Introduction
  Brief review of setting (MAP).  In most of Galatians, Paul argues for God’s grace and against  legalism. But in 4:12-20, he suddenly  shifts from theological argument to an extremely personal appeal (read). 
  This passage provides insight into Paul’s relationship with the  Galatians. The occasion of Paul’s first  visit was an illness—evidently a serious eye condition. He may have contracted malaria or opthalmia (chronic  eye infection) while he was in the coastal lowlands—so he evidently decided to  go into the highlands to get relief. His  eye condition was so unsightly that the Galatians could have been repelled, or  even could have concluded that he was under the judgment of the gods. But instead, Paul’s message of God’s grace  struck them so deeply that they honored and cared for him as the messenger of  God that he was. But now the Judaizers,  motivated by a selfish desire to gain a following, have slandered Paul’s  character to turn the Galatians against him.  Paul thus has to (from long distance) defend not only his message, but  also his character and motives toward them – for their spiritual welfare.
  This passage also provides insight (through Paul’s example) into  how Christians should relate to one another.  Notice the terms Paul uses to describe the Galatians – they are his  “brothers” (4:12) and “my dear children” (4:19). These are family terms, and they are connected to the previous passages we studied the last two  weeks.
  
    Read 4:5,6. God sent  Jesus to die for our sins so that He could adopt us as His sons/children. When you get adopted into God’s family, He  gives you His Spirit who enables you to relate to Him in a personal way, like a  child relating to his father who deeply loves him. But unlike child adoption in our culture,  which relies almost entirely on the adopting parents’ decision, we can and must  choose to respond to God’s adoptive initiative by personally receiving Christ  (read Jn.1:12). Have you made this  decision?
    This adoption also makes  us members of God’s new family (read 3:26,28).  God’s Spirit, who forges this bond with God when we become His children,  also forges a bond with other Christians so that we become brothers and  sisters. Now what? Now we are to mature in God’s family – to help one another to develop into  spiritual adults – people who are increasingly Christ-like in character and  values. 
    
      Paul felt this responsibility toward the Galatians as his  brethren and spiritual children, and toward all of the Christians to whom he  related (read Col.1:28). 
      But this is not just the responsibility of Christian leaders;  it is a responsibility that we all have toward one another (read Eph.4:14a,15,16). Just as every member in a physical body must  participate for that body to grow and mature, so each of us must participate in  the family of God if we are to grow and mature.  If you have received Christ, the question is not: “Do you belong to God’s  family?” (You do, forever), but rather: Will  you be vitally involved in God’s family, or will you be an isolated spiritual  consumer? It is difficult to  exaggerate how important this decision is.  It will have a huge impact on you, on your marriage and children, on  other Christian brothers and sisters, and on people who don’t yet know Christ.
    
    This church is committed to help you mature in God’s  family. This is why we are not a  large-meeting church that has home groups, but that we are a home group-based  church that also has large meetings. Why? Because the family of God can become a personal  reality only in such communities. Do you  come here once a week to consume spiritual food, and then live the rest of the  week isolated from your brothers and sisters?  Or are have you committed yourself to a smaller family of brothers and  sisters to help one another mature?  (EXPLAIN HOW TO GET IN A HOME GROUP)
    Let’s say that you have decided to become a responsible family  member and have joined a home group. How  can we help one another mature spiritually in this context? Paul models two key ways to do this...
  
Personal investment & vulnerability
  This paragraph demonstrates Paul’s personal investment and vulnerability with the Galatian  Christians. You can see this most  clearly in 4:19 (read), where Paul calls them “my children” and refers to his  past and present motherly concern for their spiritual well-being. This is probably what he referring to in 4:12a  (read). Literally, Paul says: “I beg of  you, brethren, be like me, as I (have become) like you.” He seems to be appealing to the Galatians to  reciprocate the warmth and affection he has always had toward them.  He expressed a similar request to the  Corinthians when they were estranged from him (2Cor.6:11,13). Paul’s involvement with converts was not only  biblical instruction; he got involved with them enough that he was affected  emotionally by their spiritual welfare.  He rejoiced when they flourished spiritually, and he became agonized  when they were in peril.
  
    Paul describes his relationship with the Thessalonian  Christians along these same lines (read 1 Thess.2:7,8). Like a mother, he expressed his affection for  them and gave himself to them. (When I  read these passages the first time, I was embarrassed for Paul. Now I am embarrassed for me!) 
    I don’t think that this came naturally to Paul – he was by  nature a highly functional and self-sufficient person, not empathetic and  affectionate and emotionally vulnerable.  He had to decide to let God teach  him to relate to people in this way, because he knew it was essential to  helping others mature in Christ. And he  let others relate to him in this way for the same reason. 
  
  And what Paul learned, we can learn. That’s why he prescribes Rom.12:10,15  (read NLT). As members of God’s family,  we don’t have to wait until we feel affection to invest; we can choose to  invest until we feel real affection. We  don’t have to wait until we feel emotionally affected by their good or ill  condition to express empathy; we can choose to express empathy, and we will  eventually come to feel it more. We  don’t have to wait until we feel comfortable being vulnerable to Christian  friends (weaknesses, fears, dreams, disappointments, doubts, etc.); we can  choose to do this until it feels helpful.
  I hear three common objections to this mandate, and they are  formidable – but God can help us to overcome each one of them.
  
