Envy is not a synonym for jealousy. Synonyms can be used interchangeably; envy and jealousy can’t. If you don’t believe me, try substituting the word “envious” for “jealous” in the phrase: “For I the Lord your God am a jealous God.” Jealousy is possessive and protective; it can be good or bad. God’s jealousy – His possessiveness of His people – is a good thing; it protects us from being plucked out of His hand.
