We're going to be surprised when we discover that things in Heaven are normal and natural, much like this life. Of course, it will be better, much more beautiful and supernatural, without all the troubles, trials, tribulations, suffering, tears and pain we have here. However, it will still be enough like this life that we will survive the change and not suffer some sort of traumatic culture shock. It'll be life very much like we're living now, only without the bad and evil.
