1 John and chapter 2 beginning in verse 15:
And we find here, what is in many ways, a very controversial text, but I think it is a text critical for our day. And I will explain why. First, let us look at it beginning in verse 15 “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 the 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." In one way, this passage seems like it ought to collapse under the weight of other texts. It appears to be completely out of place and  almost contradictory in light of the fact that we as Christians are not just lovers, we are  profligate lovers. We are called to love like nobody's business. We love because God is love.  We love because God first loved us. We love the Lord our God with all our heart, soul, mind, and  strength, and we love our neighbor as ourselves. There are myriad commands to love one another. In fact, that is how the world knows that we are Christians, by our love and our love for one another, but not only our love for one another, we love our enemies. By love we fulfill the law. The Apostle Paul says  in Romans 13:8 to 10, "Owe no one anything, except to love each other. The one who loves another has fulfilled the law. For the commandments, ‘You shall not commit adultery, You shall not murder, You shall not steal, You shall not covet,' and any other commandment, are summed up in this  word: 'You shall love your neighbor as yourself.'   
Love does no wrong to a neighbor; therefore love is the fulfilling of the law."And then there is the issue of the world.This seems to contradict our most beloved verse in  the Bible, John 3:16, "For God so loved the world, that He gave His only Son, so that whoever believes in Him should not perish but have eternal life." So, it can make this text of ours so confusing. In light of all of this, it comes as a shock to the system when we read the words, "Do not love," and yet there they are, "Do not love." Even when I just let that sit there, you don’t like it. You are like, "finish the sentence." No, I want you to hear those words, "Do not love." It is a command, which means that if we violate it that we are in sin. In other words, love can be sinful. Remember, I told you this is an important word for our day, "Love can be sinful." We live in the midst of a culture that needs to hear that. It needs to hear that from us, because it is coming at us with this whole "Love is love" mentality, and how can you be against love?  Nobody can be against love. Certainly, Christians can't be against love, because God  is love and we are called to love. Therefore, how can you stand in the way of any two people who love one another? But our text today makes it very clear that there are instances when love can be sinful. In other words, this is more than just a theoretical theological discussion for us to have. This is a very practical rubber meets the road issue, this issue of love being sinful. The question is what makes  love sinful? What could possibly make love sinful? Under what circumstances would love be considered sinful?
Well, first of all, love becomes sinful when it is directed at the wrong object. Look at verse 15, "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." Do not love the world. Now, it is very important to note that this word "world, “ is used in  at least three different ways. First of all, the "world" can refer to all creation. You see this in John 1, John 3, John 4, John 6, John 7, John 8, over and over again.  This word "cosmos" refers to all the world, to all the created universe. John is not saying here that we should not love this universe, this world, this earth that God created. That is not what is being said here. Secondly, the term "world" refers to the people that inhabit this world that God created. And God is not saying, "Do not  love people. Do not love mankind." Absolutely not! We know that it doesn't mean that, because the love that we are called to give, even to our enemies, the great commandment: "Love the Lord your God with all your heart  and love your neighbor as yourself." So, John can't be talking about that first "world"  here, and he can't be talking about that second "world" here. That would be a contradiction.  However, there is a third use of the term "world" and that third use refers to the spiritual realm that is in opposition to God and in rebellion against His kingdom.  It is that third sense of "world" that is being discussed here. So, when John says,  "Do not love the world," he says your love becomes sinful when it is directed at that system that is anti-God, that system that is anti-kingdom, that system that is satanic. And he makes it obvious it is satanic because  he uses it several times here even in 1 John. John writes that by faith the Christian is able to overcome the world in 1 John 5:4 and 5. In our text he says the world passes away. In chapter 3 verse 1 he says the world is ignorant of God. In 3:13 he says the world hates believers. In  4:1 he says it is the abode of false prophets. In 4:3 it is the abode of the antichrist and in 4:5 it is the abode of unbelievers, and last, the whole world is controlled by the evil one. It is obvious here that when John refers to "world" in this text he is referring to that world that  is under the control of our adversary, the devil, that world that is spiritual and ideological  and at war with our King and His kingdom. And we are told, "Do not love that world." Not at all! Listen to Calvin. He had said before  that the only rule for living religiously is to love God, but as when we are occupied with the vain love of the world we turn away all our thoughts and affections another way. This vanity must first be torn away from us in order that the love of God may reign within us. Until our minds are cleansed, the former doctrine may be iterated a hundred times but with no effect. It will be like pouring water on a ball; you can gather, no, not a drop, because there is no empty place to retain the water. Like pouring water on a ball, when your  affections, when your love is pointed toward the world, there is no room for the  love of God, because when your love and your affections are pointed toward the world they are pointed toward that which opposes God; thus, love can become sinful when  it is directed at the wrong object. James says something similar in James  4 in verse 4, "You adulterous people! Do you not know that friendship with  the world is enmity with God? Therefore whoever wishes to be a friend of the world makes himself an enemy of God." "No man can serve two masters. He will love the  one and hate the other." This is an either/or situation. You cannot love the world and love God simultaneously. In fact, in our regeneration, in our salvation, we are taken out of the world. We are taken out of that system. We are brought out of darkness and into His marvelous light. We transfer kingdoms. We transfer allegiances, but if our love is still for the world our allegiance has not legitimately been transferred, which is why in 2:19, just after our passage,  John says, "They went out from among us, because they were not of us. If they had  been of us, they would have remained. But they left, so that it might be  known," so that it might be obvious, "that we might see that they were  never ours." They were never His, because their love, their affections were pointed at the system that is opposed to God. 1 John 5:4, "For everyone who has been born of God overcomes the world.   
