Consider another quote from Tony's article featuring George Barna who says:
"Believe it or not, he went on, a person's worldview starts developing at 15 to 18 months of age -- and it's almost completely developed by age 13. That's not a lot of time, and we -- as parents -- aren't the only influencers. There's the media, their friends, teachers, public officials. They all help shape their thinking about right and wrong, purpose, God, and life.
It all goes back to what Scripture tells us: if we teach our children when they're young, they'll return to it. But they're not going to return to that which they don't know. That's why it's extremely critical that parents take the leading role -- even in pre-school, kindergarten, and elementary school -- in teaching them a biblical worldview and helping them integrate that faith with the world around them."
I have shared this insight on numerous occasions, however, the average Christian parent does not understand how the lack of instruction in Scripture is disastrous for their children. Check out this feature from FRC and pass it on to others. Please don't neglect the diligence necessary to ensure your sons and daughters develop the convictions they need to bring them to Christ and a proper understanding of the purpose of life.
