I cannot speak highly enough about this DVD series and study book. Tim Keller share the truth of the gospel in a way that calls us into a transforming relationship with Jesus and and calls us to transforming the world that we live in--which is the message of Christ and the gospel. He speaks with great clarity gospel truths that have been obscured by our religious jargon and luke warm Christianity.
While the DVD teaching is excellent, the study book material adds much more depth and thought to the issues that are presented and do a good job of personally challenging the reader.
This is excellent for a Bible study group or any other kind of group. You won't be disappointed.
