Our work in heaven will be free from any of the drudgery that we face here doing work.
Things that cause us not to like working will be taken away.
There are not traffic jams on your way to work, you love all your co-workers, you get along perfectly with everyone and the actual manual labor you do, is rewarding.
Imagine going to a job that you love and there is nothing at that job that you dislike? Every project done in advance, without mistakes, the boss loves it and you get a raise every day?
Well you probably won’t get raises, but you won’t care because you love it so much.
