Are we going to fail at times, you bet! Are our children, going to make wrong choices, you bet! None of us our perfect! But with God...So if you are looking for a tool to help you in this parenting journey, I would recommend this book. It will help you see the big picture of what God is inviting you to be a part of. There are 14 chapters, each one will introduce and explain a parenting principle and show the way of grace through it. The scenarios and problems the author shared are one's I related to. This is not a book to change your children, but for you, the parents. All changes come from one source and that is God working on the inside of us. Your best parenting tool, will be the Bible! Where else would the author suggest you go to, but to the ultimate source, God's Word. So another reason why I recommend this book!
