Preached on November 30, 2025, First Sunday of Advent, at First Presbyterian Church of Rolla. Based on Isaiah 2:1-5.
Today, we start a new liturgical year with the first Sunday of Advent. My plan this year is to delve into the Hebrew Bible readings. Weโll see how it goes. Lots of preachers pull out the Old Testament to emphasize Godโs vengeance against evildoers, but you know meโthatโs not what I ever talk about. In Better Ways to Read the Bible, Zach Lambert listed four good lenses to use when we are reading any part of the Bible. The Context lens considers the broader context of any given passage. The Fruitfulness lens reads the text through the fruits of the Spirit and how it fosters them. The Flourishing lens is my main perspective: the kingdom of God is universal human flourishing, so how does the passage inform how we pursue that flourishing? And finally, the Jesus lens: all Scripture points to Jesus, who is the fullest expression of who God is and how God works in the world. So even though Iโll be talking about words written centuries before his birth, I do believe that our understanding of Jesus informs our understanding of the text, and vice versa.
But letโs start with the context. Isaiah is one of the major prophets, along with Ezekiel and Jeremiah. Some would include Daniel. Isaiah prophesied in Judah, the southern kingdom, in the latter half of the eighth century BCE, around the same time as Micah was active in Judah and when Amos and Hosea were active in the northern kingdom of Israel. The Assyrians were the main regional power at the time and were on the warpath. They besieged and ultimately conquered the northern kingdom. Then they marched south to Judah and besieged Jerusalem, but fell short, so Judah survived. Isaiah was active throughout the war.
All four prophets who were active during the Assyrian wars preached against the injustice throughout the two kingdoms. Isaiah laid the blame primarily on the leaders. Social injustice cannot be rectified with acts of worship. As Amos preached, โBut let justice roll down like water,ย and righteousness like an ever-flowing stream.โ
Isaiah and Micah both famously spoke of the day when the people would beat their swords into plowshares and their spears into pruning hooks. This was a bold statement in the midst of war. When a brutal army is at your doorstep threatening annihilation, nobody wants to hear that they should lay down their arms, but everyone wants to believe that a day of peace would someday come. Remember I said that the kingdom of God is universal flourishing, right? Well, flourishing requires peace. So why is there war?
In the ancient world, agriculture was the foundation of a nationโs economy. If you possessed productive farmland, you could grow crops that would feed your people. If you controlled productive pastureland, you could raise sheep, goats, and cattle to feed your people. So ideally, a clan, tribe, or nation would maintain control over good land, work it to get the most productivity out of it, and flourish.
But the other way to obtain the produce of the land was to just take it. Take it by force. For millennia, the purpose of war was to obtain resources. When the Assyrians conquered Israel, they exiled the people so that they could control the land and extract its wealth. Later, the Babylonians did the same to Judah. Thatโs the reason the Greeks and the Romans conquered Judea as well. The same motivation drove European powers to conquer and colonize the Americas and parts of Africa, Oceania, and Asia. Eventually, competing ideologies became a reason for war, but usually with an economic basis as well.
Letโs think about the major conflicts in the world today. Russia invaded Ukraine in 2014 to possess Crimea, which is an important gateway for them to access the Black Sea. More recently, they expanded their horizons and are seeking to control the major industrial portions of Ukraine. Sure, there is an ethnic argument they make, that these portions of Ukraine have many ethnic Russians in them, but the real reason is economic. Israel and Palestine have been locked in a struggle for almost 80 years. There are many reasons, but a big one is the economic deprivation of the Palestinians and their lack of freedom to flourish. A world in which swords have been beaten into plowshares is a world in which people focus more on producing wealth through their own efforts than stealing it by force or denying it to their enemies.
But I wonโt deny that there are times when war is necessary and appropriate. Someday, when Godโs kingdom comes in all its fullness, war will be no more. In the meantime, we need to muddle through and deal with the violence so prevalent in the world. What is the appropriate response of a Christian? Well, in the early days, all Christians were pacifists. St. Martin of Tours was a famous example. He was a Roman soldier who converted to Christianity and became the first recorded conscientious objector. After he left the Roman army, he became a monk, then a priest, then a bishop. His feast day is November 11, which became a traditional day on which to sign peace accordsโmost famously at the end of World War I.
But avoiding war sometimes amounts to allowing a bully to prey upon a weaker nation. So Christians developed just war theory. There are three parts of it: jus ad bellum, which are principles for going to war, jus in bellum, which are principles for conducting war, and jus post bellum, which are principles for the aftermath of war. Donโt worry, this isnโt a lecture on just war theory. Iโll just highlight a few things.
The most important condition for going to war is possessing just cause. Wars of aggression are never just. Self-defense is almost always just. Things get tricky when weโre talking about a third party. Consider the first Gulf War. Iraq invaded and conquered Kuwait. Clearly, Kuwait had the right to defend itself against the invasion, but they did not have the ability to do so. The US led a coalition to repel Iraq and re-establish Kuwaitโs sovereignty. We had the ability, but did we have the right? I would say yes, but some would argue against me. So then fast forward to Ukraine. What really is the difference between Iraqโs invasion of Kuwait and Russiaโs invasion of Crimea? Not much, except that the US didnโt think it was a good idea to challenge Russia on the field of battle.
The main principles of just conduct of war are discrimination and proportionality. Discrimination means that you only attack enemy combatants, not civilians. Proportionality means that the force you use should not exceed the just goals.
