Perfectly Jealous

Recently in youth group, the fact that God, is a jealous God, came up. It really struck me, because I 'knew' He was a jealous God, after all, I read it a thousand thousand times. But, I really got hit with it the other day. A common question, is that how can God be a jealous God, if He commands us to avoid jealousy, and it is cast into a negative light. I was confused about this, personally, for a while, until the other night.
If someone were to take away something from another dude, when it was rightfully the dude's to begin with, would it be right for the person who was robbed of to be jealous and concerned? Even angry at the person that stole from him? Of course it would, and that anger would be justified and granted.
However, it IS wrong for a person to covet, and become jealous of something that is rightfully another's. That is were the sin lies, and what God commands against. Jealousy over other people's possessions is evil, and sinful.
Now when you look back at how God is a jealous God, it all becomes slightly clearer. God is jealous for us, when we fall in to sin. He desires that wicked awesome relationship with us, and that is slashed when we sin. That is when God becomes jealous. But the best thing is, if ya look further into it, it shows just how much God loves us. He wants a relationship with us so badly, he wants to know us and help us. Praise God for His jealousy! Makes me wonder if that's why He is so merciful to forgive us as much as He does. Just think how pitiful we as sinful creatures are, and the ruler and creator of this entire gianormous universe and all the little atoms that make it up, forgives beings like us, for ruining it all time and time again. And He perfectly restores us, making us white as snow. How awesome is He? Man, it just blows my mind.
