Why does God hate grumbling so much?


Korah son of Izhar, the son of Kohath, the son of Levi, and certain Reubenites—Dathan and Abiram, sons of Eliab, and On son of Peleth—became insolent and rose up against Moses. With them were 250 Israelite men, well-known community leaders who had been appointed members of the council. They came as a group to oppose Moses and Aaron and said to them, “You have gone too far! The whole community is holy, every one of them, and the Lord is with them. Why then do you set yourselves above the Lord’s assembly?” Numbers 16:1-3
            In the story of Korah and his family, God punished them for grumbling against Moses, the leader God put into place.  Korah’s party felt they were superior and deserved to be put into position.
            God had them swallowed up in the earth, while consuming others with fire.  Then, when the people were upset at God for the way He handled Korah, God sent a plague that started to consume them.
            Grumbling splits unity and creates chaos.  God hates that.  He wants people to follow Him and that means following the people God has put into place.  By grumbling, the people were saying they didn’t trust God or the people He put into place.  God needed to punish them quickly before the disease of disunity spread too far.
