The Fire You Cannot Contain
Dear brothers and sisters in Christ, there are words in Scripture so raw that we almost hesitate to read them aloud in church. Today we heard one of them.
"You duped me, O LORD, and I let myself be duped." That is Jeremiah, a prophet of God, standing before the Almighty and accusing him of seduction. The Hebrew word is startling. Jeremiah says God overpowered him, tricked him, drew him in with promises and then handed him a life of ridicule and rejection. He preached the truth and got laughter for it. He spoke God's word and became the town joke.
So Jeremiah makes a decision that every one of us has made at some point. He says: I quit. "I will not mention him, I will speak in his name no more."
And then comes the line that has haunted saints for twenty-six centuries. "But then it becomes like fire burning in my heart, imprisoned in my bones; I grow weary holding it in, I cannot endure it."
My friends, that is the heart of our faith today. Following God costs something real. And yet, once he has touched you, you cannot walk away, because his word has become a fire inside you that you cannot put out.
Now look at the Gospel, and you will see the same fire and the same resistance, only this time in Peter.
Just last Sunday, Peter got it magnificently right. "You are the Christ, the Son of the living God." Jesus called him blessed, called him rock, handed him the keys of the kingdom. Today, one paragraph later, that same rock becomes a stumbling stone. "Get behind me, Satan! You are an obstacle to me."
What changed? Jesus began to teach that he must go to Jerusalem, suffer greatly, be killed, and on the third day be raised. And Peter took him aside and said, "God forbid, Lord! No such thing shall ever happen to you."
Notice, brothers and sisters, that Peter is not being malicious. He is being loving. He is protecting his friend. This is what makes his error so instructive for us, because Peter's mistake is the most natural mistake in the world. He wants a Messiah without a cross. He wants glory without Calvary. He wants resurrection without dying first.
Saint Augustine put it with his usual precision. Peter, he said, wanted to correct the Physician who had come to heal him. Peter loved Jesus but was thinking, in Jesus' own words, "not as God does, but as human beings do."
And here is where this stops being ancient history and starts being about us. Because that is our instinct too. We want a Christianity that comforts but never costs. We want the peace of Christ without the surrender that produces it. We want to follow Jesus, but we would prefer he take a route that avoids Jerusalem.
So Jesus says the words that have shaped every saint who ever lived: "Whoever wishes to come after me must deny himself, take up his cross, and follow me."
Dear friends, we must be careful here, because that verse gets misused. Taking up the cross does not mean God wants you to suffer. God is not a Father who enjoys your pain. Pope Benedict XVI explained it beautifully: the Christian is not a masochist. The cross is not suffering for its own sake. The cross is what love looks like when love refuses to stop loving in a world that resists it.
That is why Jeremiah kept preaching. That is why Jesus walked toward Jerusalem. Not because pain is good, but because love that abandons the beloved at the first sign of difficulty was never really love at all.
And what does that cross actually look like for most of us? Rarely martyrdom. Usually something quieter and more daily.
It looks like staying faithful in a marriage that has become hard work rather than romance. It looks like caring for a parent who no longer remembers your name. It looks like refusing to join the conversation at work when it turns cruel, and paying the social price for it. It looks like a young person choosing chastity while their friends laugh, or a business owner losing a contract rather than lie.
It looks like getting up again tomorrow morning and praying, even though last week's prayer felt like talking to a wall.
That is the cross. And Jesus attaches an extraordinary promise to it: "Whoever loses his life for my sake will find it."
This is the great paradox at the center of Christianity, brothers and sisters, and it is not a religious slogan. It is a description of how reality actually works. The person who grasps at life, hoards it, protects it, spends it entirely on themselves, ends up with a small, anxious, shrinking existence. The person who pours life out for God and for others finds it multiplying in their hands.
Every mother in this church knows this. Every person who has sat up all night with a sick friend knows it. You gave yourself away and somehow came back fuller.
Which brings us to Saint Paul in that magnificent second reading. "Offer your bodies as a living sacrifice, holy and pleasing to God, your spiritual worship."
Paul is writing to Christians in Rome who had watched animals sacrificed on altars their whole lives. And he tells them: the sacrifice God wants now is not a lamb on an altar. It is you. Your body. Your time. Your hands, your schedule, your energy, your ordinary Monday.
A living sacrifice, my friends. Which means the sacrifice that gets up off the altar and keeps walking. The sacrifice that continues at the office, in the kitchen, in the hospital room, in the difficult conversation you have been avoiding.
And then Paul gives the command that names our whole struggle: "Do not conform yourselves to this age but be transformed by the renewal of your mind."
That word conform is the key. Conformity happens by drift. Nobody decides to let the world shape their heart. It just happens, one small compromise at a time, one hour of scrolling at a time, until we find ourselves thinking exactly as everyone around us thinks, and we call it common sense, and we have become Peter, telling Jesus that the cross is unnecessary.
Transformation, by contrast, never happens by drift. It only happens by choice, and by grace.
And that grace is on this altar in a few moments. Brothers and sisters, look at what we are about to do. We are about to celebrate the very thing Peter tried to prevent. On this altar, Christ's self-offering, his refusal to save his own life, becomes present among us.
And when you come forward and receive him, he does not merely comfort you. He puts his fire in you. The same fire that burned in Jeremiah's bones. The same fire that finally consumed Peter, who did eventually take up his cross in this very city of Rome.
So here is my invitation this week. Before you leave the church today, name one cross. Just one. One relationship, one duty, one temptation, one sacrifice that you have been taking Jesus aside about and saying, "God forbid, Lord."
Bring it to Communion. Lay it on the altar with the bread and wine. And say quietly, "Lord, I stop resisting. Transform me."
Because the fire he lights in you is one you will never be able to contain. And you will not want to.
Amen.
