Question: "What does the Bible say about jealousy?"
When we use the word “jealous,” we use it in a sense of being envious of someone who has something we do not have. This kind of jealousy is a sin and is not characteristic of a Christian; rather, it shows that we are still being controlled by our own desires (1 Corinthians 3:3). Galatians 5:26 says, “Let us not become conceited, provoking and envying each other.”
The Bible tells us that we are to have the perfect kind of love that God has for us. “Love is patient, love is kind. It does not envy, it does not boast, it is not proud. It is not rude, it is not self-seeking, it is not easily angered, it keeps no record of wrongs.” (1 Corinthians 13:4-5). The more we focus on ourselves and our own desires, the less we are able to focus on God. When we harden our hearts to the truth, we cannot turn to Jesus and allow Him to heal us (Matthew 13:15). But when we allow the Holy Spirit to control us, He will produce in us the fruit of our salvation, which is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control (Galatians 5:22-23).
Being jealous indicates that we are not satisfied with what God has given us. The Bible tells us to be content with what we have, for God will never fail or forsake us (Hebrews 13:5). In order to combat jealousy, we need to become more like Jesus and less like ourselves. We can get to know Him through Bible study, prayer, and fellowship with mature believers. As we learn how to serve others instead of ourselves, our hearts will begin to change. “Do not conform any longer to the pattern of this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what God's will is—his good, pleasing and perfect will” (Romans 12:2).
