The short answer is yes. Just like you did, your (kids) can turn out okay. Maybe even better than okay. But our arrival at a place called “okay” does not necessarily mean that all our choices along the way were the right ones, or that our educational experience was the best one.
The real questions are these: Are you the same person today that you would have been had you attended Christian school? And what about the journey that brought you here? Might it have been a little more joyful, a little less troublesome? Is it possible that God could have used you for His glory even more than He already has?
These are questions only you can answer, and if you haven’t already, why not do it right now? Give this issue an honest, thoughtful look, and then ask God what His will is regarding your children’s education.
