Stealing Glory

Our God is jealous for his glory. Jealousy is usually seen as a negative thing. God's jealousy for his own glory, however, results in our ultimate joy. We do not find happiness by diminishing or neglecting God's glory- but by enjoying it and celebrating it. In Hebrew, the word glory= greatness or weightiness. Much like the word "great" in modern English, glory could mean impressive in a general sense, or it could mean physically fat.

In 1 Samuel 2, we get the report that Eli's sons are stealing meat before the fat has been cooked away. God makes it clear in chapter 3 that he is going to judge Eli and his sons for their sin. Eli is the classic "passive" father who shakes his head, but does not restrain his sons.
In chapter 4, the Philistines defeat Israel in a battle, so Israel decides to bring out their token of God's glory (the Ark of the Covenant), to add a little greatness to their side. God makes it clear that His glory is not something to be manipulated. God allows the Israelites to be defeated, the Ark to be captured, and Eli's sinful fat-stealing sons to die.
When Eli hears the word of the defeat, he "fell backward off his chair... His neck was broken and he died, for he was an old man and heavy (fat/glorious)." (1 Samuel 4:18)
Then his grandson is born, and just before dying in child-birth, the mother names him "Ichabod" which means "no glory" and she said, "The glory has departed from Israel."
God is jealous for his glory- not just because it rightfully belongs to him, but also because it is the true source of our joy. When we steal glory for ourselves, it brings pleasure for a while, but eventually our necks will break under the weight that we cannot bear and our children will be called Ichabod.
