Discipleship - Growing in Grace and Truth (Rev. Erik Veerman)

Sep 21, 2025    Erik Veerman

Over the last 6 weeks, we’ve been talking through our vision, mission, and philosophy as a church. We started with 4 sermons on the pillars to our ministry.


·   First, being a faithful church, which begins with God’s faithfulness to us in the Gospel.

·   Second, the means through which God applies his grace in us – which are his Word, prayer, and the sacraments.

·   Third, the overarching theme of the entire Bible, God’s covenant promises and their fulfillment in Christ.

·   And forth, God’s appointed leaders for his church – elders.


And now we are applying those pillars to our worship, our discipleship, and our missions. Last week we focused on worship – that is, corporate worship. This week’s focus is on discipleship, and then next week, we will conclude with missions and outreach.


Please turn to Matthew 28 in your Bibles. Our first of two sermon texts is what we call the great commission. Matthew 28:18-20. That is on page 993 in the Pew Bible.


You may be wondering why our sermon text is the great commission, yet our focus is on discipleship. Well, that is because this passage is about discipleship. You can’t really separate missions and discipleship. In fact, worship is in the mix as well. Discipleship begins in worship and includes missions. They all overlap.


Reading of Matthew 28:18-20


Our second sermon text is from 2 Peter chapter 3. That is on page 1209 in the Pew Bible. 2 Peter 3 verses 14-18.


This is one of the more traditional passages related to discipleship. The apostle Peter has just written about the second coming of Christ. And then Peter writes these very important words as far as our godliness and our knowledge of Jesus Christ, as we wait for the new heavens and hearth.


Reading of 2 Peter 3:14-18


Prayer


If you were to survey 1000 pastors and you were to ask each one for a definition of discipleship, you would get 1000 different answers.


Some would focus on relationships. Others would focus on Bible study. Some would center their answer on serving. Others would say it’s about being real. Others would make the case that discipleship is all about missions. Some would say that it is about God’s kingdom – kingdom discipleship. For others, it’s life-on-life ministry. Others talk about sonship – being sons of God. Yet others describe it as head, heart, and hands. For some, families are the most important thing. For others, the church is key. Some say discipleship is about self-denial and taking up your cross.


And we ask why? Why are there a gazillion definitions of discipleship?


Well, I think the main part of the answer is quite simple.


The word “discipleship” is not in the Bible. It is therefore difficult to come up with a Biblical definition for that reason. To be sure, the word “disciple” singular and “disciples” plural are in the Bible. It’s just that the word discipleship is not. It’s is a word that we’ve come up with to capture the task of making disciples. The word discipleship seeks to answer the “how” questions. How do we make disciples of Jesus? Discipleship is about implementation. That is why there are so many definitions.


And so, I think it’s better not to come up with a single approach to discipleship. Rather, I think it’s best to first understand what a disciple is, then second, consider the foundations to making disciples. And only after we do that, can we evaluate discipleship approaches and start identifying our own principles.


Here’s what I am saying… rather than trying to come up with a definition of discipleship, it’s better to consider the broader Biblical framework for the task of making disciples. That framework can then be used to evaluate discipleship approaches.


By the way, this is an impossible task. I’m not talking about identifying the Biblical principles for making disciples, I’m talking about trying to preach on it in one sermon. I realized this on Friday afternoon. I thought, what have I got myself into? There is no way to fit this into a 30+ minute sermon. I also thought, I’m looking forward to getting back to our regular expository sermons in a couple of weeks.


But we are here now. And many of you have mentioned that this series has been helpful. So, I’m going to press on and try.


1. What is a disciple and what is the call?


As I mentioned, let’s begin with the question, what is a disciple?


Let’s start by looking at Matthew 28. These verses give us a good foundation on what a disciple is and what a disciple should pursue. And we know these verses well. Matthew 28 verse 19 – “Go therefore and make disciples.” By the way, much debate has been had about the underlying Greek words, especially the word “go.” We’re not going to “go” there today. Let me simply say that the imperative here is to “make disciples.”


The call is to bring people from not following Jesus to following Jesus. That is what the word disciple means - a follower. Being a follower includes, of course, believing in Jesus, but it implies a lot more. It includes a commitment to Jesus’ teaching, and his ways, and pursuing his commands… just like Jesus’ 12 disciples did.


So the call in Matthew 28 is to “make disciples” and that involves two things here. First, it’s bringing them into the covenant community. That’s what Baptism is. It includes either being part of a household, like circumcision in the Old Testament – that’s one reason why we disciple our children. Or it includes those coming into the covenant community for the first time as believers in Christ. So that’s the first task.


Second, making disciples also includes teaching the commandments of God. That is captured in verse 20. After the call to baptize, Jesus adds, “teaching them to observe all that I have commanded you.” Being a disciple requires learning God’s commands and pursuing them.


I think that all makes sense because that is what a disciple is and what he does. He believes and follows Jesus.


And the message to make disciples is simple. Faith, repentance, and obedience.


