What does this classical Chinese mean?

Great mortals face great events and want to know in advance the success or failure of good or bad luck in the future, but it is beyond people's subjective speculation, so they sincerely ask ghosts and gods. The ghosts and gods were moved by his sincerity, and decided whether to do it or not by the appearance on the yarrow. I ching said: "solve problems through divination", that's what it said.

I translated it for reference only.
