Knowing the Unknown God

Readings for the 6th Sunday of Easter, Yr. A – Acts 17:22-31; Psalm 66:8-20; 1 Peter 3:13-22; John 14:15-21. This sermon was preached at Grace & Glory Lutheran Church in Palmyra, VA on May 10, 2026.

In the Book of Acts, we encounter the early Church on the move. Starting in Jerusalem on Pentecost, we hear of its spread from person to person through large cities toward what was considered at the time to be the center of the world in every sense –  Rome. This movement depicts the fulfillment of Jesus’ command (if not prophesy) heard in Acts 1:8 that receiving power when the Holy Spirit has come upon them, his disciples will be Jesus’ witnesses to the ends of the earth. This is that exact same power that we receive through our faith and baptism. Our little church community is directly connected to this grand, miraculous, universal story…Our faith has come person through person, generation through generation, until the source of that story called us to gather here today including those on Zoom.

Also, please note that this movement was not haphazard even as it spread in unpredictable, sometimes uncontrollable, willy-nilly ways. Yes, the Apostles likely discussed and planned their evangelism. (There’s evidence of this in scripture.) Yet ultimately, it was Spirit-activated and led. Relationship by relationship, crisis through crisis, the Holy Spirit used people and circumstances…even what seemed the worst of circumstances…to introduce Jesus to the world…to make Jesus known.  

So just imagine St. Paul moving from town to town along the Via Egnatia, a primary Roman road connecting the eastern and western parts of the Empire. He traveled primarily (most likely) on foot, but occasionally by ship. On his way, Paul picked up work as a tent maker and leather worker to help pay his way, but it also introduced him to strangers who were soon to become his siblings in Christ. Paul traveled over 10,000 miles…hard to believe, but true…often with great risk and personal cost. Yet, he didn’t just pass through. He left a mark as his life touched the lives of others – the mark and seal of his own baptism, Christ’s cross was shared.

Certainly, the growth of the church was facilitated by the modern roads and ships of that time, just as the digital age helps us get the word out, but it was ultimately ordinary people who brought the Good News to others that proves critical. Someone must speak of Jesus for the Good News to spread. Someone must model his love and make it concrete in a world so in need of love. The prophet Isaiah rightly proclaimed, “How beautiful on the mountains are the feet of those who bring good news, who proclaim peace, who bring good tidings, who proclaim salvation, who say to Zion, ‘Your God reigns’” (Isaiah 52:7).

In knowing the “unknown god,” we inherit some responsibilities. According to the theologian, Carl Braatan, and others, our very own Martin Luther saw the Church as “an acoustical affair” (ein akustisches Geschäft). Echoing Romans 10:17, Luther emphasized that faith primarily comes through hearing the preached Word of God, rather than through visual spectacles, works that we do, or any internal contemplation. “Stick your eyes in your ears,” Luther is reported to have said. Rely on the spoken word, particularly as we hear in scripture. More than visual evidence or human reason, that reveals Jesus. In contrast to the non-Reformation congregations of his time, he argued that the churches of the Reformation were “mouth-house churches” (Mundhausen) where God’s work was spoken. The Word of God is heard through the liturgy and the readings. (If you look closely, you can find scripture in our liturgy.) The Word, which is Jesus, is couched somewhere within every sermon (even bad ones, he argued). And he highly valued music and hymns famously saying, “Next to the Word of God, the noble art of music is the greatest treasure in the world.”

Yet, we all know that not everyone will come to our building. And we ourselves cannot stay here. The Church must go out into the world. “So go into the highways and byways, and invite everyone you find to the wedding feast,” Jesus taught through a famous parable (Matthew 22:9-11). As this congregation’s first pastor taught as recently shared in a congregational history, the Church is not ultimately the building…it is us with all the saints. And the Church should not allow any walls to close us in. In our daily lives, our sacred callings (our vocations lived out in roles at school, work, or retired life, in and out of family or within tribal boundaries), we are the Church in the world. Trying to break out. Trying to share the love of Christ with everybody. For, where we are God is with us too, and more than that, we are declared to be Christ’s body.  

Shortly after the Reformation had begun in 1522, Luther preached:

“When a prince sees his neighbor oppressed, he should think: That concerns me! I must protect and shield my neighbor….The same is true for shoemaker, tailor, scribe, or reader. If he is a Christian tailor, he will say: I make these clothes because God has bidden me do so, so that I can earn a living, so that I can help and serve my neighbor. When a Christian does not serve the other, God is not present; that is not Christian living.[i]

What he is saying it that how we live our lives and relate to others is a kind of sermon too. It testifies to the God we know in Jesus.

In the time of Acts, the Church grew by fits and starts despite persecution and setbacks. St. Luke who wrote the Book of Acts shares this experience in such a way that the story juxtaposes those who resist the Gospel with those who accept it. We need to remember that Acts was originally to encourage and urge on early believers facing rejection from their families, economic consequences for their faith, and in some cases, outright persecution and death. Even the great Apostles are shown at times in Acts to doubt, argue, or make mistakes. So despite struggles or want, Luke wants us to remember that this process is the will of God and Spirit-led, and all things will work for the good of those that love God (Romans 8:28).

