One thing I have learned is that not everything is as it seems....I learned this first hand working in the area I work in where I am privy to private medical records (including psychiatric) in a small community.
We see the outside of everything....but no matter how well you know someone, the intrinsic dealing within their family and personal life is something that is generally really private.
So, I judge very little by outward appearance.
I will say that in reading the Pearls materials and studying their doctrine versus the Bible, they are false teachers.....they project a humanistic condtioning method of parenting...not a Biblical one. The saddest thing to me is that I see very little Gospel in their teaching.....which is the cornerstone of our faith....how can you parent without a strong foundation in the Gospel? I simply do not understand.
