The goal of Christian education should be vastly different than that of the modern public school system.
The public school system attempts to provide education to help a child move forward in life - education means better jobs. Thus, the goal is humanist at its core. Pride of life is the essential motivator.
"The fear of the Lord is the beginning of knowledge." The goal of Christian education is to help a student see the glory of God through the humanities. This does not mean that the humanities should be ignored or neglected. Rather, they should be more deeply discussed as they wondrously display the magnificence of God. Students are still productive members of society, able to achieve the ability to support their family, able to graduate from college and enter a profession, but have a different world view.
However, our Christian schools have caved to peer pressure. Sports and other such non-essentials are now controlling the school systems. American entitlement mentality and pride of life coupled with comparisons have crept in to fundamentally change what the Christian school was originally intended to accomplish.
Now, we have many churches across these states who have a Christian school where little to no education takes place, students are simply buddy-servants to the pastoral staff and games and diversions dominate the day. The school is simply a "We are not bad like those public school kids" day care to shelter students from the evils of the public school. Every Christian school touts their kids as the best kids in their community, but, are they? Or do we simply mean that we are sacrificing to be separated for the sake of being separated and we really have no idea what we are doing here.
