I am currently going through this study with my adult Sunday school class, and we are all getting a lot out of it. The personal testimonies are very moving, as are the clips from the Brooklyn Tabernacle. We had previously used Jim Cymbala's DVD series "When God's Spirit Moves" and found that both are equally well done. The messages on the DVD and the questions in the study guide have given us a lot to think about, and God is using these resources to draw new people into our group who have a hunger to get closer to Him.
I knew this study would be good based on Jim Cymbala's other writings, but it surpassed my estimation. While a very basic study, it is one of the best small group studies I have ever used. I have gone from praise and worship, to tears to deep reflection. I have been challenged to apply what I have studied. The material can be used as a 6 week study or if your group has time constraints almost each session can easily be split naturally into two sessions, thus turning it into a 10-12 week study, especially if your group actually prays together.
I purchased this for use at our new church as I had to leave the previous copy behind. Jim Cymbala is very inspirational in his own presentation plus he uses the testimonies of several church members that are also powerful in terms of their encouragement and inspiration. I've purchased many video series for use in Bible Study groups, and this remains one of my favourites if not THE favourite.
