This is a book of 365 devotions, one for each day of the year. Each devotion is wonderful - they deal with things such as trusting God, not people-pleasing, knowing you're good enough, being thankful, God's comfort, God's promises, spending time with God, just to name a few.
This book is wonderful, because of all the negative impact and discouragement we all get in the world, we need to be reminded Who loves us and keeps us taken care of. There are Bible verses to back up each devotion.
Even though this book says "for kids", I feel that adults can also benefit from it. Even adults need encouragement, sometimes even more so than kids. Adults are the ones who have to worry about certain things that kids don't. And the way a lot of "adult" inpirational books are written, a lot of adults don't have the time or energy to read them. But this one is written in such a way that does not require a lot of time or energy. And, I don't think it is written all that "kiddy". An adult (or a kid) can read it at their leisure, take as many or as few "days" each day. Even if you only read one "day" a day, it will only take you a year to read the book, and get a lot of encouragement along the way, being reminded that God loves you, and you don't have to worry about anything but Him.
I love this whole book, and I could actually say that all the "days" are my favorites. But one "day" in particular that I consider one of my favorites, is September 7: "I Set You Free", in which we are encouraged to free ourselves from the guilt of our past mistakes/sins.
In this time of discouragement and evil, this book is refreshing and encouraging, regardless of your age. Kids and adults, I highly recommend this book.
