Introduction
Reiterate the biblical change model. In chapter 7, Paul is urging the single Corinthian  Christians to consider staying single.  But he doesn’t simply lay down rules.  Instead, he enunciates a principle of WOG pertaining to major life  decisions—(read 7:17-24).
Paul states the principle three times (7:17,20,24). He says he teaches it in all the churches  (7:17). The first thing we need is to  understand what this principle is.
The principle: “Grow where you’re planted”
Paul tells these adult converts that God was sovereignly  involved in the life situations in which they became Christians, and that God  is with them in that life situation (7:24).  Since this is the case, they should in general assume that they are to  walk with (7:17) and grow in Christ in that same life situation. “Grow where you’re planted.” This the opposite of a restless, “the grass  is always greener on the other side of the hill” attitude.
Like all biblical principles, this principle has both wide  application and exceptions:
  Paul applies it not only to celibacy, but also to  ethnic-cultural identity (circumcision was a key marker for Jewish identity;  uncircumcision was a key marker for Gentile identity), and to socio-economic  status (slave/free).  It would apply to other major life decisions like  getting divorced, career changes, church involvement changes, residence  changes, etc.
  On the other hand, biblical principles are not moral absolutes  (like sexual purity, for example). There  are legitimate exceptions to biblical principles—and you can see Paul  acknowledging and even advising exceptions in this chapter and letter.
  
    It is good to stay unmarried—but it is not wrong to marry  (7:27b,28a), and marriage is even preferable if you aren’t gifted for celibacy  (7:7).
    It is OK to stay a slave—but it is good to become free if you  can (7:21b), and not good to become a slave if you can stay free (7:23).
    It is good to retain your cultural identity—but there are times  when it is good to intentionally change your cultural identity (9:19-21; Acts  16:3).
    So also, there are biblical exceptions to this principle with divorce  (e.g., because of infidelity; abuse) career change (e.g., in order to provide  for your family), church involvement change (e.g., because of spiritual  deadness or apostasy), and residence change (e.g., to flee persecution; to  plant a church/do missions).
  
What’s the use of a biblical principle like this if there  are exceptions to it? And how can you  know when to follow this principle or make an exception to it? (This is why legalists like rules and hate  principles.) The key is to understand  the wisdom that undergirds this principle...
The wisdom that undergirds “Grow where you’re planted”
It should be obvious that the WOW does not subscribe to this principle.  Its wisdom in this areas is: “The better my life circumstances are, the  happier I will be.” It is self-centered,  so it assumes that our personal happiness is the primary goal of our lives. Second, it assumes that life circumstances  are the key to personal happiness. (Even  the word “happiness” has the same root as “happen” or “happenstance.”)
  If you accept these two assumptions, the right to change your  life circumstances becomes one of the most important things in your life. This is a central part of the “American  Dream”—not just that it is good to have the freedom to make such changes (TRUE),  but that this is critical in our “pursuit of happiness” (FALSE).
  This is why those who subscribe to WOW dislike this principle. What is your reaction to this principle? What does  this tell you about your operational wisdom?
The WOG says: “I can become more Christ-like and serve God and  others regardless of my life circumstances.”  It is God-centered and self-giving, so it assumes that the primary goal of  our lives is to become more Christ-like and serve. (It regards personal happiness not as the  goal of life, but as a nice by-product of the goal.) It is God-centered also in its assumption  that God is sovereign over our life circumstances. This doesn’t mean that every circumstance in  our lives was designed by God; it means that God can work within every life  circumstance to accomplish His purpose for our lives.
  This is Paul’s point in 7:19.  Since what counts is keeping God’s commandments (love God &  neighbor), I can do this whether I am culturally Jewish or Gentile. So also in 7:21,22. What counts is being a servant of Christ—and I  am free serve Christ even if I’m a slave, and Christ calls me to serve Him even  if I’m a freedman.
How can we know which wisdom is right? Jesus told us of one way when He said:  “Wisdom is vindicated by her children” (Matt.11:19). We can know confirm God’s wisdom by seeing the  long-term reward it brings to those who have followed it. 
  There is abundant evidence that this element of WOG rewards its  “children”:
  
    Paul himself is part of that evidence. Some years after he wrote 1 Corinthians, he  was unjustly imprisoned for four long years.  His circumstances were unpleasant, and he couldn’t change them. The WOW would say that Paul was doomed to  misery. But he operated by the WOG, and  he describes its rich reward in Phil.4:11-13 (read). Paul was content regardless of his circumstances  because he lived to serve Christ—and he had learned that Christ would  strengthen him to do all that He wanted Paul to do. This is why this letter is known as the “joy  epistle.”
    Talk to people in this church who have walked with Christ for  many years. They will tell you about  many life-situation changes they could have made, but didn’t because they  didn’t think they would advance their goal—to become more Christ-like and serve  God more effectively. But they will also  tell you that they do not regret these sacrifices, because the satisfaction of  spiritual maturity and fruitfulness more than makes up for it.
  
  There is also abundant evidence  that this element of WOW betrays its “children”:
  
    Those who prioritize higher income do so because they believe  that more money will enable them to have more power to change their  circumstances—which will make them more happy.  But they are in fact usually unhappier than those who stay at the same  income level. 
    Those who divorce because of their unhappiness happiness are statistically  far more likely to divorce again, and again.
    Those who change friends to avoid relational difficulties tend  to be dissatisfied with their new friendships (“Good friends are hard to  find”).
    Those who change churches because they “didn’t meet my needs”  tend to never find a church that really satisfies them.
  
