In the Greek mythology there is a story about summer and winter.
It's a story about Persephone. A daughter of Demeter. Persephone got kidnapped by Hades (god of the underworld). Demeter felt miserable and everything became dark and cold. Other gods came to help and made a deal with Hades. Persephone was allowed to go back, but she still had to eat one dinner where she ate six seeds of a pomegranate. She didn't know that once you ate something in the underworld, it wasn't possible to go back. Because of the deal the other gods made with Hades, she only had to stay for six months; one month for every seed she ate.
This story from the greek mythology explains the presence of summer and winter.
This is about my resurrection.
