I am not sure of what you are asking? If you are concerned about your child's education within the secular environment then I guess you are not alone in your worries. I think you need to pray about this and continue to educate you child about the gospel. Living out your beliefs has a big impact upon those who see you day in and day out. I know people who send their kids to Christian schools. Does this mean kids will turn out for the better? I am not convinced that this is a cure all as our lives are not ever completely determined by our environments. Our wills are our own and our loyalty is ours to give to whatever or whomever we chose.

Fear destroys faith. The best you can do is set a proper example, and trust God for the rest. I gave my children to God as each of them were born. And no matter what I see, they belong to God. That is my right, and responsibility, to both God and my children, and if I worry excessively about their relationship to God, I open the door for the enemy to buffet them. As their parent, Satan can get to my children in a powerful way through my fear. Faith precludes fear and doubt.