  I saw this lived out by my own parents. My father loved me and helped me in many  ways—but he subscribed to this element of WOW.  He avoided many family responsibilities in order to play. He complained about his job and retired as  soon as he inherited his father’s money.  He spent the last 35 years of his life doing what he wanted to do. And he was pretty chronically unhappy (though  he came to Christ not long before he died!).  My mother, on the other hand, subscribed to WOG. She came to Christ when my handicapped sister  was born, and decided to trust Him for the strength to be a servant. So she stayed in a difficult marriage. She embraced the responsibility of caring for  her daughter while raising two other children.  She worked as a seamstress to offset  my father’s financial irresponsibility.  She learned to be a thankful servant, and is one of the most content  people I have ever known. 
What about you? Which  outcome do you want? Don’t you see that  the outcome flows from which wisdom you embrace? Read Jn.10:10,11. The WOW will eat you up and spit you out  because its leader (Satan) is a thief.  He doesn’t care about you; he comes only to steal and kill and destroy. But Jesus Christ is the Good Shepherd. He is God’s wisdom, so He can lead you down  its path. And you can trust Him because He  laid His life down for you. Turn away  from WOW and give yourself to the Good Shepherd by asking Him to forgive you of  your sins and indwell you with His Spirit.  You will never regret this decision!
Applying “Grow where you’re planted” to major life decisions
Once you entrust yourself to Christ, you need to learn when  to apply this principle to major life decisions. There is no formula for when you should  follow it and when to make an exception.  But here are three key questions that will help you do this.
  “What have I learned from God through the circumstances I want  to change?” God has been sovereignly  working in your present circumstance (especially through the difficulties) to  mature you (Jas.1:2-4). Can you  say that you have substantially learned these lessons, or have you ignored or  rejected them?” You will take you with  you wherever you go! 
  
    JOB: There are many valid reasons for changing jobs. But there are also invalid reasons. Maybe your boss is difficult—but do you have  a problem respecting and submitting to authority? Maybe your job is rigorous—but do you have a  problem with working hard? These are character  issues that will affect your job satisfaction and your witness for Christ wherever  you work. Maybe should you make progress  in these before you change jobs.
    CHURCH INVOLVEMENT: There are unhealthy churches that wise  people leave. But much more often I see  Christians “move on” because people called on them to be transparent and/or to  serve, or because of interpersonal conflict.  God is working through these challenges to teach you humility and  forgiveness and servanthood. Maybe you  should change what you seek in church instead of seeking to change churches.
  
  “Why do I want to make a change in this area of my life?” Is it primarily to escape circumstances you  don’t like, or to get circumstances you think will make you happy? Or is it to better pursue spiritual growth  and service for God? Your reasons will  reveal your true values—and your true values will reveal which wisdom you are  following.
  
    GEOGRAPHICAL MOVE: There is nothing intrinsically wrong with  moving, but why are you moving? “Because  I've always planned to, I hate Columbus’ flatness and weather, the job market  is better, etc.” What about other more  important considerations? Do you know  you will have as good or better opportunity for spiritual growth, equipping,  and service? “I can get more house for  the money.” But what will this cost you  and your family if you both have to work full-time? What if it makes real involvement with  Christian friends more difficult? Maybe  you should consider staying where you are and living more simply.
    MARRIAGE: Unless you are gifted with celibacy, it is good to  seek marriage. But not simply to escape  being single, or even because you feel “in love.” Are you both a committed Christians? Are you are able to help each other grow in  Christ-like character—including giving and receiving correction? Have you seen evidence that you can serve God  better together than apart? Maybe you  should wait.
  
  “Have I sought godly counsel  about this decision?” If not, why  not? Is it because you are  over-confident about your wisdom? If so,  have you sought godly, wise counsel—or only people you think will agree with you? I cannot stress enough how important it is to  commit yourself to a group of Christian friends who are committed to helping  one another live according to the WOW (PROMOTE HOME GROUPS)!
Conclusion
Read 7:35. This is the  spirit in which I teach you this principle, remind you of the WOG that  undergirds it, and urge you to ask these questions. The WOW tells you that this principle will  restrict you and make you miserable, but undistracted devotion to the Lord will  always be for your own ultimate benefit! 
  It was  possible to become uncircumcised by undergoing a surgery, and it was possible  for slaves to earn their freedom by saving and paying the price of their  manumission.
  “Vast  numbers of us have been seduced into believing that having more wealth and  material possessions is essential to the good life... (But  Kasser’s) formidable body of research highlights what for most of us is a quite  counter-intuitive fact: even when people obtain more money and material goods,  they do not become more satisfied with their lives, or more psychologically  healthy because of it. More  specifically, once people are above poverty levels of income, gains in wealth  have little to no incremental payoff in terms of happiness or well-being. (Moreover) merely aspiring to have greater wealth or more material possessions is  likely to be associated with increased personal  unhappiness... People with strong materialistic values and  desires report more symptoms of anxiety, are at greater risk for depression...  use more alcohol and drugs, and have more impoverished personal  relationships... Thus, insofar as people have adopted the  ‘American dream’ of stuffing their pockets, they seem to that extent to be  emptier of self and soul.” Richard M. Ryan in Tim Kasser, The High Price of Materialism (Cambridge, Massachusetts:  The MIT Press, 2002), pp.x,xi.
