The book is based on God principles as being a parent. We have our own insights on how to raise our children. For instance, in the way our parents raised us. God is not with man-made philosophy or ideals. He is a Spirit, and they that worship Him, must worship Him in Spirit and Truth. John 4:24.
So in raising our children we must do it in the values and upbringing of the Lord. He will guide you into all truth. There are so many aspects and revenues in the way of parenting that we miss out on the big picture. Which is seeing the true aspect of nurturing and loving our kids the way our heavenly father loves us as His dear children.
He created us and knows everything we encounter in life and how to resolve every issue. So why shouldnt He know how to give us the ammunition we need in raising our children in the perspective of Him? Because with Him it is the right way to go. We can do everything in our little finite mind of what we feel is the right way to be a parent. But it always comes back to the maker, which is God. The ultimate parent of the whole universe. He will direct you in the way a parent should be. It is up to that individual to take heed of his word and direction for life as being a believer in Christ Jesus our Lord.
