This is all speculation on my part.
One thing I figure is that there are no bad things in Heaven.
You will never feel sad, angry, envious, disappointed, or worried when in Heaven.
You will never be tempted to sin.
You will never have low self esteem but will never have to do anything to avoid accidentally being boastful either. There are no accidents and there is no such thing as boasting up there anyway.
In fact, nothing will take an effort, but on the other hand, you will never feel lethargic or lazy. You will always be happy about what you are doing.
You will be able to do anything you ever dreamed of doing even better than you ever imagined. You will be able to play the guitar faster than John Petrucci, run faster than Cathy Freeman, leap over tall buildings with a single bound…
Everyone there will be nice to each other.
No one will ever get hurt, physically or emotionally.
No one will ever disagree.
You will never doubt - like thinking, what if this is really some kind of dystopia, like its as if we were all brain dead? No, you will be fully alive. You won’t ever doubt that you are in the best place you could ever be in.
One thing especially for us Aussies - you will be able to drink as much as you like and never get a hangover (-: What’s more, the beer will taste excellent - it will taste refreshing even though you have no need of being refreshed since you’re in heaven.
You know what? All the above would be good enough for me (hmm, talking about heaven makes me want to go there even more now!) But you know what else you get, over and above and better than all this?
You will see God.
