...is not, to ensure that their child never comes into contact with sin rather, it is to train them to respond biblically to the inevitable sin they will repeatedly encounter. Any parent who thinks that they can keep their child/children from experiencing sin (even if they home-school) is preparing for the kind of heartache that is heartily dished up in a Tolstoy novel. As Chesterton once observed: original sin is "the only part of Christian theology that can really be proved" and I'm sure he'd been visiting the local Sunday school when he said this. Or to paraphrase the Bible, man is born to sin as sparks fly upwards. And therefore, when embarking on a distinctly Christian education (whatever forms that takes) one must do so fully aware that children will encounter sin - in the classroom, on the playground and in the curriculum - and accordingly offer them, the tools/platform to respond biblically.
