I have an idea as I listened to near death experiences and they share a hint of what's awaiting us. In general, if you didn't do anything worth rewarding but still made it to heaven, you would be in paradise or the place outside of the city and you may have a small tent inside of the city as your home. They describe paradise as having beautiful lush grass, flowers, and massive trees. The temperature is a perfect 72 degrees and the sky is blue with no sun. God gives off the light.What do the treasures of heaven look like though? What are we earning? Approbation? Get-out-of-jail-free cards?
Now, I'll talk about rewards. Your home will be as big as your deeds or more precisely you'll like your home more the more love you showed. It won't necessarily be bigger as some people like small homes. Now the next part is my belief as I'm getting this from the fact that love is how you earn for heaven. Let's say you shared food with someone when you really wanted to eat the food. In heaven maybe you'll be rewarded with delicious dishes. If you washed the dishes on earth and you really hated it, you may have servants in heaven. If you spent time with your kids and you didn't really want to do that, you'll be able to spend time with beautiful angels in heaven if that's your thing. The reward corresponds to the love you showed. How you loved is how you'll be rewarded. I have a strong feeling that this is how it is because of the fact that in hell testimonies, they said the damned were tormented according to their sins. So, why would God not reward us according to our deeds which I think is also mentioned in the Bible.