    “I don’t have enough in common with these people.” “In common” means natural affinity (i.e., age,  background, marital status, hobby interest, etc.). This is a bonus, not a requirement. We have the most important thing in common  (Jesus), so we should invest in the brothers and sisters God has put into our  lives. When we do this, we find that  although we would not naturally know (or have wanted to know) one another apart  from Christ, we have built a deeper unity with them that demonstrates the  reality of Jesus in our midst (OUR HOME CHURCH).
    “I don’t have time for this.”  It definitely takes time to do this – time to meet together in various  contexts (CT; home group; cell group; one-on-one). Some things will definitely have to be  reduced or sacrificed (TV series/movies; shopping; hobbies). But God will give us the time for this of we  ask Him. And there is a richness in this  way of life that far surpasses a life of entertainment or “playing church.” And this kind of investment is what enables  us to be effective at home and at work.
    “I don’t want to get hurt again.” Many of us have been hurt in dysfunctional  families, and vowed to ourselves to never let anyone get close enough to hurt  us again. Some of us have been hurt by  Christian friends (disappointed, unfairly criticized, even betrayed). I’ve been hurt by doing this before. But we have God’s sufficient and reliable love  available to us now. And when we decide  to open our hearts to others, somehow this opens our hearts to experience more  of God’s love – which gradually heals our hurts. Besides, self-protectiveness exacts a terrible  price. 
  
  So if we are willing to trust God’s wisdom and provision, we  can overcome these objections and embrace this kind of personal investment as a  way of life. If you do this, you will eventually  need to learn the second key Paul models in this passage...
Engagement in constructive conflict
  Read 4:16,17. Paul is willing  to engage in constructive conflict with the Galatians. This whole letter is  Paul doing this – correcting them and warning them to turn away from the  Judaizers’ teaching back to God’s truth.  Here, he is saying: “Why are you pushing me away because I correct you  with God’s Word? Don’t follow those guys—they  don’t really care about you, they just want to use you.” Paul had faithfully served the Galatians – yet  they were criticizing him and accusing him of being an unprincipled man-pleaser. He could have gone ballistic. He could have simply said: “I don’t need  this—I’ve got lots of other people who respect me and want to hear what I  say.” Yet he moved toward them and  risked more hurt and rejection because he was more committed to their maturity  than he was to his relational comfort.  He was willing to have conflict with them because they were headed down  a path that would hurt them. He couldn’t  stop them from going down that path, but he had to try to warn them for their  good. Paul did this when needed in all  of his Christian relationships (see Acts 20:20a,31b).
  But it isn’t just leaders’ job to do this – we all need to engage in constructive  conflict with one another when necessary.  Jesus commands us to reprove one another when we’re in sin  (Matt.18:15,16). Paul tells us to  admonish (warn; correct) one another with God’s Word (Col.3:16). We all go astray at times, we all get blind and  stubborn, so we all need brothers and sisters who will fight for us by fighting with us in this way.
  
    I owe so much to the brothers and sisters who have loved me enough  to do this! I hate to think where I  would be today if they hadn’t done this.  My character flaws would have ruined my life and dishonored Christ. I likely would have lost my marriage and  alienated all kinds of people because of my arrogance. I would not have fulfilled even a fraction of  my potential for serving Christ.
    Unwillingness to engage in constructive conflict is all it  takes to kill a home group. A silent  “Don’t ask; don’t tell” conspiracy develops.  Healthy closeness becomes impossible.  Instead of maturing, people get stuck in their sins and drown because no  one cared enough to try to rescue them.
  
  We need more home group members who are willing to do  this. What holds you back from this key aspect  of Christian family life? 
  
    “I’m not involved enough with others to see when this is  needed.” Then focus on the first key for  now.
    “I feel incompetent to do this.” Learn the biblical principles involved (Loving God’s Way: “Admonish One Another”). Ask for advice. If you are willing to wade in there, God will  show you the step you need to take. Better  to make a mistake trying and apologize than not to try.
    “I fear losing the relationship over this.” God will never reject you, and He will uphold  you as you do this. And although some of  your relationships may end over this, many of them will get better and deeper  because of this. 
    “I don’t want the discomfort that this will cause me.” The loneliness of isolation brings its own  debilitating discomfort. God will  empower and bless you as you repent from this, which is far better than no  discomfort!
  
Conclusion
  Don’t settle for perpetual  immaturity through spiritual consumerism!  Take the step God is showing you to mature in His family. He will enrich your life in ways you never  thought were possible!
SUMMARIZE: Let’s discuss further how we can help one another  mature in God’s family.
  “He may simply mean, ‘Be...  as loving with me as I have always been with you.’ Either way, it is clearly a  personal appeal to the Galatians to resume their old friendly relations with  Paul which have apparently been ruptured by the work of the Judaizers.” Cole, R. A. (1989). Galatians: an introduction and commentary (Vol. 9, p. 167). Downers  Grove, IL: InterVarsity Press. “I beg of  you, brethren...” likewise expresses affectionate pleading. 
  “To love  at all is to be vulnerable. Love anything, and your heart will certainly  be wrung and possibly broken. If you want to make sure of keeping it  intact, you must give your heart to no one, not even to an animal. Wrap  it careful round with hobbies and little luxuries; avoid all entanglements;  lock it up safe in the casket or coffin of your selfishness. But in that  casket – safe, dark, motionless, airless – it will change. It will not be  broken; it will become unbreakable, impenetrable, irredeemable. The only  place outside of Heaven where you can be perfectly safe from the dangers of  love . . . is Hell.” C.S. Lewis, The Four Loves.
