Demanding high standards for our children is a noble thing. Demanding high standards while frustrating them in the process is foolish. In other words, our high standards need to be loving standards. We need to allow love to cover a multitude of sins lest we sin attempting to love.
In parenting, we need a healthy dose of humility. This is hard in an age when grades matter more than godliness; external obedience more than internal motivation. We cannot, however, allow our high standards to usurp the proper place for training in love. We need an end result where our children desire the good, true, and beautiful because they are infinitely better than the alternatives. It is possible that in our high standards we lose the purpose of the law: to direct our children to the God of the law.
