Guerrilla Christianity

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 church grew through courageous witness — and we are called to do the same today.

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 our lives are “hidden with Christ” and secured by His resurrection. Because Christ is our life, we live with hope: He is risen, and He will return in glory.

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 people to worship with joy and to share the gospel boldly, since this good news is too important to keep to ourselves.

 

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 structure—descent into humiliation, then resurrection and exaltation—culminating in every knee bowing and every tongue confessing Jesus Christ as Lord.

 

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 Holy Spirit. The gospel confronts us with a choice. Guerrilla Christianity chooses life.

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 and John Wesley’s model of Christian accountability, we’re reminded that authentic discipleship is communal, courageous, and costly. Awakening from spiritual sleep, we live not for ourselves, but as people shaped—and sent—by Christ’s light. #ExposeTheDarkness

 

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, the cross stands as unmistakable proof: forgiveness is real, grace is abundant, and reconciliation is already accomplished in Jesus Christ.

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 episode challenges both legalism and empty belief, calling us to trust fully in Jesus alone—the God who brings life from death and calls into being what does not exist.

 

In this episode, The One Man, we unpack Romans 5:12–19 and the radical contrast between Adam and Christ. Through one man’s disobedience, sin and death entered the world; through one man’s obedience, grace and life are offered to all. This sermon explores why sin runs deeper than rule-breaking, why the Law can’t save us, and why Jesus’ sinless life is essential to salvation. Lent calls us to face the bad news honestly—then cling boldly to the good news: justification, righteousness, and eternal life come as a free gift through Jesus Christ alone.

Guerrilla Christianity dives into The Disciple’s Prayer, an Ash Wednesday sermon exploring Jesus’ model for prayer in Matthew 6. This episode unpacks why prayer isn’t about empty words but humble dependence on God. Walking through the Lord’s Prayer line by line, the sermon highlights adoration, submission to God’s will, daily reliance, forgiveness, and resistance to temptation. Listeners are challenged to see prayer as heart alignment, not performance—and to live as forgiven people who forgive others. This is a call to authentic, daily prayer that shapes disciples for faithful, obedient living before a holy God.
