In The Last Days Terrible Times Will Come

The Bible is very clear that in the last days men will be lovers of themselves.  What does this statement mean?  What is it that God is telling us?  It seems that God wants us to know that spirit that is now at work in the rebellious ones will havoc the world, and men will be exceedingly violent as in the days of Noah.  God is bringing this hard and heartless age to a close by visiting judgement on the arrogant and rebellious ones.
