Query: It is worth every penny

The content is Biblical (I've read the Bible several times so I can testify). It is practical (with real examples and ideas) It is both: challenging and encouraging. It teaches to discipline fully in obedience to God and love to the children. It does not teach to abuse a kid at all. As a matter of fact there is a whole chapter preventing that.
