I purchase this book for my kindergarten boy. I want him to understand God in a very practical, personal and real way. This book is a fun, short but complete, way to introduce him to the New Testament. So far, we read a kid's Bible and it's mostly stories. But this will go over the all the books in 25 lessons for a more complete understanding of Jesus's story and his church. This is not too in depth, but considering the primary level target age, it is enough. I love the attention to detail from this company. The book starts with a bookshelf for the kids to put each book sticker after each lesson. The lesson itself is not long. As a parent, you read all the text, then look for 3-4 Bible verses (this is a good way to open to Bible and make your child help you look). After a short discussion, your child does an activity page which is simple, like a drawing or coloring, simple writing, matching lines, etc., one per lesson. The study finishes with a simple prayer and putting the sticker in the bookshelf. For the price, it is a great way to learn about Jesus and the church. I saw that they have a parent book. I was thinking that any adult who is not familiar with the Bible could use this study to learn about it in a very easy way. Great product from this company.
