In 1 John 2:15–17, the apostle writes to believers, "Do not love the world or the things in the world. If anyone loves the world, the love of the Father is not in him. For all that is in the world—the desires of the flesh and the desires of the eyes and pride of life—is not from the Father but is from the world. And the world is passing away along with its desires, but whoever does the will of God abides forever" (1 John 2:15–17). It is not the created world itself that is sinful but the rebellious anti-God system of the world. The spirit of this world that comes from the god of this world (Satan) is set against God and His ways (Ephesians 2:1–3; 1 Corinthians 2:12; 2 Corinthians 4:4). Believers are called not to be enticed by and to love these things but instead to live for God and the things that are good and true.
Even though we ought to love the people in the world and enjoy the good gifts God bestows on us, we must always be careful not to elevate any of them to first place in our hearts and lives. If we do this, we make a good gift into an idol. Our God is a jealous God and He forbids idolatry (Deuteronomy 4:24; 1 John 5:21). This is why it is so important for us to love God first and foremost. There is a reason the first and greatest commandment is first. In part, it keeps us from making idols out of who we are called to love secondly. While we enjoy and use the good gifts God has given us in this world, we must never make them preeminent. Jesus said that whoever loves their mother or father, son or daughter, or even their own life more than Him is not worthy of Him (Matthew 10:37–39). Our love for Jesus must be greater than our love for anyone or anything in this world. When we see a beautiful sunset, we don’t need to worship the sunset but can praise God for His beauty and creativity. When we find enjoyment in life, we can rejoice that God is a God who delights and who wants us to be joyful. When we work hard and accomplish good things, we can be thankful that He gave us the ability and rejoice that our work is fruitful. We do not need to make work an idol but rather use that, as well as all things, to be thankful to God, who gave us these good gifts while living on this earth. If we love the world predominantly—nature, pleasure, work, or anything else—then the love of God is not in us. To love God above this world we must continually renew our minds with the Word of God and set our minds primarily on what is spiritual instead of what is earthly (Colossians 3:1–4).
