It is good to remember that however Christians educate their children (public, private or at home), they must be morally isolated from the world.
Be assured that public school will seek to isolate your children from Christian truth, undermining the authority of the Bible, trying to separate them from every Christian principle they have been taught.
Parents, teaching your children of their need of Jesus as Saviour is but the start of your responsibility. You must also diligently and daily teach them Biblical truths and precepts, enabling them to defend their faith against attacks of the enemy wherever they are met. Above all, instill in them love for the Person of Christ and His Word. Without this, no kind of schooling will preserve them from shipwreck.
