To be the church is to confess, as Peter did, that Jesus is the Christ, the Son of the living God. This confession is not merely an intellectual agreement but a declaration that Jesus is the answer to every longing, the King who overcomes death, and the Savior who brings life. The heart of Christianity is not about politics, culture, or even religious tradition—it is about who Jesus is. Each person must answer the question, “Who do you say I am?” for themselves, and that answer shapes eternity, purpose, and hope. If you believe, it is a gift from God, a miracle of grace that opens blind eyes and revives dead hearts. [20:21]
Matthew 16:15-17 (ESV)
He said to them, “But who do you say that I am?” Simon Peter replied, “You are the Christ, the Son of the living God.” And Jesus answered him, “Blessed are you, Simon Bar-Jonah! For flesh and blood has not revealed this to you, but my Father who is in heaven.”
Reflection: Who do you truly say Jesus is in your heart today, and how does that confession shape the way you live and make decisions right now?
The certainty of the church’s growth and endurance does not rest on human effort, but on the promise and power of Jesus Himself. He declares, “I will build my church,” assuring us that, despite opposition, setbacks, or even our own failures, His church will be established and will flourish. This promise gives hope in the face of darkness, discouragement, or national tragedy, because Jesus is actively calling forth His people and expanding His kingdom. Our role is to trust in His faithfulness and participate in what He is already doing, knowing that the outcome is secure in His hands. [36:36]
Matthew 16:18 (ESV)
And I tell you, you are Peter, and on this rock I will build my church, and the gates of hell shall not prevail against it.
Reflection: In what area of your life or ministry do you need to trust that Jesus is the one building and sustaining, rather than relying on your own strength or control?
The church is not a building, a program, or a possession of any leader or group—it is the people who belong to Jesus, bought with His blood, known intimately by Him, and cherished as His own. He knows each member by name, understands every need, and claims His people as His bride and body. This belonging is deeply personal and secure; no matter our failures or doubts, if we are in Christ, we are His. Our identity and unity as a church flow from this truth, and our mission is to live as those who are loved and sent by Him. [39:10]
John 10:27-29 (ESV)
My sheep hear my voice, and I know them, and they follow me. I give them eternal life, and they will never perish, and no one will snatch them out of my hand. My Father, who has given them to me, is greater than all, and no one is able to snatch them out of the Father’s hand.
Reflection: How does knowing you belong to Jesus—fully known and fully loved—change the way you approach your relationships and your role in the church today?
Jesus’ vision for His church is not limited by ethnicity, language, or geography; it is a gathering of people from every tribe, nation, and tongue, united by the confession that Jesus is the Christ. The church is a foretaste of the great multitude in Revelation, standing before the throne, worshiping the Lamb together. This diversity is not accidental but central to God’s plan, and it calls us to embrace, love, and reach out to all peoples, reflecting the heart of God for the world. Our mission is to invite more into this family, celebrating unity in Christ amid beautiful diversity. [41:43]
Revelation 7:9-10 (ESV)
After this I looked, and behold, a great multitude that no one could number, from every nation, from all tribes and peoples and languages, standing before the throne and before the Lamb, clothed in white robes, with palm branches in their hands, and crying out with a loud voice, “Salvation belongs to our God who sits on the throne, and to the Lamb!”
Reflection: Who in your neighborhood, workplace, or city might feel like an outsider, and how can you intentionally welcome them into the family of God this week?
While Jesus will build His church with or without us, He invites us into the joy and privilege of participating in His mission—praying, serving, giving, and even going to help plant new churches and reach new people. The call is not just for a select few but for every believer to discern their role, whether through prayer, practical involvement, generosity, or simply being faithful where God has placed them. Even small acts of faithfulness can have generational impact, and God delights to use ordinary people for extraordinary purposes. The question is not whether God will accomplish His mission, but whether we will join Him in it. [44:48]
Romans 12:4-8 (ESV)
For as in one body we have many members, and the members do not all have the same function, so we, though many, are one body in Christ, and individually members one of another. Having gifts that differ according to the grace given to us, let us use them: if prophecy, in proportion to our faith; if service, in our serving; the one who teaches, in his teaching; the one who exhorts, in his exhortation; the one who contributes, in generosity; the one who leads, with zeal; the one who does acts of mercy, with cheerfulness.
Reflection: What is one concrete step you can take this week—whether in prayer, service, giving, or encouragement—to participate more fully in God’s mission through the church?
The story of Sunset Church is a story of God’s faithfulness through generations, beginning with Cai Leong Li’s vision in 1905 to plant a church in San Francisco’s Chinatown. That vision, passed down through the decades, led to the founding of our own church in the Sunset district, as people moved out of Chinatown and sought to reach their neighbors with the gospel. Our heritage is rooted in the faithfulness of those who came before us, but it is not static—God’s mission is always expanding, calling us to reach all peoples, not just those who share our background or language. The heart of our calling is to glorify God by making gospel-transformed disciples of all people in our city and beyond.
