When God sent the ten plagues on Egypt it must of been brutal not having water and the other nine plagues. It was because people in that era put their faith in Pharoah but they couldn't do a thing about it. Now this is how Satan was powerless the ten plagues came to those who chose to ignore God. But the prince of darkness could not prevent God from sending these things down. Nor did he have the power to stop God from writing his ten commandments as well as Moses bringing them down from Mount Sinai declaring God's laws.
