Ephesians 2:1–3 (NKJV)
And you He made alive, who were dead in trespasses and sins, in which you once walked according to the course of this world, according to the prince of the power of the air, the spirit who now works in the sons of disobedience, among whom also we all once conducted ourselves in the lusts of our flesh, fulfilling the desires of the flesh and of the mind, and were by nature children of wrath, just as the others.
For these first three Sundays in Lent, we are addressing our three chief enemies as Christians: the world, the flesh, and the devil. When we are outside of Christ, these forces dominate our lives and compel us to sin. Consequently, God must act to deliver us from their hold. And it is this that He has done in Christ. Listen again to Paul’s words: And you He made alive, who were dead in trespasses and sins, in which you once walked according to the course of this world, according to the prince of the power of the air, the spirit who now works in the sons of disobedience, among whom also we all once conducted ourselves in the lusts of our flesh… The world, the flesh, and the devil are a deadly trio. So what is meant by “the world”?
Unfortunately many Christians throughout history have misconstrued this warning against “the world” as a repudiation of creation itself. Worldliness, in this view, is any attachment to the created order or physical things: marriage, food, beauty, drink, sexuality, technology, etc. To be “heavenly-minded”, therefore, to escape worldliness, is to reject created things. But this is to misconstrue Paul’s understanding of worldliness. After all, Paul reminds Timothy, that “every creature of God is good, and nothing is to be refused if it is received with thanksgiving; for it is sanctified by the word of God and prayer” (1 Tim 4:4-5). The created order is not the problem.
So what is worldliness, then? “Worldliness is,” David Wells has written, “anything that makes righteousness look strange and sin look normal.” It is anything that makes righteousness look strange and sin look normal. The “world”, therefore, is not the created order or mere physicality; the “world” is the collection of assumptions, practices, and desires embraced by our broader community or culture that run contrary to the Word of God. It is the assortment of unbiblical values that strive to have preeminence over God’s values. It consists of ideas, institutions, and vocations that marginalize God and His law.
It is from this “world” that we have been delivered by God’s grace; and it is against this “world” that we are to do battle through the preaching of the Gospel. Paul reminds us in 2 Corinthians 10:4-5, “For the weapons of our warfare are not carnal but mighty in God for pulling down strongholds [institutions of the world], casting down arguments and every high thing that exalts itself against the knowledge of God [ideas of the world], bringing every thought into captivity to the obedience of Christ…” We are to do battle against “the world.”
But in order to do battle against the “world” out there, we must first do battle against the world “in here.” We must root out unbiblical manners of thinking and acting that characterize us individually and that characterize us as a congregation. We must strive to resemble not the kingdoms of this world but the kingdom of our Lord and Savior Jesus Christ.

And one of the first characteristics of the kingdom of God is humility – a willingness to confess our worldliness. There are many who would come here today and be asked to kneel and confess their sin and worldliness and recoil. “That is strange,” they would say. But in God’s kingdom, kneeling to confess sin is not strange, it is normal. “Worldliness is anything that makes righteousness look strange [like kneeling to confess sin] and sin look normal.” So reminded of our calling to fight against the world, let us kneel and confess that we often fail to do so.
