The Barna Group, which studies religion and society, has released some devastating statistics about young people and their "Three Spiritual Journeys" away from the Church. The study divides these attitudes towards leaving the Church into three groups: Nomads, Prodigals, and Exiles. This has to be eye-opening about why we need evangelization. The Barna Group president is David Kinnemann, who authored this great book: You Lost Me: Why Young Christians are Leaving the Church... and Rethinking Faith.
The first group Barna studied was the Nomads.
The second group are the Prodigals.
Finally, the third group are the Exiles.
