That's what the devil does. That's what demons do. Notice what else demons had done. The text says, he was always night and day in the mountains and in the graveyard crying. Have you noticed how many people cry today.
Tears stream down their faces.
They cry over what the devil is doing to their daddies. They cry over what the devil is doing to their mothers. They cry over what the devil is doing to their children. They cry over drugs and they can't get out of the situation they're in. I m reminded of a young prostitute crying in a court room because here babies were being taken away from her.
