We Need the Trinity (A Discussion of the Three-in-Oneness of God)

Pastor Mike
A man in a robe is walking through the desert.

I am so thankful that there are people in the world who know how an internal combustion engine works. I am grateful to God that the secret knowledge of how to repair such an engine has been passed down through the generations ever since this technology was invented. When my own vehicle is having issues, there is someone out there who is capable of helping me fix it. There is no doubt that aspects of my life would improve if I understood more about how a car works and how to fix it. Sad to say, I just don’t. And yet, I survive.


Because when my son needs to go to the hospital, knowing how the car works is not nearly as important as knowing how to drive it. When the ball rolls into the street, and the basketball player chases after it, understanding how hard one needs to press on the brakes to stop the car is more important than understanding how the brake mechanism works. When surprised with a crisis or emergency, knowing how to use the technology or information is much more important than knowing how to explain the information.


That’s why the goal for this discussion will not be to explain the doctrine of the Trinity in a as satisfying a way as your mechanic (or you!) can explain how an engine works. Everyone who has tried, throughout the history of Christianity, has failed.


Unlike an internal combustion engine, God is not an invention of mankind. His thoughts and ways are higher than ours (Isaiah 55:8-9); his knowledge, his being surpasses ours (Isaiah 40:13-14). Every time we confess God to be almighty, divine, the “LORD,” we recognize how superior he is to us (Isaia 40:28).


So, why bother? If God’s essence cannot be fully comprehended nor explained, why even try? Why “invent words,” as we are often accused of doing with the words “Trinity” or “Triune,” which don’t appear in Scripture (which is true, they don’t)? Why did the early church fight tooth and nail to against trinity-deniers, to protect a doctrine that is by nature incomprehensible?


First and foremost, because God reveals it to us. The words Trinity (noun) and Triune (adjective) do not occur in Scripture, that’s true. But the concept is all over Scripture’s pages. We get little glimpses of it in the Old Testament. In Genesis 1:1-3, God the Father, Son, and Holy Spirit are all present in the creation of the world (compare with John 1:1-4). God commanded the priests of Israel to pronounce a three-fod blessing over the congregation, and Isaiah has a vision of God’s glory where he hears the three-fold praises of the angels, “Holy! Holy! Holy!” understood by many to be hints at the trinity (Isaiah 6:3). (There is more we could say about the Trinity in the Old Testament, but we’ll stop there for now.)


The New Testament reveals the Trinity a bit more explicitly. At Christ’s baptism, God the Son was being baptized while God the Father spoke, and God the Holy Spirit appeared as a dove (Mark 1:9-12). The three-fold blessing that hinted at God’s three-in-oneness in Numbers becomes more explicitly trinitarian in Paul’s closing blessing when he says, “May the grace of the Lord Jesus Christ, and the love of God, and the fellowship of the Holy Spirit be with you all” (2 Corinthians 13:14). Peter summarizes the contributions of each person of the trinity in his gospel preaching (Acts 5:30-32).


The Bible never attempts to explain how it is possible that God can be only one God (Deuteronomy 6:4) and yet also exist as three, distinct persons (Father, Son, and Holy Spirit). However, God’s Word does reveal this truth to us, despite the difficulty in comprehending it. See 1 Corinthians 2:7-10, where Paul describes the truth of Scripture to be “a mystery” and “the things God has revealed to us by his Spirit.”


So, if God is so far above us that we can’t understand him, and if he picks what to reveal about his incomprehensible will and nature to us, and if he chose to reveal the fact that he is triune to us, doesn’t it make sense to conclude there must be a good reason?


Return to the example above. If I know how to explain an internal combustion engine, that’s great. It’s more important that I know how to use it, especially when in crisis.God reveals the truth of his triune nature to us, because this is a truth we need to know. This is information that we can and should use, because we’re in crisis!

To a humanity that is in crisis of identity, God reveals, “I have formed you, created you, and love you, you are mine” (see Isaiah 43:1). He says, “I will always protect, preserve, and provide for you,” (see Psalm 145:15-16). These are activities ascribed to the person of God the Father.


To a human race that is in crisis of belonging, of acceptance, knowing we need love but not knowing where to find it, God reveals, “I am a God of grace, of unconditional love. I don’t hate you, but love you everlastingly,” (see John 1:14,18). To a human race plagued by gnawing guilt and agonizing shame, God creates a relationship of safety, of forgiveness, of everlasting and eternal life (see 1 Timothy 2:5-6). This is what we ascribe to the person of God the Son (Jesus).


