Randal Denny began a devotional study in the Book of Acts with 'Do It Again, Lord' (Acts 1-4), 'Where the Action Is' (Acts 5-8), 'Wind in the Rigging' (Acts 9-12), and continued it with this volume. This book is about joy, a certain kind of joy that comes from deep down inside--the joy of the new life in Christ. E. Stanley Jones noted, A strange, sober joy went across that sad and decaying world--joy that goodness was here for the asking, that moral victory was possible now, that guilt could be lifted from the stricken conscience, that inner conflict could be resolved . . . and that a fellowship of like-souled persons gave one a sense of belonging. It was Good News. And it worked! Acts 13 through 16, the scope of this study, traces the beginnings of that epidemic of joy, which spread so rapidly and so extensively that it has reached us today.