Matthew 28 does not speak to the message. But Jesus has been clear. The Bible is clear. The core message is repentance from sin and faith in Christ. That is what we call our children to, and it is the call for all humanity. Obedience is part of that call. It comes after faith and repentance, as a response to God’s grace. Again, Jesus said, “teaching them to observe all that I have commanded you.”


However, let me say this. The call to faith and repentance does not end when we come to Christ. No, actually, faith, repentance, and obedience is the ongoing call for a disciple. Ongoing repentance from sin; an ongoing renewal of our faith; and an ongoing commitment to observe the commandments of God.


Now, just to be sure, when you come to faith in Christ, you are secure in him. You are forgiven of your sin. That does not go away. Rather, renewing your faith in Christ, repentance from ongoing sin, and new obedience are in response to God’s saving grace. I just want to be clear about that.


Now, you may be thinking, “well, yeah, isn’t that obvious? Of course, a disciple should believe that Jesus died for his or her sin and should believe that we need to pursue holiness despite our ongoing sin.”


Well, the reason you may think those two points are obvious is because we teach them. We teach the heinousness of our sin before our holy God. We teach that the only path to God is by faith, repenting to God of our sin and trusting in Christ as our Savior. We teach that Jesus’ sacrifice on the cross is necessary to atone for our sin. And we teach that in our redeemed state, we are still sinners. We are redeemed sinners who struggle with sin but are empowered by God’s Spirit to pursue holiness – and God calls us to pursue him. That is the Gospel.


But let me say, that message is not emphasized in many parts of Christianity. Often sin is minimized. The word “sin” is not seen as culturally sensitive today. And so, some circles replace it with words like “brokenness” or “struggle” or “woundedness.” I am not saying that we are not broken nor struggle nor have wounds. But when those ideas are used in place of sin and not in connection to it, then the underlying problem of our separation from God because of sin is suppressed.


What I am saying is that the task of making disciples of Jesus begins and ends with faith, repentance and the call to observe Jesus’ commands.


2. How do we mature as disciples?


Ok, let’s move on to a second helpful question. Let me ask you, how do you mature as a disciple of Jesus?


It’s important to ask that question because the Bible calls us to mature in our faith. We call that maturity sanctification. It is the ongoing work of God’s Spirit where more and more we die to our sin and live to righteousness. The task of making disciples needs to include that lifelong pursuit. All throughout the Bible we are called to grow in our faith. We’re called to be conformed to the image of Christ. We are called to be filled with the knowledge of his will. Hebrews 5 calls us to mature from milk to solid food like children. Ephesians 4 calls us to mature into manhood, growing up in every way into him who is the head, into Christ. In 2 Timothy 3, we’re to know the Word that the man of God may be equipped for every good work. Romans 12, we’re to renew our minds.


We would be here all day if we were to go through every single passage that speaks of being conformed more and more to Christ. Rather than doing that, I picked one example that I find to be very helpful as a representative passage. 2 Peter 3:14-18 – it was our second sermon text. If you’ll turn there.


This is one of my favorite passages about our sanctification.


We’re going to focus on verse 18, but I don’t want to overlook the context.


The apostle Peter had just written about Christ’s second coming when he will make all things new. While we are waiting, we’re called in verse 14 to “be diligent” that we may be “found by him without spot or blemish…” And then a couple of verses later in verse 17, there is a warning against sin. It says, “…take care that you are not carried away with the error of lawless people...”


Then we get to verse 18 which is my favorite. If you only remember one thing about this sermon on discipleship, I want you to remember this verse. 2 Peter 3:18. It says, “But grow in the grace and knowledge of our Lord and Savior Jesus Christ.” I love it. Let me read it again. “But grow in the grace and knowledge of our Lord and Savior Jesus Christ.”


Look first at the titles given to Jesus. Lord and Savior. He is to be both. He is to be Lord over us as we live. We look to him, as Lord. He is to lead us in what is true and right and good. But Jesus is not only our Lord. Jesus is not just a model for living. His teaching includes more than just commands about how to live. He is also our Savior. He has redeemed us. He calls us, as I mentioned earlier, to faith and repentance.


And the command in verse 18 is to grow in two things: grace and knowledge of him.


·   First, we are to grow in grace. That is, more and more we need to see our sin and the depths of his mercy and love. We are to grow in our understanding of the cross and the hope of the resurrection in our suffering, and grief, and pain. That is all growing in grace.


·   And second, we are to grow in our knowledge of him. We need to know his Word, not for the sake of head knowledge but for the sake of knowing him, knowing God, in his fullness, and living out his commands.


You see, when it comes to discipleship, verse 18 is so very helpful. It directs us to the core things that discipleship needs to be about. It direct us to grow in the grace and knowledge of our Lord and Savior Jesus Christ. And that is very consistent with the rest of Scripture.


A few weeks ago do you remember that I sang you a song during my sermon? Remember it? “Read your Bible, pray every day, and you’ll grow, grow, grow.”


That was probably the first and last time that I’ll do that. Remember that we talked about the ordinary means through which God changes us. And what are those ordinary means? God’s Word, Prayer, and the sacraments. We considered Acts 2:42, about the early church, and we looked at Hebrews 4 as well as 1 Corinthians 10.


