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.
A zealous person is contagious, both positively and negatively. The apostle Paul cautioned that the early believers had been zealously affected, but not in a good way. Those who opposed the gospel were adamant, yet they unwisely waged war against the truth. Night and day, they zealously fought in order to hinder the ministry of the believers. Ultimately, their zeal affected the people of God. These believers who started strong were hindered by the enemies' efforts to the point that it affected their race for the Lord (Galatians 5:7). Modern day enemies of the gospel are aware of this potential pitfall for the believers. They often display more zeal than those who knowingly possess the truth. Yet, today's passage also teaches that “it is good to be zealously affected always in a good thing.” Zeal breeds zeal. Zeal in righteousness will yield righteous results.
