Well I certainly hope that you are correct that “eternity is the opposite of what we have here,” for I have precious little by way of material blessings in this life! As I recall the good Lord said the same.
The Good Lord was the example: he lived a simple happy productive life here on Earth providing help and guidance to everyone who sought him. After all His sacrifice, He now sits atop all of creation. This place is definitely upside down from all that.
And it just irks the hedonists that people can be more happy than them without all their hedonist fakery, without their desperate fake fleeting feelings through drugs and material flashiness. The hedonists work so desperately hard for these fake things, and yet, simpler people are more happy and more content than they are.
The rat race of the hedonists is pure desperation.
