Who is that teacher should be of your child?
If you look at Jesus, he had no curriculum and yet they were calling him the great teacher why?
If you look at the church leaders and Jesus, there was a big difference. The church leaders had written documents they were following but they were not the reality of life. But Jesus had no any written document, yet he had great teaching and lessons of what life is.
A great is the one who teaches the laws and principles of life and not just what the school has set to teach. This is why many graduates are facing the opposite life upon graduation.
So if a teacher doesn’t know how life is and its content, that teach is dangerous.
