Guerrilla Christianity

Pastor R. Bret Walker reflects on Matthew 11 and the true meaning of freedom—not political liberty, but the liberation Christ gives to those burdened by sin. Using personal testimony and imagery from Pilgrim’s Progress, he shows how sin accumulates like stones in a backpack until Christ removes the weight entirely. Jesus exposes the blindness of “this generation,” reveals the Father to the humble,...

Pastor R. Bret Walker reflects on Genesis 22 and Abraham’s testing on Mount Moriah, showing how God both calls His people to difficult obedience and graciously provides what they need. Abraham’s willingness to offer Isaac foreshadows the Father offering His only Son, Jesus, as the true Lamb of God. The parallels—Moriah, the wood, the thorns, the three‑day motif—reveal God’s sovereign plan pointing...

Pastor R. Bret Walker explores Genesis 21 and the story of Hagar and Ishmael to reveal the contrast between the son of the slave and the son of the free. On Father’s Day, he reflects on earthly fathers—good, absent, or broken—and points listeners to the perfect Father who never abandons His children. God hears Ishmael’s cry, provides for him in the wilderness, and promises to make him a great nati...

In this third message of the After the Fall series, Pastor R. Bret Walker explores God’s astonishing promise to Abraham and Sarah—an elderly couple who laugh at the idea of bearing a child. Yet God responds, “Is anything too hard for the LORD?” Through this encounter at the oaks of Mamre, Pastor Walker highlights God’s faithfulness, His perfect timing, and His power to accomplish what seems imposs...

In this second message of the After the Fall series, Pastor R. Bret Walker traces humanity’s decline after Eden and introduces Abram as God’s surprising new beginning. God calls Abram to leave everything familiar and promises, “In you all the families of the earth shall be blessed.” Pastor Walker explores Abram’s obedience, his fears, and God’s unwavering faithfulness—even when Abram falters. This...

In this opening message of the After the Fall series, Pastor R. Bret Walker explores creation “before anything existed except God alone,” reflecting on Genesis 1–2 and the perfect world God declared “very good.” Pastor Walker highlights the Trinity at work in creation, humanity made in God’s image, and the original harmony of a world without death or corruption. He connects the third day of creati...

In this Pentecost message, Pastor R. Bret Walker explores what it truly means to be a Spirit‑filled church. Drawing from Acts 2, he highlights six marks of a vibrant congregation: a praying church, a witnessing church, a sent church, a persecuted church, a preaching church, and a baptizing church. Pastor Walker challenges listeners to embrace the work of the Holy Spirit—uniting in prayer, boldly s...

In this penultimate message of the Easter series The Early Church: Lessons from the Book of Acts, Pastor R. Bret Walker explores the Ascension and the calling of the church to be a sent people. Drawing from Acts 1:1–11, he highlights Jesus’ command to wait for the Holy Spirit, the power given to believers, and the mission to witness in ever‑widening circles—Jerusalem, Judea, Samaria, and the ends...

In this message, Pastor R. Bret Walker explores Paul’s sermon at the Areopagus (Acts 17:22–31) as a model for evangelism in a skeptical world. Paul begins with common ground, acknowledges the Athenians’ spiritual searching, and reveals the “unknown God” as the Creator who calls all people to repentance. Pastor Walker challenges believers to recover the courage and clarity of the early church—a pre...

In this message, Pastor R. Bret Walker reflects on the reality of the persecuted church, drawing from Stephen’s martyrdom in Acts 7. Stephen, “full of the Holy Spirit, gazed into heaven and saw… Jesus standing at the right hand of God,” even forgiving his executioners as he died. The sermon highlights how persecution has historically strengthened the church, noting that “almost 400 million Christi...

In this message, Pastor R. Bret Walker explores what made the early believers in Acts 2 a truly united church. They “devoted themselves to the apostles’ teaching… the fellowship… the breaking of bread and the prayers,” a pattern that shaped their shared life and mission. Their generosity, joy, worship, and mutual care led to “favor with all the people,” and as a result, “the Lord added to their nu...

Guerrilla Christianity – “The Baptizing Church” Pastor R. Bret Walker explores Acts 2 and the early church’s explosive growth as a baptizing church. Peter’s call to “Repent and be baptized… for the forgiveness of your sins” becomes the heart of the message, showing baptism as a means of grace and a sign of God’s claim on his people. The sermon urges believers to embrace repentance, proclaim Christ...

Pastor R. Bret Walker launches a new series, The Early Church: Lessons from the Book of Acts, by exploring Acts 2 and the bold witness of Peter at Pentecost. This episode, The Witnessing Church, calls believers to embrace the same Spirit‑empowered mission: proclaiming what Christ has done, sharing personal testimony, and moving from merely welcoming to actively inviting others to faith. The early...

On Easter Sunday, Pastor R. Bret Walker concludes the “Letters from God” series with Colossians 3:1–4, urging believers to live from the reality that they have been raised with Christ. Paul’s “if” is better understood as “since”—a call to seek what is above, not the fading pursuits of earth. The sermon contrasts temporary treasures with the eternal satisfaction found only in God, reminding us that...

In this Easter Sunrise sermon on John 20:1–18, we stand with Mary, Peter, and John at the empty tomb and hear the risen Jesus speak Mary’s name. The resurrection is more than a temporary revival—it is Christ’s victory over sin and death and the promise of everlasting life. Because Jesus lives today, our faith is not in vain, and the grave will not have the final word. The risen Savior calls His pe...

On Guerrilla Christianity, this episode features the sermon “We Believe” (Letters from God, Part 7) for Palm/Passion Sunday, centered on Philippians 2:5–11. The message traces Christ’s journey from eternal glory to willing humility: Jesus, fully God, “emptied himself,” took the form of a servant, and obeyed to the point of death on a cross. Paul’s hymn is explored as an early creed with a chiastic...

In this Lenten message from Romans 8:6–11, Pastor R. Bret Walker draws a hard line between two ways of living: life in the flesh and life in the Spirit. Using Scripture, personal story, and unapologetic clarity, he argues there is no middle ground—only life or death. To live in the Spirit is to love God and neighbor, reject the idol of self, and receive the resurrecting power of Christ through the...

Children of Light calls believers to live visibly transformed lives in a world shaped by darkness. Drawing from Ephesians 5:8–14, this sermon explores how faith in Christ moves us from spiritual blindness into the revealing light of God. Walking in the light means discernment, fruitfulness, and accountability—not hiding sin, but exposing it so healing and renewal can begin. Through Paul’s teaching...

In this episode of Guerrilla Christianity, we confront the radical truth of reconciliation. Drawing from Romans 5:1–11, this sermon declares that peace with God isn’t earned—it’s given. While we were still sinners and enemies, Christ died for us, reconciling us to God through the cross. Suffering, faith, and hope are reframed in light of God’s relentless love. Like a tree covered in yellow ribbons...

In this episode of Guerrilla Christianity, we confront one of the most radical truths of the gospel: we are justified by faith, not by works. Drawing from Romans 4, we explore how Abraham was declared righteous simply because he believed God—not because he earned it. Grace is not a wage; it’s a gift. Faith itself is God’s work in us, opening our eyes to Christ and anchoring us in His promise. This...
