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.
The Bible associates love with action. In this passage, the Bible speaks of the believer’s love for other believers, relating it to the Lord’s crucifixion. If a Christian knows and recognizes the love of God, it should drastically affect his relationships. He cannot deal with others as the world would because the love of God has formed compassion within in his heart. This matter is so important to the Lord that He provided believers with a scenario to help judge their level of compassion. The book of First John says that if a brother has a need, and another brother can help him with his need, yet refuses, he lacks compassion (see also James 2:15-16). Therefore, one’s deeds, not simply one’s words alone, demonstrate true love!
