The first part of this answer has to do with your role as parent. You are the God-appointed leader of your children, so it should come as no surprise that the overwhelming task of raising and educating them is in your hands. The Apostle Paul put it this way:
“Fathers, do not exasperate your children; instead, bring them up in the training and instruction of the Lord” (Ephesians 6:4).
The question is, what are you supposed to teach them? And God has a great deal to say about that. In Deuteronomy 11, for example, He says the education of children is a 24-hour-a-day, 7-day-a-week process that must take place from birth through maturity.
“Fix these words of mine in your hearts and minds … Teach them to your children, talking about them when you sit at home and when you walk along the road, when you lie down and when you get up. Write them on the doorframes of your houses and on your gates, so that your days and the days of your children may be many in the land that the LORD swore to give your forefathers …” (Deuteronomy 11:18-21).
Here we see God instructing His people how to live as they prepare to go into the Promised Land. Critical to the life and health of His people is the teaching of the Word of God by parents on a daily basis in every situation.
Here’s the problem. State schools fail to recognize the relevance of the book upon which you, as a Christian, have based your life. The question is not, “Should I consider Christian education?” but rather, “Why should I consider anything else?”
The education of children and youth must be based on God’s Word as absolute truth. If the school your children attend adopts any other approach, it is competing directly against your training at home, and ultimately, against the training God wants you to give them.
