The Lord sent a tremendous hailstorm. Pharoah told Moses, “Please beg the Lord to end this terrifying thunder and hail.”
Moses said. “I will lift my hands and pray to the Lord. The thunder and hail will stop, and you will know that the earth belongs to the Lord.” Moses lifted his hands to the Lord. The thunder and hail stopped (read this story in Exodus 9:23-33).
People who pray see God do amazing things.
