Theme: Knowing Jesus Rightly Changes Everything

Introduction

Jesus asks two questions in this passage, and they’re not the same question. First, he asks the disciples who people say the Chosen One is. Then: “But who do you say I am?” The first question is easy. It costs nothing to report what other people think. The second question is different. It’s personal. It demands an answer each of us has to own. And Jesus still asks it today — not “what does your church say,” not “what did you learn in Sunday school,” but who do you say I am? This morning, two points from this text: Confession reveals Christ, and Confession builds the church.

I. Confession Reveals Christ (vv. 13–17)

Jesus takes the disciples to Caesarea Philippi — a region soaked in pagan worship, with shrines to Greek gods and a great rock face believed to be a gate to the underworld. It’s a strange place to ask a theology question, but maybe that’s the point. Surrounded by every competing answer to “who is God,” Jesus asks the question directly.

The disciples report the popular opinions: John the Baptist, Elijah, Jeremiah, one of the prophets. All flattering. All wrong. Then Peter answers: “You are the Christ, the Son of the living God” (v. 16).

Notice what Jesus says next: “Blessed are you, Simon son of Jonah! For flesh and blood has not revealed this to you, but my Father who is in heaven” (v. 17). Peter didn’t figure this out. It was given to him.

This matters because it tells us something about how anyone comes to know Jesus rightly. Right belief about Christ isn’t the product of cleverness, upbringing, or good guessing. It’s revelation. That should humble us and free us at the same time. Humble us, because none of us think our way to Christ — we receive this truth. Free us, because it means knowing Jesus isn’t reserved for the sharpest minds in the room. It’s a gift God gives to whoever will receive it.

So the question comes to us the way it came to Peter: not “what have you heard about Jesus,” but “who has God shown you Jesus to be?” A vague, generically respectable Jesus — good teacher, wise moral example — is still just “one of the prophets.” The real confession is sharper: the Christ, the Son of the living God. Fully God, sent to save. That confession isn’t optional decoration on faith. It is the faith.

II. Confession Builds the Church (vv. 18–20)

Jesus responds to Peter’s confession with a promise: “You are Peter, and on this rock I will build my church, and the gates of hell shall not prevail against it” (v. 18).

Christians have long debated what exactly “this rock” refers to — Peter himself, or the confession Peter just made. But notice: Peter is never called the foundation elsewhere in Scripture — Christ is (1 Corinthians 3:11). What seems clearest from the context is that the rock is the truth Peter just spoke aloud: that Jesus is the Christ, the Son of the living God. That confession is the bedrock on which everything Jesus builds stands.

This means the church was never meant to be built on charisma, cleverness, or the strength of any single leader — not Peter, not any pastor, not any of us. It’s built on a confessed truth about who Jesus is.  That should encourage anyone who feels the church is fragile right now. It isn’t built on our competence. It’s built on Christ, and what’s built on that foundation cannot be overrun.

Then Jesus gives Peter the keys of the kingdom — the authority, shared later with all the disciples, to proclaim what is bound and loosed by the truth of the gospel. And the disciples are told to tell no one yet that Jesus is the Christ (v. 20) — not because it’s untrue, but because the time isn’t right; the cross must come first. The full meaning of “Christ” can’t be understood apart from a Messiah who suffers and dies for all people.

Conclusion

Two questions still hang in the air this morning. Who do people say Jesus is? You could survey a hundred opinions. But who do you say Jesus is? Your answer to that question isn’t private trivia. It’s the rock you’re standing on, or the sand. Peter’s confession was a gift given to him — and it’s offered to each of us the same way. Not earned. Received.

So: who do you say Jesus is?

Amen.
