University undergraduates have both the freedom and the bandwidth required to consider abandoning one comprehensive set of beliefs about life and adopting a whole new one. Later in life their worldview “settles in” through vocational choices and longer-term friendships and new family ties. This makes it far harder to get anything like the focused attention and energy necessary to examine the foundations of one’s entire life. The university, then, is in many ways uniquely suited for evangelism. There’s no other place in our culture that affords listeners the space and freedom, time, and posture to talk about the Meaning of It All.
