The Price of Favor-WWWJS? by Dan Solomon
This is a great book for any modern church's teen or adult Bible class. Of course, it's good for use at home as well. The author speaks from experience and from the heart. He came from a poor, abusive home and thought there was no hope for the future. But he found the Lord, and happily serves Him now. In this book, he touches on love, forgiveness, prayer and fasting, among other things, and backs up his feelings with scripture verses. You don't have to belong to a specific denomination to reap benefits from this insightful book a spiritualist will find it enlightening as well.
