When we say how someday, when we die and are in heaven, we will be happy, why do we think we will be okay there and not here?

Why do we think heaven isn’t possible here? Why do we get upset that the world is in such a bad state all while we do little to nothing to make our own backyards better?

Didn’t we come to redeem the world? One pebble per person means mountains…

I wonder are we getting it right?