Today we hear that while waiting for Silas and Timothy to rejoin him, Paul addresses Epicurean and Stoic philosophers on Areopagus Hill (also known as Mars Hill). Our true God, Paul indicates, was already reaching out to them before these wise philosophers and teachers ever knew God by any name. This was evident by the altar he saw dedicated to “the unknown God.” Inherently, they somehow knew that there was more to be found, understood…known. Paul points out that God might use the ordinary and even profane to connect us…to invite us into a relationship…with the One we have been waiting for…Jesus. Nothing can stop God’s will, and as Christ’s disciples share the Good News of Jesus in the marketplace, synagogues, and homes, others become enfolded into God’s purpose. They come to know Jesus and believe.

Now please understand, there is no “one size fits all” formula for evangelizing. Like Paul, we, too, have to consider our context, abilities, audience and obstacles. First, I would suggest that we all come to understand and trust that God is all around us and always with us. We can indeed encounter the Risen Christ through all good things. This is how Julian of Norwich came to understand that even in the simple beauty of a lone hazelnut one heard preached that God made it, God loves it, and that God keeps it. This is why Luther would speculate (inspired by Romans 8) as he deeply grieved the death of his beloved dog that he fully expected to meet him again at the Resurrection, and he would have a golden tail. It is why John Calvin later taught in his systematic theology that even a sunrise can be used by God to draw a person outside of themself and ultimately toward Jesus Christ. Like the people in Athens, the person might not understand who this unknown god is (not yet!), but they hear something calling them, and they know it hints of the sacred…the ultimate love, beauty and truth we know to be God – Father, Son, and Holy Spirit.

Second, we, too, as human beings are created “things,” a being in our shell of a body. And yes, as people often say, God is in our hearts. Our selection from John 14 this morning spoke of this new reality with the Risen Christ. Christ is in us and we in him. Jesus might be seen in us as we serve, but he is also crying out from the bodies of those oppressed, hungry, or suffering in anyway…crying out for us to help him.[ii] My past spiritual mentor, Br. Roger of Taizé, argued (echoing ancient teachings of the Church) that Christ’s light shines within us, transforming inner darkness, but it is also calling us to recognize the same “silent wait of a presence” at work in all people. There’s a divine spark or light already burning within the hearts of other before they know it; waiting to become known and grow in its brightness.  

How can we serve God at all times and every place? I understand that we are not the great Apostles. Yet, we can seek to model Christ and his teachings in all our dealings as they did – loving God and neighbor along the way. We need not be afraid to speak of Christ…acknowledging him as Lord of your life…as why we try to do what we do…even amidst our imperfection, hesitancy or doubt. Don’t deny or hide that we follow Jesus. Just speak of Jesus, as we know him in our life. This does not require a seminary degree. It does not mean you must understand every theological argument or scriptural attestation about Jesus, but if you are a Christian…why? Who encouraged you? Who shared this faith with you? What calls you? Why do you do what you do? Start there, testify to what you do know, and the rest will come later within God’s timing and plan.

In sharing our faith, we don’t need to be pushy or performative. We don’t need to know it all. Instead, let the authentic, gentle nature of our own love and own seeking (our questions) be what attracts others to faith in Christ. Martin Luther and many other spiritual masters argued that faith should not (could not) be forced. Jesus invited people to follow him, but he always left it up to them to do so or not. No one can identify Jesus as Lord without the Spirit’s help. As we relate to others, offer them the patience, the forgiveness and love that we ourselves have received first. We can trust the Spirit will do something, although we might never know exactly what in our lifetime. And if we don’t have the answers, point them to someone who might and offer to lovingly wait with them for their answers.

Third, as found in Hebrews 10:25, don’t neglect the assembly. In worship, fellowship, stewardship and service, you are part of the body of Jesus Christ, and it cannot be whole without you…It cannot be as vital as it is intended to be if you are missing. Yet know this, too…Through your intentional, sincere participation…whether on Zoom, in the worship space, serving, or praying for others or the Church and its concerns…as you are able to; not with guilt or obligation but out of joy…your own faith will grow as well. Absolutely, Jesus will be made more known to you. You will meet the Risen Christ as you continue to knock, seek, and serve. Your presence might also encourage someone else’s participation in our shared life faith in ways you will never know.  

Our Orthodox brothers and sisters tell a story where one man asked a priest: “If God is everywhere, what do I go to church for?” To which the priest replied, “The whole atmosphere is filled with water; but when you want to drink it is good to go to a fountain or a well.” Through fellowship, the sacraments, the preaching and teaching, our shared service, and even quiet times, grace enters more deeply into our lives. We need to gather at times in our homes including through our Shepherds’ Team, through the internet, in the sanctuary and elsewhere out in the world.

Yet never forget, even apart, we remain part of this communion called Church. We are connected to all those believers that have come before us, those that gather throughout the world in the present, and all those believers yet to come. We are never alone…always connected by the Holy Spirit. “Since we are God’s offspring, we ought not to think that the deity is like gold or silver or stone, an image formed by the art and imagination of mortals.” Oh, no…our true God is much more than that. God is very much alive in the creation around us, in the Christ who is risen, and on the move in and through us and the world around that surround us as the Holy Spirit blows us toward where God needs us to be. Jesus will never leave us orphaned (John 14:18), my friends, and he wills to be made known in and through our lives. Amen.