To a human race in a crisis of direction, of ignorance, in need of guidance and hope and comfort, God reveals, “I am with you. You are mine. I will yoke myself to you and always be with you. I will lead you,” (see Galatians 5:22-26, 1 Corinthians 6:11, Romans 8:4 and 8:9). This is what we ascribe to the person of God the Holy Spirit. 


Simply observe how Paul uses the work of God the Father to reach the hearts of the people of Athens in Acts 17:22-34. See how the forgiveness and love of Christ is used to spur us on to similar acts of service and love to one another in Ephesians 4:32-5:10. Go to Romans 8:14-17, 8:26-27, 15:14-16 and 1 Corinthians 2:9-16 to be comforted by the truth of the Holy Spirit’s work. The trinity is a doctrine to be studied, certainly, but it is a beautiful doctrine that begs to be used!


That’s why leaders in the early Christian church fought tooth and nail to protect it. The stakes were high! To abandon or misrepresent the doctrine of the trinity meant depriving anxious souls of the comfort they need, wayward wanderers of the direction they sought, and depressed and lonely hearts of the belonging and love that is so clearly there. That’s why it was worth their time to come up with three Creeds (the Apostles, the Nicene, and the Athanasian) that succinctly and directly express what Scripture teaches about each member of the Trinity. This is that important.


Next time you worship with us (and I so hope and pray that this is soon!) count for yourself how many references to the trinity there are in the service. More than that, observe how the doctrine of the trinity is used throughout! See for yourself how beautiful this doctrine is. Put it to good use. After all, that’s why it’s there!


This was a very quick discussion of a complex topic. If you have more questions and thoughts, we’d love to keep the discussion going! Join us any Sunday for Bible class at 9am, and service at 10:15am, and/or reach out to us directly via the Contact page. God bless you!