The key to long-term peace, though, lies in jus post bellum, the just way to end and resolve a war. Again, there is discrimination and proportionality: the losing government should be punished, but not necessarily the non-combatant people of the losing nation, and the claims of victory should be proportional to the nature of the war. If the end of the war is not just, then the seeds of future conflict are sown.
In 1871, the Franco-Prussian War ended with Prussia controlling Alsace-Lorraine, a region of France that they had conquered. The Prussian Empire became the German Empire, one of the participants of World War I. In 1919, Alsace-Lorraine was returned to France, then in 1940 it was re-taken by Germany. Finally, in 1945, it was returned to France. Which nation should control it? I donโt know, but the fact is that both nations felt that they had a historical right to control its people, its land, and its resources. Leaving the issue poorly resolved presented a reason, or at least an excuse, for future conflict.
In many cases, wars end with a truce rather than a real peace. Consider whatโs going on in Israel and Gaza right now. On October 7, 2023, Hamas invaded Israel, starting a hot war in Gaza. On October 10, 2025, just over two years later, both sides ratified a ceasefire deal that had many conditions. Yet 345 Palestinians have died in the conflict since the ceasefire was settled, including in an episode last Wednesday. I donโt think either side is really committed to the ceasefire because it does not really resolve the underlying problems. It is a temporary solution to a long-term problem that has existed for generations and has been prolonged by people who profit from a continuation of hostilities.
We live in a violent world. What are our obligations, as Americans? Well, we have helped to create many of the conditions that have led to war. For example, thirty years ago, the US partnered with other nations to convince Ukraine to divest of its nuclear weapons, in exchange for security guarantees. This was clearly the right thing to do at the time, and yet it left Ukraine defenseless in the face of Russian aggression. We have an ongoing obligation to Ukraine because of our involvement back then. As the leading superpower for decades, our actions have sown the seeds of future conflicts around the world. We cannot simply turn our backs on our allies or on defenseless nations that were destabilized by our actions.
This is not to say that the US did anything wrong, necessarily. The problem is that resources are finite, land is finite, and conflicts are inevitable. Even when we do our best to negotiate just resolutions to any conflicts, someone will end up feeling short-changed. I mean, who has the right to control Israel, Gaza, and the West Bank? Both Israelis and Palestinians have legitimate claims. Who has the right to Alsace-Lorraine? That seems to be settled now, but there was a time when both France and Germany had legitimate claims.
The kingdom of God is universal human flourishing. Yet in this finite world, it is often impossible to achieve flourishing for everyone. And so, we always feel like we donโt have enough. Or maybe you feel like you personally have enough, but others in your family or your community donโt. Or maybe a whole nation feels like they donโt have enough. And so, we want more. Always more.
Since Iโm preaching on the Old Testament, let me reach back to the Mosaic covenant that established Israel as a nation, as Godโs people. The Ten Commandments spelled out all the ways that people should act so that they would love God and love their neighbor. There are nine commandments that talk about things a person should or should not do, and then the Tenth Commandment is different. It speaks of the heart: โYou shall not covet your neighborโs house; you shall not covet your neighborโs wife, male or female slave, ox, donkey, or anything that belongs to your neighbor.โ Coveting is an emotional response to seeing that your neighbor has something that you think would make your life better. Coveting is the root of the evil addressed in the rest of the commandments. When you let covetousness take root in your heart, you wonโt let anything stand in the way of obtaining the object of your desire. Maybe you will steal it, maybe you will even kill for it.
But Isaiah spoke of a state of being where Godโs justice leads to universal flourishing, so that no violence will be necessary. In Godโs realm, everyone has what they need. In Godโs realm, interpersonal violence is unnecessary. In Godโs realm, war is unnecessary. There is no need to fight someone to take their land or resources, nor to defend yourself against aggression, because everyone will have the land or resources they need.
But what should we do in the meantime? In this finite world filled with violence, how can we live into Godโs kingdom? Well, the first step is to see, truly see, one anotherโs needs. Rather than flattening people or nations into stereotypes, see them as fellow children of God who need food, shelter, safety, belonging, and self-actualization. See them through the eyes of their own culture and life experiences, without projecting your own beliefs and social conditions onto them. Then, having seen their true humanity, seek true shalom: peace, wholeness, and well-being. Cornelius Plantinga wrote:
The webbing together of God, humans, and all creation in justice, fulfillment, and delight is what the Hebrew prophets call shalom. We call it peace, but it means far more than mere peace of mind or a cease-fire between enemies. In the Bible, shalom means universal flourishing, wholeness and delight โ a rich state of affairs in which natural needs are satisfied and natural gifts fruitfully employed, a state of affairs that inspires joyful wonder as its Creator and Savior opens doors and welcomes the creatures in whom he delights. Shalom, in other words, is the way things ought to be.
Cornelius Plantinga, Jr., President Emeritus, Calvin University
The way things ought to be. Godโs realm is the way things ought to beโnot the violence and bloodshed and poverty and suffering we see all around us. Our world is so far from shalom itโs sometimes hard to imagine. We may never be able to achieve it. But with Godโs help, through our beloved Savior who was born two thousand years ago, we can pursue it, one person, one decision, one relationship at a time. And in doing so, we will truly worship the Prince of Peace, not just with our words and our gatherings, but also with our reconciling actions in our families, community, nation, and world. Amen.
