The Squatter and the Garden: from Eden to Babylon and Back Again
The prophets understand this with agonizing clarity. Isaiah's great comfort chapters (40–55) frame the coming redemption from Babylon as a second Exodus, surpassing even the first. The geography carries the weight: to be delivered from Babylon is not just to go home. It is to be restored to the whole trajectory that Babylon represents the negation of.
This is also, of course, why Daniel is the book it is. Daniel and his friends are not merely civil servants in a foreign administration. They are the covenant people stranded in the epicenter of everything God has been working against since Genesis 11 — and they must bear witness there, in the city of man, to the God who rules all cities and all kings.
Recommended Resources on Revelation
Here are some recommended resources for further study, prepared for those who’ve just studied a brief series on eschatology with me. This is also a good place to pick up helpful material in preparation for our upcoming sermon series on Revelation, starting in mid-August.
A Guide to Reading Revelation
Before we consider what Revelation is, we need to reckon honestly with why it so often defeats us. Most Christians who pick up this book find themselves lost within a few chapters — bewildered by the imagery, uncertain about the timeline, and vulnerable to whichever confident interpreter they encounter first. Three deficits account for most of the confusion.
Faithful Under Fire - Message Four: The King’s Exile
God has tender mercies for our pain. He has hard mercies for our pride.
But If Not - Message Three in Faithful Under Fire, Studies in Daniel
“But if not…” says that if God, for reasons of his own that we cannot see and may never understand, chooses not to intervene in the way we hope, we still won’t bow. The obedience is not contingent on the outcome. The loyalty is not conditional on the rescue. We serve him because he is God, not because he has agreed in advance to protect us from all consequences.
Faithful Under Fire, Sermon Two: The Rock of Ages
This little stone — humble, subversive, seemingly insignificant — strikes the statue at its feet. Not at the head. Not where it looks strong. At the feet. And the whole thing collapses. Gold, silver, bronze, iron, clay — "they became like the chaff of the summer threshing floors; and the wind carried them away, so that not a trace of them could be found." (2:35) And then the stone — the stone! — grows. It becomes a mountain. And the mountain fills the whole earth.
The Book of Revelation, the great companion volume to Daniel, knows this moment. In chapter 11, after the seventh angel sounds his trumpet, the elders in heaven fall on their faces and sing: "The kingdom of the world has become the kingdom of our Lord and of his Christ, and he shall reign forever and ever." That is Daniel 2 reaching its conclusion. The stone has become the mountain. The mountain has filled the earth.
Faithful Under Fire Sermon One Daniel 1:1-21 Exile: From Catastrophe to Calling
If we are exiles, resident aliens here while being citizens of the heavenly city, then the most practical book in the Old Testament for this moment is the one we open in this series: the Book of Daniel.
These are the two pillars no Christian can live without: God is sovereign over where we are. God is faithful to meet us with his grace. The exile is within his purpose. The calling comes with provision. The same God who placed Daniel in Babylon gave Daniel everything he needed to serve there for the rest of his life.
Faithful Under Fire - An Introduction to Daniel
Daniel was an exile. He did not comply. But neither did he withdraw, rage, or despair. He received grace to maintain his faith and grace to love and serve even those who hated him. He learned Babylon's language. He served in the government. He contributed to its flourishing. And he prayed three times a day, with his windows open toward home. That posture — present in Babylon without becoming Babylonian, engaged without being absorbed, hopeful without being naive — is the posture this series is about.
Prisoner Number 16670
At least 1.5 million Jews perished in Auschwitz and its neighboring camp, Birkenau. The evidence indicates many more than that died. Hundreds of thousands of others were murdered under the terrifying efficiency of these Nazi death and labor camps. This is the brief story of one of those others, and the difference that one life offered up in love made in the life of another.
A New Command: The Mark of the Authentic Christian - My Maundy Thursday Memo to Spanish River Church and Friends
The Church has never been a gathering of the already-perfected. It has always been, and will always be on this side of eternity, a hospital for sinners, a ragged collection of people who sometimes betray and sometimes deny, who struggle with pride and cowardice and all manner of ordinary human failure. If you have spent any time in a church — including this one — you already know this. It is not news.
But here is what is news. Here is what cuts against the darkness of that room like a lamp in a window.
Jesus, knowing all of it — the betrayal already in motion, the denial already forming in Peter's chest, the scattering that was only hours away — Jesus gave them the mandate anyway. Love one another as I have loved you.
