A 3.5. I will bump up to 4. I am a huge Wiersbe fan. Love his commentaries. This book contains so much good information. My problem is, I was not sure what the theme or the direction of the book Wiersbe was trying to take with it. In some ways, you can argue it follows the same theme, but honestly, I felt it was a lot of good stuff thrown together. Worth the read, lots of insights on many topics, should be accessible in terms of depth to most, but could have been compiled better.