Jesus with a crown of thorns and sunburst. Text: Jesus' Threshold Mission, An Advent Series.
By Pastor Mike December 4, 2025
A boyfriend and girlfriend enter a church. After a ceremony, they leave husband and wife. What happened? Words happened. A soldier enters a change of command ceremony, but leaves with a whole new set of responsibilities and honors conferred upon her. What happened? Words happened. When a pastor pronounces a couple man and wife, or an officer pronounces a soldier as the new leader, a new reality is being constituted – and simply with words! Words clearly have tremendous power. But sometimes they fail, don’t they? You told your son to finish his game and come sit at the table. He did not. What happened? Were your words not enough? You poured out your feelings with words to your best friend, hoping he would give you sympathy, but instead reacted coldly. Was there something wrong with your words? Not necessarily. But sometimes words fail because of the hearer. And no one knew this better than the prophet Moses. As God’s chosen leader for the Israelites, time and again he saw them listen to God one minute only to abandon God in the next. At the base of Mt. Sinai (aka Mt. Horeb) Moses watched the Israelites fling themselves headlong into disgusting idolatry only moments after receiving instruction straight from God’s mouth. God did not overlook that incident. He punished the idolatrous Israelites swiftly and terrifyingly – so terrifyingly that they begged Moses to stay between them and God like a scrawny kid hiding behind a bigger kid. Moses stayed in his position as mediator between God and Israel, as a prophet whom God would give his words to bestow. So Moses led with words. Words were the tool that God gave Moses to guide Israel. That’s the job of a prophet, after all. Moses tells the Israelites to expect this situation to continue: 15 The Lord your God will raise up for you a prophet like me from among you, from your fellow Israelites. You must listen to him. 16 For this is what you asked of the Lord your God at Horeb on the day of the assembly when you said, “Let us not hear the voice of the Lord our God nor see this great fire anymore, or we will die.” 17 The Lord said to me: “What they say is good. 18 I will raise up for them a prophet like you from among their fellow Israelites, and I will put my words in his mouth. He will tell them everything I command him. 19 I myself will call to account anyone who does not listen to my words that the prophet speaks in my name. Like Moses, God would send more prophets. You may know some of their names: Elijah and Elisha, Isaiah, Jeremiah, Hosea, Amos, Daniel, Ezekiel. Each of them came with powerful words. Each of them came with the message God had given them to speak. Just like Moses, each of them experienced the bitter disappointment of their countrymen despising the message. They were laughed at, threatened, beaten, pursued within an inch of their lives – and many of them martyred for that powerful word. Time and time again, the hearers are the weak link. Is that the way it’s going to be this Christmas? Are we going to be the weak link in communication again? I say “again,” because even in my most earnest moments of wanting to hear God’s Word and take his message to my heart, that same heart struggles to understand and put it into practice. Each year, you and I both struggle to take home the true meaning of Christmas – that it is more than just a busier time of year and a weirder time at church. With how hard-headed the human race can be, it’s surprising that God keeps “trying” with us; keeps speaking to us. If the Christmases before are any indication, this Christmas is going to be just as much of a challenge to my hardheadedness to hear the meaning of it all. However, consider this: in a wedding, if the groom-to-be is daydreaming during the pronouncement of marriage, does he leave that church a single man? No. If a soldier sneezes during the words that confer her new command upon her, does she leave unemployed? No! The power of the words remain, because in that moment, their power doesn’t depend on the hearer. It’s when you’re commanding your kids to get off the Xbox that they can choose not to listen. When words are used to declare a new reality, though… that’s different. These verses aren’t just speaking about the long line of prophets to come. They are ultimately true, and true in the fullest sense, in Jesus Christ. As the Son of God in human flesh, Christ was set apart as a prophet. God the Father “raised him up” from the same stock as the rest of the human race. He is like us in every way, yet without sin. He is our empathetic Savior, in the trenches with us. But unlike Isaiah, Amos, Elisha, Jeremiah, or Ezekiel – men called out of other occupations in order to become prophets of God – this prophet is born into his prophetic ministry. Even the circumstances of his birth declare a powerful prophetic message: Your God comes to you not in rage or vengeance, but in gentle humility. This is a message worth listening to. And the way that we “listen” is both by hearing what Jesus has to say and watching what he does, since his actions bear witness to his message. His actions speak just as loudly as his words. And his message is not, “Do better,” or “Get your act together.” We already had that message! And we already terrified by its implications: “We can’t do better, we can’t get our act together, so what will happen to us?” But Jesus arrives in the manger on Christmas Eve as the Living Word, to communicate a new reality – one better than a pastor pronouncing over a couple that now they are married, or even that a soldier now has her dream job. Jesus arrives as a prophet, as a living and breathing prophetic message that, “God and sinners are reconciled.” He declares it with his words, speaking “Your sins are forgiven.” He proclaims it with his actions. Jesus did not come only to command. Jesus came to declare: good news to the poor; freedom for the captives; release from darkness for the prisoners; to proclaim the year of the Lord’s favor; to comfort all who mourn (Isaiah 61:1-2). He came to speak the new reality of grace and peace into being. And while Jesus’ living messages of our need for salvation, and the certainty of God’s grace are not fully different from the prophets of the Old Testament, he does speak in a unique way. Instead of a man given the words by God to speak to us, he speaks as God himself. He says things like, “Truly I say to you…” He speaks not just about human kingdoms but a heavenly kingdom, revealing to us through many parables what the kingdom of heaven is – speaking as someone who personally knows! Jesus comes to show us why we really matter to God, why we know he is truly with us, and how we know we’re saved. In the end, we are saved by his ultimate declaration from the cross, “It is finished.” Those powerful words sealed your fate for all eternity. You are his, he has declared it. He was born so that he could speak these words. With the power of God himself, speaking through a human mouth, he has declared to you the everlasting peace of God’s unconditional grace.  That means that any other human mouth that declares the same thing does the same thing. You have in your possession this powerful word. You have in your heart, mind, and soul the powerful declaration to forgive sins. Jesus even says that when you proclaim the same message of grace and peace, he is declaring it through you. When you forgive sins, he forgives them. When you proclaim comforting release from the darkness of guilt and shame, he proclaims it through you. Who wouldn’t want to listen to a sweet message such as this? And why wouldn’t we celebrate the moment the eternal God was born into our human race in order to speak to us this blissful comfort of the gospel? So maybe remembering the reason for the season won’t be that hard at all. In fact, Jesus’ word has a way of powerfully piercing through our stubbornness and getting into our hearts. Rest assured he can and will do so again through the gospel this Christmas. Pastor Mike Cherney

20 Looking at his disciples, he said: “Blessed are you who are poor, for yours is the kingdom of God. 21 Blessed are you who hunger now, for you will be satisfied. Blessed are you who weep now, for you will laugh. 22 Blessed are you when people hate you, when they exclude you and insult you and reject your name as evil, because of the Son of Man. 23 “Rejoice in that day and leap for joy, because great is your reward in heaven. For that is how their ancestors treated the prophets. 24 “But woe to you who are rich, for you have already received your comfort. 25 Woe to you who are well fed now, for you will go hungry. Woe to you who laugh now, for you will mourn and weep. 26 Woe to you when everyone speaks well of you, for that is how their ancestors treated the false prophets.