And this is the victory that overcomes the world—our faith." John 15:19, "If you were of the world, the world would love you as its own; but because you are not of the world, but I chose you out of the world, therefore the world hates you." John 17:16, "They are not of the world, just as  I am not of the world." John 17:18, "As You sent me into the world, so I have sent them into the  world." Again, we've been sent into the world to proclaim the gospel, but we are not of this world. We are in this world, but not of this world, and we are most assuredly not to love this world.

A great way to see this picture is to think about the love that a man is commanded to have for  his wife. "Husbands, love your wives as Christ loved the church and gave Himself up for her." There is a love that husbands are called  to give exclusively to their wives, and the moment you turn that love onto  another you are guilty of idolatry.   
It is the same point here. The moment you turn that love that we are called to have for God, that love that has been shed abroad in our hearts, the minute you turn that to the world out of which you were saved, that minute you are communicating the fact that you do not have the love of God or love for God. Beloved, we must constantly examine our hearts for the presence of this love of the world. Now, be careful here, because there is a tendency to take this in very wrong directions. We have got to fight worldliness."Don't  participate in the world." He says, "Don't love the world." We must develop discernment in order to determine the difference, but not only that. Love becomes sinful when it arises from the wrong source, not only when it is pointed in the wrong direction, pointed toward the wrong object, but when it arises from the wrong source. Verse 16, "For all that is in the world—the  desires of the flesh, the desires of the eyes, the pride of life—is not from the  Father but is from the world." So there is a problem first with the object, and now here, there is a problem with the source. This love for the world arises from the world just like our love for God and for the things of God arises from God. It is God who gives us the capacity to love God, but here we have a love that is arising from a different source. The first two categories that are mentioned here, cravings and lust are sinful desires;  boasting, however, is sinful behavior: from internal to external. The first two are internal and hidden sins. The last one is revealed. The first two pertain to the individual person.   
The last one pertains to this person in community with others.Three categories: cravings, lust, and boasting. These things arise from the world; cravings, inordinate desires for things. And, again, we have to separate these. When we say cravings  and lust and boastings, we have to recognize that we are talking about this third "world"  and not the first two. For example, in that  first "world" I can love the beauty of a sunset,  I can love the beauty of music, art; again, those things in this world that God has made. I can and I must love the people whom God has created in this world, but the kind of love that I have for those things is a love that arises from God Himself but even those loves can be perverted, and  so now, instead of me loving the beauty of a sunset, all of a sudden, beauty of a sunset or a beauty of God's created order, now I worship God's created order. I worship the creature rather than the Creator. Rather than loving the beauty of those things that God has given us, now to quenching my lustful desires. That is when they have crossed a boundary. And then there are these boastings. That is when it gets outward. My cravings, my lust, and then my pride. those things become means to an end to satisfying myself, to gratifying my flesh, True love can lead me to share my testimony and pride can make me exaggerated. True love can cause me to use my voice  to proclaim the truth of the gospel. Pride makes me love the sound of my voice so that I just talk too much. True love can lead me to share my story, but my pride causes me to make myself the hero of every story I tell. It can make me one of those people who  constantly gives you their résumé. That is what it looks like when it becomes outward. True love can show gratitude for the things with which God has blessed me, but my pride can make me constantly give you the price tag of those things so that you can be impressed. So, our love can become sinful based on its direction and based on its source. But, finally, and ultimately, and most importantly, our love becomes sinful when it produces the wrong fruit, when it leads to the wrong ends. Look at verse 17. "And the world is passing away along with its desires, but whoever does the will of God abides forever." Here you have these two opposite ends. On the one hand you have this world that is passing away, and on the other hand you have our God who abides forever. Love becomes sinful when it leads to wrong ends and produces wrong fruit. Our passions become sinful when they are pointed  in directions that lead to death and destruction as opposed to leading to life. 1 Corinthians  7:29 to 31: "This is what I mean, brothers: the appointed time has grown very short. From now on, let those who have wives live as though they had none, and those who mourn as though they were not mourning, and those who rejoice as though they were not rejoicing, and those who buy as though they had no goods, and those who deal with the world as though they had no dealings with it. For the present form of this world is passing away."   
