Why are modern people indifferent to eternal life?

I remember the answer to this question from personal experience, from remembering my earlier self.

Modern people are indifferent to eternal life because it is pictured as "more of the same - but forever"...

As nothing more than a continuation of this-life, as it actually is experienced by modern people...

Which life is purposeless, meaningless; and ultimately isolated and disengaged.  

Why, asks a modern Man, would it be regarded as good thing, eternally to continue a meaningless and purposeless existence? 

In other words, when my personal Life is already pre-assumed to be something that Just Happened as a culmination of science and randomness...

When my life exists against a backdrop of "the universe is dead and going-nowhere and I am a brief-insignificant nothing within this vastness of time and space". 

This is the official conviction of our civilization - taught from the highest to lowest levels, by those with greatest status and conferred authority.

And it forms the functional basis of all public and "objective" explanations and justifications from the major social institutions (politics, law, military, police, mass media, economics, science, medicine, arts, education etc, and also the churches). 

When human life is regarded as as thus futile; its continuation forever seems to most people like a prospect that would be more of a torment than a thing to be desired. 

In such a context, the core promise of Christianity has lost its appeal to the extent that most people think that - even if resurrected individual life beyond death could somehow be proved to be a real and genuine possibility - they wouldn't want it!

And would prefer the (supposed) assurance of a swift and painless death (i.e. euthanasia) followed by utter annihilation of consciousness. 

Such is the depth of our modern sickness of soul. 

Too deep to be touched by evangelism or apologetics - too deep to be touched even by the devout practice of any strict church Christianity.

Because the modern belief in purposelessness, and meaninglessness, and ultimate personal insignificance - is larger and more profound than our professed religions. 

Until we - as individuals - are able to build our religion on a foundation of ultimate reality having a direction, personal meaning, individual significance that we can choose from ourselves; then we shall not escape the vortex of modernity.
