FIVE REASONS WHY YOUNG CHRISTIANS OFTEN NEGLECT PERSONAL HOLINESS by Kevin DeYoung
I have a growing concern that younger evangelicals do not take seriously the Bible’s call to personal holiness. We are too at peace with worldliness in our homes, too at ease with sin in our lives, too content with spiritual immaturity in our churches.
FIVE REASONS WHY YOUNG CHRISTIANS OFTEN NEGLECT PERSONAL HOLINESS by Kevin DeYoung
I have a growing concern that younger evangelicals do not take seriously the Bible’s call to personal holiness. We are too at peace with worldliness in our homes, too at ease with sin in our lives, too content with spiritual immaturity in our churches.
  God’s mission in the world is to save a people and sanctify  his people. Christ died “that those who live might no longer live for  themselves but for him who for their sake died and was raised.” (2 Cor.  5:15) We were chosen in Christ “before the foundation of the world, that  we should be holy and blameless before him.” (Eph. 1:4) Christ “loved  the church and gave himself up for her, that he might sanctify her…so  that he might present the church to himself in splendor, without spot or  wrinkle or any such thing, that she might be holy and without blemish.”  (Eph. 5:25-27) Christ “gave himself for us to redeem us from all  lawlessness and purify for himself a people for his own possession who  are zealous for good works.” (Titus 2:14)
  J.C. Ryle, the Bishop of Liverpool from the nineteenth century, was right: “We must be holy, because this is one grand end and purpose  for which Christ came into the world…Jesus is a complete Savior. He  does not merely take away the guilt of a believer’s sin, He does more—He  breaks its power (1 Pet. 1:2; Rom. 8:29; Eph. 1:4; 2 Tim. 1:9; Heb.  12:10).” My fear is that as we rightly celebrate, and in some quarters  rediscover, all that Christ saved us from, we will give little thought and make little effort concerning all that Christ saved us to.
  The pursuit of holiness does not occupy the place in our hearts that it  should. There are several reasons for the relative neglect of personal  holiness.
1) It was too common in the past to equate holiness  with abstaining from a few taboo practices like drinking, smoking, and  dancing. In a previous generation, godliness meant you didn’t do these  things. Younger generations have little patience for these sorts of  rules. They either don’t agree with the rules, or they figure they’ve  got those bases covered so there’s not much else to worry about.
2) Related to the first reason is the fear that a  passion for holiness makes you some kind of weird holdover from a bygone  era. As soon as you talk about swearing or movies or music or modesty  or sexual purity or self-control or just plain godliness, people get  nervous that others will call them legalistic, or worse, a  fundamentalist.
3) We live in a culture of cool, and to be cool means  you differentiate yourself from others. That has often meant pushing the  boundaries with language, with entertainment, with alcohol, and with  fashion. Of course, holiness is much more than these things, but in an  effort to be hip, many Christians have figured holiness has nothing to do with these things. They’ve willingly embraced Christian freedom, but they’ve not earnestly pursued Christian virtue.
4) Among more liberal Christians, a radical pursuit of  holiness is often suspect because any talk of right and wrong behaviors  feels judgmental and intolerant. If we are to be “without spot or  blemish,” it necessitates we distinguish between what sort of attitudes,  actions, and habits are pure and what sort are impure. This sort of  sorting gets you in trouble with the pluralism police.
5) Among conservative Christians, there is sometimes  the mistaken notion that if we are truly gospel-centered, we won’t talk  about rules or imperatives or exhort Christians to moral exertion. To be  sure, there is a rash of moralistic teaching out there, but sometimes  we go to the other extreme and act as if the Bible shouldn’t advise our  morals at all. We are so eager not to confuse indicatives and  imperatives (a point I’ve made many times) that if we’re not careful,  we’ll drop the imperatives altogether. We’ve been afraid of words like  diligence, effort, and obedience. We’ve downplayed verses that call us  to work out our salvation with fear and trembling (Phil. 2:12) or  command us to cleanse ourselves from every defilement of body and spirit  (2 Cor. 7:1) or warn against even a hint of immorality among the saints  (Eph. 5:3).
  I find it telling that you can find plenty of young Christians today  who are really excited about justice and serving in their communities. 
You can find Christians fired up about evangelism. You can find lots of Generation XYZ believers passionate about precise theology. Yes and amen to all that. But where are the Christians known for their zeal for holiness? Where is the corresponding passion for honoring Christ with Christlike obedience? We need more Christian leaders on our campuses, in our cities, in our seminaries who will say with Paul, “Look carefully then how you walk.” (Eph. 5:15)

  When is the last time we took a verse like Ephesians 5:4—“Let there be  no filthiness nor foolish talk nor crude joking, which are out of place,  but instead let there be thanksgiving”—when is the last time we took a  verse like this and even began to try to apply this to our conversation,  our joking, our movies, our YouTube clips, our TV and commercial  intake? The fact of the matter is if you read through the New Testament  epistles, you will find very few explicit commands that tell us to  evangelize and very few explicit commands that tell us to take care of  the poor in our communities, but there are dozens and dozens of verses  in the New Testament that enjoin us, in one way or another, to be holy  as God is holy (e.g., 1 Peter 1:13-16).
  I do not wish to denigrate any of the other biblical emphases capturing  the attention of younger evangelicals. But I believe God would have us  be much more careful with our eyes, our ears, and our mouth. It’s not  pietism, legalism, or fundamentalism to take holiness seriously. It’s  the way of all those who have been called to a holy calling by a holy  God.
