If I am correct that alienation is the major problem in modern societies, the Christian evangelism will need a new strategy.
What I am discussing is not a new way of reaching people, but what we say to people when we have reached them.
Alienation is partly lack of meaning, purpose and connectedness; and partly a general deadness, dullness, materialism and two-dimensionality in life and consciousness.
In other words alienations has (at least) two aspects: metaphysics and thinking
Modern metaphysics entails basic assumptions of Life as meaninglessness, purposelessness and our-selves as isolated; these are inescapable consequences because we have already assumed them to be reality.
Modern everyday work-and-leisure thinking is passive; lacks depth, breadth and scope; is disconnected and impatient; prefers novelty to creativity; prefers quantity to quality; craves stimulation over creativity.
Too often the observable Christian Life is every bit as alienated as mainstream modern life; or even-more-so, since the Christian is a hated or despised outsider with respect to the modern project.
Christianity is often presented as a set of beliefs - which are inserted into the typical modern mode of thinking; or practices - which (whether enjoyable or tedious) fail to provide any transcendent experience; or social engagements - that are just like other social engagements, but with different personnel.
In sum, observation suggests that most Christians think and experience in a manner qualitatively undistinguishable from that of mainstream modern secular people.
For a person living in chronic, demotivating, despair-inducing alienation - even-if ordinary Christianity gave everything it claims to give, it fails to address The Problem.
What the mass of modern people actually have is the Iron Cage of bureaucracy at work, the superficial distractions and shock-culture of the mass media in leisure, and the hedonism of (often sexual) relationships in their daydreams...
What people crave is a higher, deeper, richer, purposeful and integrated, more-divinely transcendent experience of living. Christianity can give this - to a partial but significant extent: That is the message evangelicals could attempt to convey.
Christian evangelism needs to show, and to provide the possibility of, at least some proportion of a person's individual experience becoming a real Life of meaning and purpose; in spiritually-felt connectedness
with people and environment and the divine; lived by means of an active,
satisfying, whole and creative way of thinking.
This comes from a mixture of new assumptions and a new way of thinking. That should be the content of evangelism.
To depict this kind of Christianity would be to offer 'a cure' for what most-people most-feel most-need of curing.
