Historically, the word jealous is connected to the word zeal rather than to envy. Unfortunately, the world has perverted man’s understanding of jealousy by likening it to a detestable sin. The Bible student recognizes that jealousy cannot always be sinful because God says that He is a jealous God (Nahum 1:2) and God does not sin. A scriptural study proves that jealousy can be righteous, or it can be wicked depending upon the intent of the one in whom this jealousy originates. In a very basic sense, jealousy is the unwillingness to share or allow anything to rival the object of one’s desire. Since man has sinful desires, jealously is often viewed as sinful and can lead to other sinful practices. In the Lord’s case, His righteous desire to be man’s only true and living God drives Him to just judgment and godly jealousy.
Since God is “a God of truth” (Deuteronomy 32:4), it makes sense that the words proceeding forth from His mouth would reflect and demonstrate the same nature as their author. According to the scriptures, this is exactly what has happened. The psalmist said, “thy law is the truth” (Psalm 119:142) “and all thy commandments are truth” (Psalm 119:151). The Lord Jesus confirmed this when He said, “Sanctify them through thy truth: thy word is truth” (John 17:17). If God is worthy of praise for being a God of truth, it only makes sense that His truth would also be worthy of man’s praise (Psalm 71:22). God, knowing this truth, magnified His word above all His name (Psalm 138:2).
