The world is constantly battling for our minds. We are bombarded with the world’s way of thinking daily. The evil one is seeking to hinder us in our walk with God. Our mind is the gateway for our actions and the way we think always impacts how we live. This is why having a worldview that is Biblical is the only consistent way to live in this evil world that we must remain pilgrims in. The battle for our minds is here.
Trouble of the World
What is the “world” in this sense? Is God’s creation evil since sin is in the world and we are told not to “love the world”? Let us look at what Scripture says about creation.
Then God saw everything that He had made, and indeed it was very good. So the evening and the morning were the sixth day.Genesis 1:31 (NKJV)
Now the Spirit expressly says that in latter times some will depart from the faith, giving heed to deceiving spirits and doctrines of demons, speaking lies in hypocrisy, having their own conscience seared with a hot iron, forbidding to marry, and commanding to abstain from foods which God created to be received with thanksgiving by those who believe and know the truth. For 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 Timothy 4:1-5 (NKJV)
In both these places we are told that created things are “good”. There is nothing that God has made that is inherently evil. We should enjoy those things that God has given us: the birds, the fish, the animals, all creation is ours to enjoy and it points back to the Creator who made it (Psalm 19:1). Now, how do we deal with passages that seem to associate the world as being bad?
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 lust of the flesh, the lust of the eyes, and the pride of life—is not of the Father but is of the world. And the world is passing away, and the lust of it; but he who does the will of God abides forever.1 John 2:15-17 (NKJV)
Adulterers and adulteresses! Do you not know that friendship with the world is enmity with God? Whoever therefore wants to be a friend of the world makes himself an enemy of God.James 4:4 (NKJV)
These passages seem very clear in the their indictment of the world. However, the “world” here (Greek word κόσμος) is not referring to the created world (as we have already established above) but the system that is opposed to the things of God (A Pocket Lexicon to the Greek New Testament by Alexander Souter is great for further study). The world is that way of thinking that is against God. Lust, pride, etc. are things that are of this “world” and are sin, and therefore “lawless” (1 John 3:4). These fundamental principles will help us to understand what it means to have our minds truly set on eternity.
The Christian’s Relation to the World
With this grim picture of the κόσμος, how are we to live? Unfortunately, the Christian tendency in running from the world’s evil thinking is to run from society itself. We create these “Christian” communities that have their own cultures outside of the society we live in. This principle is discussed by R.C. Sproul in his book Pleasing God. It is seen as being separate from the world and somehow biblical. That is not to say that cultures that Christians create are necessarily bad, but I think there is a tendency to do so as a reaction to the culture around them. Just look at the radical homeschool movement, where sending your kids to public school is sinful, women must wear dresses, and heaven forbid a woman work outside the home. And again, I want to be careful here. There are those who do so out of genuine conviction and there should be some sensitivity (this can be seen in Romans 14). But when these become the standard for obedience to God and are done in an unbiblical manner, then the matter changes, and this tends to be what happens when these “cultures” are created.
Christians are not to separate themselves from this world. Jesus prayed to His Father in the Gospel of John:
I do not pray that You should take them out of the world, but that You should keep them from the evil one.John 17:15 (NKJV)
It is not God’s will that we live in segregated communities apart from society. This is contrary to Scripture. Paul also makes the argument against segregation in 1 Corinthians:
I wrote to you in my epistle not to keep company with sexually immoral people. Yet I certainly did not mean with the sexually immoral people of this world, or with the covetous, or extortioners, or idolaters, since then you would need to go out of the world. But now I have written to you not to keep company with anyone named a brother, who is sexually immoral, or covetous, or an idolater, or a reviler, or a drunkard, or an extortioner—not even to eat with such a person.1 Corinthians 5:9-11 (NKJV)
Paul wanted to clarify what he was talking about. We would have to leave this earth to completely avoid them! It is the one who claims Christ yet shows no repentance that we are to avoid — church discipline is in view here. Also, how are we to tell the lost about Christ while we are separated from them! We would have to disobey Christ’s Great Commission in order to leave this world. Christians are to be living in this world and be a light in a dark place.
Using Our Minds Rightly
What does all this have to do with how we think about eternity? What we THINK or BELIEVE about our relation to the world will dictate how we live in it. If we think that the way we are to live with eternity in mind is to leave the world, we will have a warped view of what it means to genuinely have a heavenly mindset.
The one who is righteous follows God’s law and his MIND is focused on it. He is constantly meditating on it. His grounding in God’s law leads him to prosper and walk obediently. And where is God’s law found? In His Word. This is the foundation of how we are to live in this world and think rightly. This ultimately is where we should look and where all thoughts and worldviews must be vetted. Manmade rules of how we are to think rightly will never be able to compare to this and, in fact, do nothing to stop the indulgence of the flesh (Colossians 2:23).
Finally, brethren, whatever things are true, whatever things are noble, whatever things are just, whatever things are pure, whatever things are lovely, whatever things are of good report, if there is any virtue and if there is anything praiseworthy—meditate on these things. The things which you learned and received and heard and saw in me, these do, and the God of peace will be with you.Philippians 4:8-9 (NKJV)
This passage really summarizes what it means for us to have minds set on eternity. We are to think on those things that are good and our obedience to God will follow as a result. This verse is not forbidding the thinking of things that are evil (meaning thinking of the things themselves, not actually sinning in our thoughts) since this would require us to leave this world. The world is the devil’s playground, full of sin, and is opposed to God. It is necessitates mere thoughts of bad things by being in its presence. But as already discussed, we are called to live in it and it is not our Lord’s will that we leave it. The Scriptures themselves contain many instances where there are things that are not lovely, admirable, noble, pure, etc. Paul here is not creating a dichotomy between thinking of that which is good and not. What he wants is the Philippians to have their minds focused on the good so that it will change the way they live. The Reformation Study Bible notes on verse 8:
Concluding these exhortations, Paul calls his readers to a life of obedience, the right response to the peace of God. The virtues listed are not exhaustive but representative, and they come to expression in countless ways (note the repeated “whatever”). Thinking on such things is not an end in itself, but preparation for purposeful action (v. 9).The Reformation Study Bible, page 1724, English Standard Version
This is what being eternally minded means. This is how we are to walk. As our minds are properly set on eternity, our lives will follow in obedience.
A proper understanding of Christian living always should begin with God and work its way down to us. The practical nature of the Scriptures should leave us focusing on God without adding the fluff of our own extra biblical rules that have no grounding in Scripture. As we live out the practical nature of Scripture, we will be true salt and light in this dark world.
