Huh. Never read that verse before. Thanks.
I do what I can.
First of all, "jealousy" and "envy" are synonyms, so it makes no sense for you to say that it's okay for God to be jealous but not envious.
Second of all, isn't jealousy a sin? So are you admitting that God is sinful, since he's jealous?
So you didn't bother checking out the definition I referred to. . .
3. vigilance in maintaining or guarding something.
This is the context that God's jealousy is always in. Don't you know that language changes over time? Jealousy and envy were not always synonyms. I know this because throughout the King James version of the Bible, jealous(y) is always in the context of marriage, except for once in the Song of Solomon (which particular context I don't fully understand). Usually, it was God's rightful anger over the people of Israel (who were spiritually married to God) committing spiritual adultery with other gods (gods that didn't even have any power). The rest of the instances are of a husband jealous over his wife's adultery, and rightly so.
Neither of these describe envy, so at least within the pages of the bible, jealousy and envy are not synonymous. And apparently, contemporary English has just abandoned the sense of the word without giving the definition to a new word.
So no, jealousy, in the biblical sense, is not a sin because it is not envy, and there is no verse or passage which says jealousy is a sin.
Third of all, couldn't God just destroy Satan if he really wanted to? After all, he created Satan, so he should be able to destroy him, too. So why, then, does God choose not to destroy Satan?
Rev 20:1 And I saw an angel come down from heaven, having the key of the bottomless pit and a great chain in his hand.
Rev 20:2 And he laid hold on the dragon, that old serpent, which is the Devil, and Satan, and bound him a thousand years,
Rev 20:3 And cast him into the bottomless pit, and shut him up, and set a seal upon him, that he should deceive the nations no more, till the thousand years should be fulfilled: and after that he must be loosed a little season.
Rev 20:4 And I saw thrones, and they sat upon them, and judgment was given unto them: and I saw the souls of them that were beheaded for the witness of Jesus, and for the word of God, and which had not worshipped the beast, neither his image, neither had received his mark upon their foreheads, or in their hands; and they lived and reigned with Christ a thousand years.
Rev 20:5 But the rest of the dead lived not again until the thousand years were finished. This is the first resurrection.
Rev 20:6 Blessed and holy is he that hath part in the first resurrection: on such the second death hath no power, but they shall be priests of God and of Christ, and shall reign with him a thousand years.
Rev 20:7 And when the thousand years are expired, Satan shall be loosed out of his prison,
Rev 20:8 And shall go out to deceive the nations which are in the four quarters of the earth, Gog and Magog, to gather them together to battle: the number of whom is as the sand of the sea.
Rev 20:9 And they went up on the breadth of the earth, and compassed the camp of the saints about, and the beloved city: and fire came down from God out of heaven, and devoured them.
Rev 20:10 And the devil that deceived them was cast into the lake of fire and brimstone, where the beast and the false prophet are, and shall be tormented day and night for ever and ever.
God will punish Satan, keeping him away for ever, but in His own time.
