5. Heaven and Hell

Someone discussed the issue of heaven and hell with God. God said to him: "Come! I will show you what hell is."

They walked into a room. A group of people gathered around a large pot of broth, but everyone looked hungry and skinny.

Each of them had a spoon that could reach the pot, but the handle of the spoon was longer than their arms, and they could not put the soup into their mouths. I can't drink enough broth to my stomach. I can only look at the "soup" and sigh, but there is nothing I can do. "Come on! I'll show you heaven again." God led the man to another room.

Everything here is no different from the room just now. There is a pot of soup, a group of people, and the same long-handled spoons, but everyone is wide and fat, and they are singing happily about happiness. "Why?" The man asked in confusion, "Why can't people in hell drink broth, but people in heaven can?"

God smiled and said: "It's very simple, here , they all feed others.”
