Incredibly Biblical, Amazing Insights, Best Discipline Book on the Market. NOT ABUSIVE!!
Format: Paperback
The only reason people rate this book low is because it advocates spanking. Because spanking doesn't happen to be popular in our culture, and because people have been brainwashed to believe that spanking is abusive, people think this book is awful. If this is you, or you're not a Christian, don't even bother reading this book. It will just anger you, mostly because you won't understand it. BUT, if you are a Christian, and you want the most Biblically based instruction on RAISING your children, then this is by far the most incredible book you could ever read. This book is not about spanking. In fact, he only talks about spanking in two chapters. This book is about WHY and HOW to discipline your children based on what the Word of God says. It has been so impactful for me, that I would be willing to live my entire life over again if I could go back and have my mother raise me as this book suggests. I would be a different person today with a LOT less problems. The way Tedd Tripp explains authority and why we discipline our children is so different than most people have been raised. It's not because it's "out there", but because the church as mostly failed in helping us understand discipline and authority. For example (from the book), we are under God's authority, and God has commanded us to bring up our children in the training and instruction of the Lord (Eph 6:4). Our children are under our authority. So when we discipline them, it's not because we're angry or we want to 'show them who's boss', but it's because we are commanded by the Lord and we must be obedient to Him. Not only is this Godly, but it teaches our children about authority and changes the nature of discipline! This is just the tip of the iceberg on dozens of amazing concepts that I personally had never thought about before in my life. This book is very straightforward and easy to read. Tedd Tripp isn't a flowery writer and doesn't waste words. He's direct, to the point, and often doesn't even give examples (something I would have liked more of). But because it's so straightforward, it makes sense and goes fast. I plan on reading this book several times just to ingest everything it has to say. I hope every Christian parent reads this book; our society would change if it followed the guidelines laid out in this Godly, insightful book.

An Excellent Book
Format: Paperback
There are many things in life that are easy to do poorly but are much more difficult to do with excellence. It did not take me long as a parent to discover that it would not be difficult to raise children, but that it would be exceedingly difficult to do it with excellence. In the six years since my eldest child was born I have looked often for help and advice in becoming an excellent parent. Unfortunately my wife and I have received little mentorship in this area. Thankfully, there are many books written about this topic so we have often looked to these resources to provide the wisdom and training we know we need. Shepherding A Child's Heart by Tedd Tripp came to us highly recommended. In fact, I can't think of a book on this topic that was recommended to us more often. It is a book that deals with speaking to the very heart of your children. Realizing that too many parents react only to symptoms of underlying sin, Tripp attempts to help parents look deeper, to see that all the things a child says and does flow from the heart, for as Luke 6:45 says, "...out of the overflow of the heart the mouth speaks." If a parent can understand a child's heart and shepherd that heart, he can deal most effectively with a child's deepest needs. And through it all he seeks to keep the gospel central to a parent's calling and to a child's response. The book is divided into two parts. In the first, Tripp lays the foundation for biblical childrearing. He shows that the heart of bad behavior is a sinful heart. He discusses a child's development, showing that a child is shaped by various influences on his life and that a parent needs to help a child have a Godward orientation. He discusses authority and suggests that, despite our culture's disgust towards authority, a parent must assert himself as being in a position of God-given authority over a child. A child must realize that parents speak not of their own authority, but of God's. He also discusses goals, methods, communication and discipline. Where the first part of the book lays a foundation, the second part guides a parent through shepherding a child through three stages of development: infancy, childhood and teenagers. For each of these periods he suggests the training objectives and then procedures a parent should use to attain these objectives. A section I found particularly interesting, perhaps because I have young children, was the section dealing with punishment. Tripp advocates spanking as really the only biblical method of punishment (and certainly the only one that is specifically mandated by Scripture) for correcting young children. He lays out very clear circumstances in which children should be spanked and suggests many circumstances in which parents must not spank. He makes this type of corporal punishment very deliberate and very loving. He suggests that parents must be fully in control of themselves when they spank and must not be filled with anger. Parents do not punish their children out of anger, embarrassment or retribution, but to teach children that defying authority will bring about consequences. Children must know that God demands obedience to authority and that there are consequences for defiance. In his endorsement of this book Edward Welch wrote, "Dr. Tripp's material on parenting is clearest, most biblically framed, and most helpful that I have ever encountered. It has become the backbone of my own parenting." I agree entirely. Throughout the book Tripp focuses on Scripture and on the gospel. He focuses on human nature and on the grace of God in providing a solution to the needs of our children. I would not hesitate to recommend this book to any parent, and especially to new parents. Read it now, pray about it, and let God direct you to His ways of shepherding the hearts of your children.

Simply Superb and Fascinating (at least to me)
Format: Paperback
While some may find this book boring, I find it fascinating. Professor Hudson is not only a brilliant writer, he is a mind blowing researcher who references everything. I have become fascinated with things like the USA lend-lease program that the USA implemented in World War 2 and how it damaged Europe, Britain in particular. Hudson covers this in detail. My personal study of economics for years has focused on John Maynard Keynes vs. the "Austrian/Von Mises" school and their so called "free markets." Professor Hudson, who anyone who has an interest in economics should get to know, is a TRUE "free market" supporter, a TRUE supporter of classical economics and offers a third and viable alternative to both Keynes and the "Austrian" school. VERY different and oh so fascinating. I will be buying more of Professor Hudson's books and recommend that you investigate the writings of Professor Hudson and also that of his friend and fellow economist, Professor Richard Wolff.