Fire on the Mountain, Commandments Nine and Ten: Hosanna to the Son of WHO???
Passover week has just begun. A stranger is riding into Jerusalem, and exuberant crowds are hailing his arrival. They spread their cloaks on the road and cried out a name that ought to stop us cold: "Hosanna to the Son of David!"
That name. How?
How can the Messiah bear the name of an adulterer and a murderer?
How do we sing his Psalms?
How do we treasure his prophetic words?
How does any of this hold together?
Fire on the Mountain: the Seventh Commandment
“And that is what some of you were…” (1 Corinthians 6:11)
The Corinthians had messy lives. Sexual sin, broken relationships, distorted desires. Paul names it. He doesn’t pretend it’s fine.
But then comes one of the most important words in the Bible: “But.”
“But you were washed. You were sanctified. You were justified in the name of the Lord Jesus Christ and by the Spirit of our God.”
That one word changes everything.
The gospel doesn’t ignore the past. It interrupts it. It breaks into the present with a future we didn’t earn and don’t deserve.
St. Patrick, a Morning Prayer, and Saving Civilization
Since my middle name is Patrick and my last name is Cassidy (or “O’Cassidy” as it once was styled) - a name from the misty peatlands, drumlins, streams, and forests of Co. Fermanagh - I hope you’ll forgive me this St. Patrick’s Day for commending to you a book with the title “How the Irish Saved Civilization”, by Thomas Cahill… and a morning prayer to accompany your green fashions today.
Fire on the Mountain, the Sixth Commandment - Murder Not!
The sixth commandment is not merely about avoiding violence. It calls God’s people to protect and cultivate life. A murderous philosophy motivated the Nazi regime, but it has its contemporary co-belligerent in the work of Princeton ethicist Peter Singer. His radically anti-Christian view that belittles the idea of humans as God’s image bearers, a view he refers to as “speciesism”, leads him to conclude that the newly born infant is not fully human - only potentially so, that a human infant is no different than a pig and must prove to the parents that he’s worthy of life. This massive deception is creeping into mainstream thinking and affects the Church as well. Against it, we affirm a Biblical anthropology and choose life.
Fire on the Mountain. The Fifth Commandment, Part Two: Raising Children in the Paideia of the Lord
Paideia means more than discipline. It refers to whole-life formation. The shaping of a person’s values, loves, habits, instincts, and imagination. It’s the deep work of enculturation.
Paideia of the Lord: A Vision for Kingdom Culture in Our Homes
Paul takes a word that once aimed at forming citizens for the empire and redirects it toward forming heirs of the kingdom, the citizens of heaven on earth.
Fire on the Mountain: Honor Your Father and Your Mother
The Ten Commandments are not thin rules. They are seeds. Each contains an entire moral world inside it.
Just as the command not to bear false witness includes gossip, slander, flattery, and manipulation, so the command to honor father and mother stretches far beyond childhood obedience. The bare command does not exhaust its meaning.
It will take time to unpack even the surface issues. There are two main angles here.
First, honor and respect. That is the view from the child’s position, or more broadly, from anyone under authority.
Second, “raising” up. Paul uses the word paideia in Ephesians 6. It means discipline, training, and formation. That is the view from the parent or authority position.
Honor and formation. These two realities are central to how the kingdom of God becomes visible in the world.
Ash Wednesday Homily
“I dwell in the high and holy place, and also with him who is of a contrite and lowly spirit.”
The word contrite means crushed. Broken. Not theatrically ashamed. Not self-hating. But pierced. Awakened. Humbled.
There is a world of difference between shame and contrition.
Shame says: I am worthless, so I hide. Shame looks for fig leaves and weaves a new runway-worthy clothing line.
Contrition says: I am sinful, so I come. No more hiding. No more pretending. No more minimizing. I can’t save myself; I must have a Savior.
Ash Wednesday is not about groveling before a reluctant God. It is about coming honestly before a gracious one.
Notice the promise: He dwells with the contrite.
Not tolerates. Not endures. Dwells.
The high and holy God makes His home with the humble.

An Interpretive Manifesto for Reading and Teaching Revelation
Over the years, I’ve been asked many times to preach the Book of Revelation and, while I have often preached from it, I’ve never preached through it. There are a lot of reasons for that, not the least being the weird sensationalism that some people bring to the book. But I find myself considering doing so now, maybe in the winter of 26-27, though I’m not sure if I would do so on Sunday morning or a new worship service in the evening. This article simply lays out how I approach Revelation.
