I don't disagree, for parents that are able to do that. My sister did that were her kids for a time and then her husband decided they could no longer afford it. My husband and I had the boys for a week that summer when she told us they were taking them out of Christian school. I was very upset and felt in my spirit it was the wrong move. But I didn't have the extra money to help them. I still feel it was the wrong move but there is nothing I can do about it. But as I said, if I had kids they would not attend public school.
I did not teach lessons. They read books and the authors were their teachers. The only exception was the geography program and math program on the computer. Moses was not a good speaker and yet God sent him to speak to Pharaoh but God also provided Aaron. Most churches with 200 or more members will have a retired teacher in the ranks. You will have a few retired people who may be interested in coming out once a week to help.
