What's the Biggest Problem in the World?

From the Christian perspective, what do you think is the biggest problem in the world? Here's a list of some big problems. Am I missing anything? 


Worldwide, there are currently:

300,000 child soldiers
1.25 million who die each year from malaria
2 million child prostitutes
6 million children in slave labor
8 million who die each year from hunger or hunger-related problems
40 million people with AIDS
165 million child laborers
210 million orphans
250 million children without access to school
1 billion people without access to clean drinking water
1.4 billion living below the poverty line
1.6 billion unevangelized (never heard the Gospel of Jesus Christ)
2.7 billion unreached (live among people who rarely if ever hear the Gospel)
5 billion not saved (Just a guess. Only God knows who's written in the Book of Life)


I think the numbers are pretty clear.


Strive to look beyond the physical problems of the world to also consider the spiritual problems of the world.
