Biblically speaking, a man’s name is equal to his character (Proverbs 22:1). This is why God’s character is often defined by His name. Faithful and true are two words that describe the very nature of God, but they are also names by which the Son of God will be called at His second advent (Revelation 19:11). Even the name Jesus was associated with the person and work of our Lord (Matthew 1:21). These names, and many more like them, are well known to believers, but few know that the Lord’s name is also said to be Jealous. Why? Because that is who He is! He is the One true and living God who demands man’s sole attention. Just as He is Faithful and True, God is also Jealous.
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.
