The promise of paradise
The promise of heaven is often best understood by those whose lives consist of chronic pain or poverty, because their situations lead them to put their hopes in eternity instead of continually trying to make this life meaningful & satisfying. They don’t try to do that in the first place, & therefore don’t struggle with the disappointment that life doesn’t meet their expectations the way “normal” people tend to do. Much of the depression that is so rampant in our privileged society could be alleviated instantly if the sufferers could learn to focus on eternity instead of this temporary (& frequently frustrating) life.
