Ironically, some Christian schools adopt the same educational theories that have failed in the public schools, with a little Christianity tacked on. Others are going to the other extreme, concentrating on theology and morality but neglecting the other realms of knowledge, which are also under God's sovereignty. Another problem is that Christian colleges are nowhere as far along as classical Christian schools and many homeschoolers in forging academically superior alternatives to the educational establishment. They already know this stuff, and much more. Christians who take the lead in education may be hated in many circles, but will be indispensable.
Education is an absolute necessity for an advanced society.
Those who can read, write, think, invent, and create become the leaders and the culture makers. Then Christianity will once again lead the culture.
