God Grant Us a Growing Faith!

1 Corinthians 3:1-9 Paul once said about his own life of faith:  When I was a child, I spoke like a child, I thought like a child, I reasoned like a child. When I became a man, I gave up childish ways.   God expects the same of us-- that we would “grow up” spiritually into the mature sons and daughters that he created us, redeemed us, and sanctified us to be. 

Over the course of our lives, God wants us to become more mature in our Christian faith—more mature in our Christian worldview—more mature in our Christian life.  That’s what we’re going to talk about today:  what spiritual immaturity is- what undermines our spiritual growth -and how we can “grow up” spiritually into mature believer in Christ.  Paul writes:

Brothers, I could not address you as spiritual people, but as people of the flesh, as infants in Christ.  I fed you with milk, not solid food, for you were not ready for it. And even now you are not yet ready…

When someone tells us to “grow up” it’s difficult to hear that in any other way than as an insult—and we quickly get defensive.  That’s why I want you to focus on that one little word that begins our text and let is inform us as to how we are to hear these words to “grow up”—and that is the word “brother.” 

Paul addressed the Corinthian Christians—and he addresses the San Angelo Christians—as brothers and sisters in Christ—members of the same household of faith—children of the same heavenly Father.  And so God’s command through Paul to “grow up”-- is spoken out of genuine love and concern for our spiritual well-being—that there would be growth and progress and maturity in our spiritual life.

When people in Corinth began coming to faith in Jesus and then joined together in a Christian congregation—they were infants in the faith—they were newly re-born believers in Jesus—just beginning to learn what it meant to be children of God.    

And so Paul taught them simply:  he told them about their sin and need for God—he told them about the Savior God had given in Christ—he told them how the Spirit had worked to bring them to life.  It’s the same thing we do in Sunday School & confirmation & new member classes.  And through the word of the cross we became children of God.

Five years had passed from the founding of that congregation to this letter—five years from when they came to faith in Jesus-- to where they found themselves spiritually when they received this letter.  The problem was:  they hadn’t progressed much at all in those five years—they were still infants in the faith—they hadn’t grown up or matured.

When it comes our children’s physical growth and maturation—five years is a phenomenal amount of time—a newborn baby that is absolutely helpless, incapable of communication, and barely aware its surroundings, five years later has become a little boy with lunch box heading off to the first day of school.  Fantastic progress and growth!

But those five years between the Corinthians being born again- and the occasion of this letter- had not yielded five years worth of spiritual growth and maturity.  Yes, they were saved—yes, they were Christians—but they hadn’t grown up in their faith.

What about us?  What positive changes have the last five years brought in our life of faith?  Do we have a deeper knowledge of the things of God?  Have we grown in Christ-likeness?  Are we more spiritually mature today than we were back then? 

That’s what our heavenly Father wants to see in his children.  That’s why these words from Paul about the need to “grow up” spiritually-- are spoken to us too. 

And so what was the problem that was impeding the Corinthian’s growth in the faith?  What is it that keeps us from becoming mature Christians?  Paul writes:

You are still of the flesh. For while there is jealousy and strife among you, are you not of the flesh and behaving only in a human way? For when one says, “I follow Paul,” and another, “I follow Apollos,” are you not being merely human? 

            In our previous sermons on these opening chapters of First Corinthians we talked about how there was division in the congregation stemming from their individual attachments to some pastor who had served them—how, what should have been a harmless preference-- had turned into a hurtful problem in that place. 

In their hearts, they were jealous of one another.  Each wanted the prestige that came from being attached to some great pastor.  And this attitude showed up in how they treated one another—fussing and fighting and failing to get along.  Jealousy and strife was the sinful attitude and behavior—but what was at the root of it went much deeper.

            The Corinthians were living according to the flesh.  In other words, they were living like the unbelieving world around them—living according to their old, sinful nature-- living as if they had never come to faith at all. 

The new person that they were through faith in Jesus was nowhere to be seen.  What about us?  It doesn’t have to be strife or jealousy or divisiveness that reveals an immature Christian faith. 

 Anytime some facet of our lives looks like the unbelieving world rather than Jesus—anytime our actions and attitudes are guided by our flesh rather than the Spirit—there is a lack of spiritual maturity in that part of our lives and we need to grow up.  And so how does that happen—this spiritual growth that God is looking for in us?  Paul says:

What then is Apollos? What is Paul? Servants through whom you believed, as the Lord assigned to each. I planted, Apollos watered, but God gave the growth.  So neither he who plants nor he who waters is anything, but only God who gives the growth. He who plants and he who waters are one, and each will receive his wages according to his labor.

            The solution to growing up spiritually begins with knowledge--that we know and understand what God’s will is for our lives-- and what he teaches about each part of our lives as his people.  We don’t chastise kindergartners for only knowing their A, B, C’s but neither are we content that they possess only that knowledge when they get to fifth grade.  They should have matured in the things they know and their ability to do them.  Their knowledge ought to have expanded. 

That’s what Paul was doing for the Corinthians in these verses.  He told them that, not only was their thinking about the pastors who have served them incorrect and sinful, he also explained how they ought to think about their pastors—that pastors were merely servants who did the thing that needed to be done for the people of God in that moment. 

The same process is needed if there is some facet of our lives that has not attained spiritual maturity.  We need to learn what God wants from us and what he forbids to us.  We need to search God’s Word for what our heavenly Father has to say and order our lives accordingly.  But to do that—we need God’s help. 

Our heavenly Father is the One who caused us to be born again and he is the One who helps us grow up in our faith to reach spiritual maturity.  Paul writes:  For we are God's fellow workers. You are God's field, God's building.

            Earlier in the sermon I mentioned how important it was that we hear this call to “grow up” spoken in the context of that word “brother”—that Paul has our best interests at heart when he tells us to “grow up”.  I hope these closing words will provide the same comfort—even if you are an infant in Christ. 

When we look back at the last five years of our lives of faith, maybe we don’t see a lot of spiritual growth—maybe we haven’t become more Christ-like—maybe our knowledge of the things of God hasn’t really deepened all that much-maybe we are not the spiritually mature Christians we ought to be by now. It’s easy to become discouraged. 

But Paul reminds us:  We are God’s field.  We are God’s building.  In other words, the God who saved us by the blood of his Son hasn’t given up on us anymore than we give up on our children when we are teaching them to tie their shoes or ride a bike. 

Like a farmer plowing a field or a craftsman constructing a building—God is at work in us.  He knows what he is looking for in us and so he patiently works through pastors (his fellow workers) to shape us into a finished product:  the mature Christian who is fruitful in good works and whose life is beautiful monument to the glory of God and the goodness of Christ.

When we listen to God’s Word and study the Bible in Sunday School and receive the Sacrament of the Altar—there in those moments-- and through that man-- and by those humble means—God is at work in us, helping us to grow up in our faith in Jesus. 

And God wants us to put that faith into practice.  It’s fun watching our kids learn to walk.  There are a lot of bumps and bruises but they don’t give up and eventually they leave crawling behind.  So it must be for us when it comes to stepping out in faith, putting away childish things, and growing up in our faith.

Most of us have seen the bumper sticker:  “Be patient—God’s not finished with me yet” and usually we can add our hearty “Amen!  You need more work!”  But the good news is that slogan is true of us too. 

We’re not as mature a Christian as we ought to be.  We haven’t grown up into all that God wants us to be.  But the Lord’s not finished with us yet and he will help us to grow up in our faith as we hear his Word and receive the sacrament.  Amen.
