You are accusing the Christians who teach of perpetuating a godless, secular school system,
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The facts accuse them. That is exactly what they are doing if they teach in a godless school. They are cooperating with, establishing, and supporting schools that teach children to think and reason godlessly.
You know, the more I read your posts the more I am convinced it is you that have a “world” view. Your reasoning is all of this life. How can we make our schools better, or, if not shut them down? How can we wrestle these godless places to the ground? How can we berate Christians who dare go to these godless places to work in and, by their very presence, seem to support the notion of godlessness.
What is missing all the while from your arguments is anything from you about whether or not your God can do a work in these places despite the very godless nature of them by using His chosen vessels (Christian teachers) to serve His purposes and prepare souls for salvation.
The question is this: Is God capable of using Christian teachers to reach the lost in public schools? Yes, or no? If yes, then, support those teachers, while you do whatever it takes to bring about the change in public schools we all long for. If the answer is no, then you do not know the God of the Bible.
