Your thoughts are clear to me. Interesting. But I want to say about trial and error in the upbringing of children and the experience of our grandparents. If we turn to the Bible, then many mistakes could have been avoided. Human pride makes us go our own, unique way. it seems to us that we are above that experience and the wisdom described in this book. But, I see young and old people in the Church, their whole experience was deplorable, as a result, they still turn to God for wisdom.