Church planting is not just a historical footnote; it is at the very heart of the Great Commission. Every one of us has been touched by the faithfulness of those who started churches, whether directly or indirectly. Our church has supported church planting both locally and globally, through missionaries and partnerships with new congregations. Yet, I believe God may be calling us into a new season of initiating church planting ourselves—sending people, resources, and prayer to places that need the gospel, just as our spiritual ancestors did.
But before we talk about strategies or plans, we must return to the foundation: Jesus’ words in Matthew 16, “I will build my church.” The church is not a building or a program; it is a gathering of people who confess that Jesus is the Christ, the Son of the living God. The “I” in that promise is the Creator, Sustainer, and King—Jesus himself. He alone builds the church, and he does so with certainty. Our role is not to manufacture results, but to faithfully participate in what he is already doing.
Jesus’ promise is deeply personal: “my church.” We belong to him, intimately known and loved. The church is his bride, his body, gathered from every tribe, nation, and tongue. And his promise is powerful: “the gates of hell shall not prevail against it.” Death itself cannot overcome what Jesus is building. Our hope, even in the face of darkness or uncertainty, is anchored in his victory.
So, what is our response? Pray for clarity, boldness, and faithfulness. Participate in the life of the church now, not just as consumers but as contributors. Give generously, knowing that our resources are tools for God’s mission. And be open to the possibility that God may call us to take new steps in church planting, trusting that he will build his church—whether through us or in spite of us. What a privilege to be part of his work.
Matthew 16:13–18 (ESV) — 13 Now when Jesus came into the district of Caesarea Philippi, he asked his disciples, “Who do people say that the Son of Man is?”
14 And they said, “Some say John the Baptist, others say Elijah, and others Jeremiah or one of the prophets.”
15 He said to them, “But who do you say that I am?”
16 Simon Peter replied, “You are the Christ, the Son of the living God.”
17 And Jesus answered him, “Blessed are you, Simon Bar-Jonah! For flesh and blood has not revealed this to you, but my Father who is in heaven.
18 And I tell you, you are Peter, and on this rock I will build my church, and the gates of hell shall not prevail against it.”
This is probably the most important question ever asked. And it will be the most important answer to which you will ever give any question in your life. Who do you say Jesus is? Your answer to that question determines your eternity. It determines your present. It determines everything about your life. What do you really believe about Jesus? [00:20:21] (29 seconds) #FaithIsAGiftFromGod
If you believe Jesus is Lord and Savior, the Christ, it is always a gift of God. You didn't figure it out on your own. Yes, you played a role in exploring. You played a role in asking questions. It's not like you're a machine. And yet fundamentally, anyone who comes to faith, it is a supernatural thing. It is a miracle. Anyone comes to believe because it comes from the father opening blind eyes, opening dead hearts, giving you the Holy Spirit, bringing you back to life when you were dead man walking, dead woman walking. It is a gift. [00:24:08] (42 seconds) #JesusIsTheAnswerToAll
Everyone's looking for something. Everyone has a problem. They need an answer to everyone wants something, whether they can articulate it or not. Jesus is that answer. You have disorder in your life from illness, from relationships, from economic vocational problems. Jesus is the answer. You are facing death, the enemy that levels every single person on earth, whether you're young or old, rich or poor, it does not matter. Death, death is the greatest enemy. You want an answer to that? Beyond that, that no one knows? Jesus is the answer. He is the point. He is the last word. He's it. He's everything anyone has ever been waiting for. [00:26:15] (42 seconds) #ChristIsTheLivingGod
He says he will build it. Notice this is said with certainty. It will happen. He didn't say, I may build my church. I may or may not build my church, depending on this particular circumstance, if it goes my way or no. He says, I will build my church. No ifs or buts. It's a promise of certainty. And Jesus does not lie. So his church will be built. Jesus built the church. It's a certainty. [00:35:14] (37 seconds) #HopeInJesusPromise
You want to know how we can have hope in the face of national evil, personal evil, personal disappointment. It's because Jesus promises to build his church. He promises to return and call forth those who are his. He promises to write every wrong ever done in the world. [00:36:48] (23 seconds) #KnownAndLovedByChrist
He knows your name. He knows how many hairs are on your head. Even Abe's. He knows how many hairs are on his head. He knows. He knows. You are his if you are in Christ. He bought you with his own blood. You are his bride. We are his body. [00:38:00] (35 seconds) #ChurchIsPeopleNotPlace
The church is not a building. Whether or not we have the buildings that we have or not does not matter. It does not make us Sunset Church. Sunset Church is because of you. The various iterations of us as a people that gather together, it's not based upon even this particular location. Whether we meet in the park or during COVID, we met online, it doesn't matter. When we gather together, we are the people who confess Jesus is the Christ and we commit to one another and we live on mission for Jesus. This makes us the church. [00:40:15] (30 seconds) #UnitedInDiversityThroughChrist
Diverse in language, diverse from place, diverse from peoples and tribes, from political groups, from every place of division you can imagine, diversity there, and yet united around Jesus being the Christ, the son of the living God, and he is the one who saves. That is the church. [00:41:19] (24 seconds) #JesusConquersDeathAndHell
