This is an example of a person who is dissatisfied with what he has and stirs up others because of his ingratitude for what God had given him already.
The consequences of Korah's "taking action" are clear: God destroyed all these who rose up against Moses and Aaron—against Him. Does this pattern look familiar? It should. It is the age-old and oft-repeated sin of pride manifesting itself in ingratitude. Satan did the same thing (Isaiah 14:12-15; Ezekiel 28:14-17). It was not enough for him to be a covering cherub at God's throne. It was not enough to have the lordship over the earth and one-third of the angels (Revelation 12:3). No, he wanted to resemble or compare to the Most High (Isaiah 14:14)! His pride led him to go to war against God, a battle he soundly lost (Luke 10:18). Revelation 12:7-10 prophesies that his pride will drive him to attempt another coup d'état before Christ's return.
This is where ingratitude can ultimately lead a person: into total rebellion against God. It lends to an individual feeling a false sense of worth, that he deserves more. If not checked, it becomes a plague of discontent that soon infects others, as Satan's ingratitude spread to other angels.
If this kind of attitude lands us in trouble, just what should our attitude be? A truly humble and grateful person will never rebel against God because he knows that even the very breath he breathes is a gift and calls for praiseful thanksgiving to the Father. Sharing this thanksgiving with others in the church works like soothing oil that helps to heal the body.
