David Kinnaman has this to say:
one of the key insights emerging from the tour was that “nomads, prodigals and exiles share something in common: being somewhere other than home. One of the characteristics of Millennial life has become the image of the traveller. They want to wander the world, both in real life and in digital ways. They want to feel untethered. There is a trend among young adults of delaying the pressures of adult life as long as possible; they want to embrace a lifestyle of risk, exploration and unscripted moments. At the same time, they want to be loyal to their peers. The generation has come to appreciate and take identity from a spiritual version of life on the road. In other words, it is a generation that is spiritually homeless.
“This transience stands in contrast to the staid, predictable, and often overprotective experience that most churches seem to offer. The gap is simple: Millennials are a generation that craves spontaneity, participation, adventure and clan-like relationships, but what they often find in churches are featureless programs and moralistic content. Leaders who hope to alter the spiritual journeys of today’s Millennials need to embrace something of a ‘reverse mentoring’ mindset, allowing the next generation to help lead alongside established leaders. Millennials need to find spiritual rootedness, but that’s not simply to preserve old ways of doing church.
Preaching Grace on the Square 
Perhaps young adults also need to hear from those of us whose own travels are grounded in the practices of the faith, and who are content to walk alongside them, rather than trying to lead them down a particular path.
Precisely. After all, “pilgrimage” is one of the oldest and most profound metaphors for the Christian life. Perhaps we need to take it seriously and live it, rather than talk about it.