Our sanctification, that is, our growth in grace, comes through the Holy Spirit’s work in us as we engage in these appointed means – (1) reading and studying God’s word, (2) praying to the one true God of heaven and earth, and (3) participating in the visible signs through which he shows us the Gospel and strengthens our faith, Baptism and the Lord’s Supper.


And to tie that back to what I mentioned earlier, through those means, we are called again and again to repentance, to a renewal of our faith, and to further observance of and obedience to God’s word and will.


Here’s what I am saying. Any discipleship approach needs to include some aspect of those foundations. I’m not saying every discipleship approach needs to include all of it. But every discipleship approach needs to direct us toward maturing in Christ by… revealing our sin and his grace and commands… or directing us to God Word, prayer, and the sacraments. It is through those avenues, that God conforms us more and more to his image.


·   So, if a discipleship approach is only about loving as Jesus loved but mentions nothing about sin nor Jesus’ call to repentance and faith, then it falls short.


·   If a discipleship approach is all about being a better husband or wife, or a better doctor or electrician, or a better neighbor, but there’s nothing about the grace of God in Christ and being conformed to him and his commands, then it falls short.


·   If a discipleship approach is about the disciplines of the Christian life, but does not focus on knowing God’s Word and being in prayer, then it falls short.


I could go on with more examples. My point is that the Scriptures do give us a framework for making disciples. And that framework needs to be at the heart of our discipleship approach.


Discipleship at Tucker Presbyterian


Which brings us to our church – Tucker Presbyterian. Given what I’ve said already, how are we seeking to make disciples?


By the way, it’s entirely impossible for me to answer that question over the next 10 minutes.


But I do want to let you know that on the welcome table is a draft of our new philosophy of discipleship. We, as your elders, have been working on this for the last 2-3 months. It includes the foundations to discipleship, which I’ve just mentioned, but also includes our priorities in discipleship and how we desire to work those out… in worship, in our children and youth ministry, and our adult ministries, which includes our men’s and women’s ministries.


I can’t cover it all, but I do want to highlight 8 priorities or principles of our discipleship.


1. We believe discipleship begins in worship. This is really important. Corporate worship is where the means of grace converge, as I mentioned last week. God works through our worship, including our family or private worship. Through worship, he conform us to him as we declare salvation in Jesus Christ and praise God for his grace and mercy.


2. In our discipleship, we desire to foster a heart for missions – a heart for our neighbor and a heart for the nations. In other words, disciple making involves disciple making, which is calling people to faith in Christ. More on this one next week.


3. Discipleship needs to direct people to the local church. Local congregations, where God’s covenant people gather, are God’s ordained avenues for worship, discipleship, and missions. The sign of baptism is the sign of our ingrafting into Christ and therefore ingrafting into one another as a body of believers.


4. We seek to disciple one another across generations. God’s call for the church is to be a people of God together. We want our members, old and young alike, to know and care for and support one other in the task of discipleship. To be sure, we do not believe this should be the exclusive pattern. As Proverbs teaches, a brother is born for adversity, and as iron sharpens iron, so one man sharpens another. There is value in peer discipleship, but often times, churches overprioritize that and not intergenerational discipleship.


5. Every single one of us is called in one way or another to the task of making disciples. You may be a parent, you may be an ordained leader in the church, you may have been given one of several Holy Spirit given gifts mentioned in the Bible such as teaching or knowledge or wisdom. Even if none of that applies to you, you are still called to be a witness to your neighbor or co-worker or family member. We are all to be disciple makers.


6. This next one is about children and parents. Parents are ordinarily to be the primary disciplers of their children. However, not all children have believing parents or parent, nor are all parents available for different reasons. The church needs to support parents and children in the discipleship endeavor.o


7. Church discipline is a matter of discipleship. Two months ago, when we were in 2 Corinthians chapter 13, we considered the responsibility that the church has to disciple those whose sin is destroying the family of God or whose sin is unrepentant and grievous. We can’t unpack all of that here, but that sermon is out on our website and podcast. And let me remind you that the goal of church disciple is always repentance, renewed faith, and restoration.


 


8. Finally, number 8. Discipleship needs to happen in the context of fellowship. In Acts 2:42 intentional fellowship, or koinonia fellowship, is included with the means of grace. Fellowship is important. We believe discipleship happens in relationships with one another because we are brothers and sisters united together in Christ.


So, those are our priorities in discipleship: the priority of worship, a heart for missions, the centrality of the local church, discipleship across generations and in support of peers, assisting parents, church discipline, and all in the context of deep fellowship.


Conclusion


In summary, we do not believe there’s a one-size-fits-all pattern for implementing discipleship. However, that does not mean that all discipleship approaches are good. We need to evaluate each according to God’s pattern for making disciples which he has given in his Word.


And at its core, that pattern for making disciples involves (1) calling each other to faith and repentance and obedience in Christ, and (2) directing one another to the Word, prayer, and the sacraments. It is through those means that God will grow us in the grace and knowledge of our Lord and Savior Jesus Christ.
