John Piper's Taste & See (12/10/09) article, "Why Require
Unregenerate Children To Act Like They're Good?" It helps parents sort out the dilemma of teaching children who are not yet saved (unregenerate) to "be good," even as we know that without the Holy Spirit it is impossible to "be good."
Here's one pointed paragraph:
"No parents have the luxury of teaching their child nothing while they wait for his regeneration. If we are not requiring obedience, we are confirming defiance. If we are not inculcating manners, we are training in boorishness. If we are not developing the disciplines of prayer and Bible-listening, we are solidifying the sense that prayerlessness and Biblelessness are normal."
