You have a class of young strong men and women, and they want to give their lives to something. Advertising has these people chasing cars and clothes they don't need. Generations have been working in jobs they hate, just so they can buy what they don't really need. We don't have a great war in our generation, or a great depression, but we do, we have a great war of the spirit. We have a great revolution against the culture. The great depression is our lives. We have a spiritual depression.
The rate of change is global now. I think there's a kind of mind that is so ill at ease with that transformation that it reaches out for something permanent. And religious faith offers that, from simplicities, which you are told are eternal and unchanging, and you can hold on to those like a life raft in a metamorphosing world.