There is no life there.
And this leads us back to what I was mentioning earlier, the poignant way in which this is so pertinent to our times, because of the "love is love" crowd, particularly in the area of same-sex marriage.  How can you be opposed to same-sex marriage when same-sex marriage is just about people who love each other, being allowed to express that love? But that is a love that is pointed at the wrong object. That is not a love that comes from God.  Whether it brings glory and honor to God, it is pointed at the wrong object. It is a love that arises from the wrong source. Look with me if you will at Romans chapter 1, beginning at verse 18, familiar passage:   

"For the wrath of God is revealed  from heaven against all ungodliness   and the unrighteousness of men, who by their unrighteousness suppress the truth. For what can be known about God is plain to them, because God has shown it to them. For His invisible attributes, namely, His eternal power  and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse. For although they knew God, they did not honor Him as God or give thanks to Him, but they became futile in their thinking, and their foolish hearts were darkened. Claiming to be wise, they became fools, and exchanged the glory of the immortal God for images resembling mortal man and birds and animals and creeping things. Therefore God gave them up to the lusts of their hearts to impurity."  Here we are, these lusts, these desires, "to the dishonoring of their bodies among themselves, because they exchanged the truth about God for a lie and worshiped and served the creature rather than the Creator, who is blessed forever! Amen. For this reason God gave them up to dishonorable passions." Dishonorable passions; the desires themselves are dishonorable. Enough already with this gay Christian stuff! And I don't just say enough already; I don't mean this in the sense of, you know, "They're over there and I'm over here." I mean  this in the pastoral sense. How cruel is that! If a man comes to me talking about a desire for a woman who is not his wife, I am not one to tell him to just go ahead and embrace the desire, because the desire in and of itself is okay. It's not!   
"God gave them up to dishonorable passions. For their women exchanged the natural relations for those that are contrary to nature; and the  men likewise gave up natural relations with women and were consumed with passion for one another, men committing shameful acts with men and receiving in themselves the due penalty of their error." There is the bad fruit. It is pointed in the wrong direction.  It is arising from the wrong source, and it is producing bad fruit. Therefore, it falls into the category of love that is sinful. It falls into the category of love that does not glorify God. It falls into the category of love for that third version of the word "world;" not the first, "God's created order," not the second, "people in the world," but that third, that system that is openly opposed to all that God is and that rebels against the reign of God and His kingdom. And that is precisely where we are, brothers and sisters. And not only that, this rebellion is no longer covert, but it has become overt. It is out there and it is in our faces and, unfortunately, it is being urged along by people within the church, who are essentially arguing that love is always righteous, love is always godly, love is always appropriate, because God loves everyone and God loves everything; and right here, the Bible says, "Do not love."   
There are some loves that are out of bounds.There are some loves that aren't acceptable. In other words, there are some loves that are not truly love. And if you wrestle with that, let me say to you that the last thing you need to do is to give into that love and define yourself by it,  because that is love of the world.   
Do not love the world. Do not love based on your passions and your desires. But love the Lord your God with all your heart, all your soul, all your mind, and all your strength, which means your passions are to be turned in His direction and no other. We must reject the lie that says there is no love that is out of bounds, because ultimately that lie that says there is no love that is out of bounds is a lie that says there is no truth in God.
I am very well acquainted with the fact that love is not defined by allowing those whom you love to have what they want, when they want it, just because they want it. And we see that here in this text. Why? We'll end with this. Look at it again.   
"The world is passing away along with its desires, but whoever does the will of God abides forever." Do you see what is happening here? This, "Do  not love the world," is not God saying, "Listen, there is good stuff out there that I want to  keep from you." That is the lie of the serpent Satan. This "Do not love" says, "That looks good to you and may even feel good to you, but in the end you will perish. I am calling you away from it because I actually do love you and in loving you I want you to abide in God, to remain in God, and to not perish." Because our desire is that Christ indeed may have the fullness of the reward for which He died. So, do not love the world.
