Good book! He spends a lot of time talking about repentance and faith (believing) and how they're two sides of the same coin. He also talks about the transformation that occurs when a person is genuinely saved. I wish he would have addressed the carnal believers in the Corinthian Church and given his thoughts regarding whether he thought they were saved or not! That would make a good subject for the author's next book!
This book comes HIGHLY recommended by me - someone who first accepted Jesus into my life at 15, but have had doubts about whether I had done that or not ever since. I also have asked Him into my heart again and again. This has helped me remember to REST in the completed work of Jesus. My only regret is that I didn't purchase the hard copy book because it was hard on my iPad going back and forth from the footnotes.
Growing up in the church, I went to the altar countless times asking Jesus into my heart. I wanted to be sure. After taking discipleship classes and Bible studies, I finally realized He had been there since the first time I asked. Too bad this book wasn't written way back then! Reading it actually made me laugh, as I thought back to my own experiences. I enjoyed the book and would recommend it to those who might not be sure.
I got this book because many of my friends are dealing with the nagging doubt of their salvation. Can't say that the thought has not crossed my mind before either. The book lays some foundation for committing a person's salvation and will be a good reference to provide someone you know who is wrestling with doubt. The book is practical and useful.