There! Now that we’ve cleared up all the misunderstandings above giving an offering, we are all ready to worship God in this way with regularity and joy! I’m just kidding. We’ve only touched on a few of the false conceptions that are possible. Because giving is an act of sanctification – a fruit of faith, thankfully offered to God in response to the gospel – it is something to “grow into.” There may still be misgivings, questions, and reluctance. Some readers may have been seriously hurt by church leaders who prevailed too strongly upon their debit cards and bank accounts. To those, one blog post will not be sufficient to restore the act of giving to its Scriptural, rightful place. For others, giving was never properly explained as a fruit of faith, not an act that earns goodness from God. To those, I pray this discussion has been helpful. I write this post as one who is himself growing in the act of giving. May God continue to shape our understanding of how to use our gifts to his glory. Giving to God is not a science. The act of giving looks differently among Christians, just as their acts of service and fruits of faith look differently. There are no hard-and-fast equations. We can’t say that giving an offering ensures that you’ll get rich in return (maybe God will choose to bless you in this way, maybe not). We can’t say that giving will come easy once you have a more stable income (your sinful nature will likely resist no matter how much income you have). We can’t say that you should never feel concerned or self-critical over your giving (is there ever an amount that will properly express your thankfulness to God?). So, I would say that giving is much more of an art. After taking in all of Scripture’s guidance about how to approach the act of giving, we proceed using our best judgment. We start with the gospel, meditating on what wonderful things God has done for us through Jesus Christ. We then look at the gifts God has given to us: our finances, our time, our personality gifts. We envision how to respond to God’s goodness with these gifts. While there are some acts of giving that will look very similar among various Christians (for example, we all give of our time when we attend worship and Bible study together), each one of us goes through our own process of deciding how best to respond to the gospel with our gifts. We submit our hearts to God for audit, recognizing that there are often mixed motives within them (Psalm 139:23-24). We rely on God to work within us and through us even as we thank him (Philippians 2:13). After all, this is about our relationship with God – not about securing it for ourselves with offerings, because it is already secure in Christ. Rather, it is about living out a relationship of worship with God, expressing to him and to the world what he means to us. To that end, let’s close with these verses from Hebrews: “Through Jesus, therefore, let us continually offer to God a sacrifice of praise—the fruit of lips that openly profess his name. And do not forget to do good and to share with others, for with such sacrifices God is pleased.” (Hebrews 13:15-16) God bless you as you find joy in God’s pleasure over you for Christ’s sake, and as you respond to this gospel with thanksgiving!

This is a very common conception of the offering, and up to this point it might appear that we also teach the tithe – the practice of giving one tenth of one’s goods as a matter of the law, and not to deviate from that percentage. This is commanded to the Old Testament Israelites in passages such as Leviticus 27:30. But Christ has set us free from the letter of the law (Colossians 2:14, Colossians 2:16-17, Galatians 4:4-5). When the New Testament commands the act of giving, percentages are not mentioned. What is mentioned, however, is that giving be proportionate (1 Corinthians 16:2), generous (2 Corinthians 9:6), done with joy (2 Corinthians 9:7), and a good work sprung from trust in the Lord (2 Corinthians 9:8-11). This is not as specific as the tithe rule. It requires one to spend time reasoning out what a manageable and reasonable gift looks like for them, while still reflecting the thanksgiving and generosity that they wish to communicate in response to the gospel. In many households, ten percent remains a useful benchmark for giving, but must not be treated as a law. Some households will not be able to afford that amount. For others, “proportionate” giving means giving much more than ten percent. It is a lot easier for church leaders to make hard-and-fast rules to “keep people in line,” rather than offer these general encouragements. However, if we remember that giving is an act of worship in response to the gospel, we will avoid strictly laying down ground rules that Scripture no longer enforces. Instead, we will focus on sharing the beautiful gospel with our members, friends, and community, and allow the Holy Spirit to create and nurture the gospel joy that inspires acts of thanksgiving. Likewise, if someone’s giving is “off-kilter,” we don’t want to address their giving with the desire that they “get those numbers up.” That would convey that our worth in God’s family comes from our works. Instead, we express concern over their connection to the gospel, and nurture their relationship with Jesus through Word and Sacrament. Then, and only then, can we discuss what a proper response to the gospel looks like in our giving. Go to next post in this series
