The shape of the argument

51 units across exposition, application, illustration, theological claim, and conclusion. The pastor's argument is built from these moving parts.

Pastoral correction · unit #18
"The illustration is explicitly applied. The pastor lists specific categories of daily communication with his wife (kids, forgiveness, help, excitement, health, decisions) and maps each directly onto prayer topics. The application is concrete and actionable."

Illustrations· 10
  1. historical example · unit #4 — Bunyan's Pilgrim's Progress is used to illustrate the concept of 'all-prayer' as a final weapon taken up when other weapons fail. The literary image of Christian forced to put down his sword and take up prayer establishes prayer as essential battlefield equipment.
  2. analogy · unit #8 — Piper's battlefield radio analogy is introduced to replace the Precious Moments image. The radio represents prayer as vital communication with the Commander—rugged, essential, and meant for hard use in combat.
  3. analogy · unit #12 — The battlefield radio analogy is extended to illustrate the consequences of separating Word and prayer. Listening without speaking (Word without prayer) and speaking without listening (prayer without Word) are both dysfunctional and dangerous.
  4. personal story · unit #17 — A personal courtship story illustrates how natural, ongoing communication can become woven into daily life. The analogy models what 'praying at all times' looks like—not rigid ritual but relational checking in with the Lord throughout the day.
  5. personal story · unit #20 — A personal story of the pastor's mother exemplifies focused, intentional prayer. Her consistent early-morning practice and the family's respect for that time models how to create protected space for alert, focused prayer.
  6. personal story · unit #22 — A parenting illustration contrasts two types of toddlers: those who persist until they open a door and those who give up after minimal effort. The analogy is explicitly applied to prayer—many Christians give up after one or two prayers instead of persevering.
  7. personal story · unit #25 — A testimony of a pastor and his wife who prayed for years for her mother's salvation without visible results. They persevered through discouragement and difficulty, and finally at the end of her life, she came to Christ. The story demonstrates the value of persevering in prayer even when God's answer is delayed.
  8. personal story · unit #32 — A testimony of Sharon Withers, an older widow who came to the church building during the week to physically walk through it and pray for families, the children's ministry, and the neighborhood. The story models what praying for all the saints looks like in practice and convicts the pastor of his own prayerlessness despite being at the building constantly.
  9. personal story · unit #39 — A contemporary illustration of a US embassy explains the ambassador metaphor. Key points: embassies are sovereign territory, attacking them is an act of war, and their mission is not to hide but to represent their home country's culture to the surrounding nation.
  10. personal story · unit #45 — A vulnerable personal story of the pastor's exhaustion and emptiness before visiting his hospitalized father. Feeling depleted, he stopped in the hospital chapel to pray for 10 minutes. The act of pouring out his heart to the Lord in prayer brought clarity, energy, and spiritual awakening. The story powerfully illustrates the necessity of prayer for all of life—even in moments of pastoral ministry.
Theological claims· 4
  1. Prayer is not a fragile, precious, optional practice but a rugged weapon necessary for spiritual warfare. unit #5
  2. Paul does not permit the division of Christians into 'Word people' or 'prayer people'—both Word and prayer must be integrated in every believer's life. unit #11
  3. God answers every godly prayer in one of three ways: 'Yes, now,' 'Yes, soon, but not now,' or 'No, because I have something better'—never arbitrary refusal. unit #26
  4. Every church is an embassy of God's kingdom, a foretaste of the age to come, called both to invite the world in to see God's grace and to go out as ambassadors representing that kingdom. unit #40
Quotations· 5
"Thus Christian went on and I heard him here sigh bitterly. For besides the danger mentioned above, the pathway here was so dark that oftentimes when he lifted up his foot to go forward, he knew not where or upon what he should set it next. About the midst of this valley, I perceived the mouth of hell to be, and it stood also hard by the wayside. And now, thought Christian, What shall I do? And ever and anon the flame and smoke would come out in such abundance with sparks and hideous noises, things that cared not for the Christian's sword as did Apollyon, this demon he'd fought before, that he was forced to put up his sword and betake to himself another weapon called all prayer." — John Bunyan (unit #4)
"The power of prayer was not given to the church to win comforts, but to wield a weapon." — John Piper (unit #28)
"What has become clear to me in recent days is that many of our problems with prayer and much of our weakness in prayer comes from the fact that we are not all on active duty, and yet we still try to use the transmitter. We have taken a wartime walkie-talkie and tried to turn it into a civilian intercom." — John Piper (unit #28)
"Preach the gospel. If necessary, use words." — Attributed to St. Francis of Assisi (incorrectly) (unit #34)
"When Isaiah called the people of God to arise and shine, it was because, quote, 'Your light has come and the glory of the Lord has risen upon you.' This was no frustrated outburst pushing them to get up and get on with it, but a promise that amidst the darkness covering the world, His glory may be seen upon you. As God shines upon His beloved redeemed people, so He will shine out from us." — Hames and Reeves (unit #48)

0 · The opening welcome establishes the setting, introduces the preacher, orients the congregation to the biblical text (Ephesians 6), and signals that this is the concluding message in the Ephesians series

All right, well, welcome. Uh, if you're new here, my name is Ricky, as Alex said, and I am so excited to open up the book of Ephesians with you guys this morning. So if you have a Bible, open to the book of Ephesians chapter 6. If you don't have a Bible, that's totally fine. We've got one available on the back table for you. This is a great safe place to learn what the Bible says about all kinds of things, and we are just finishing our study of Paul's letter to the Ephesians.

1 · This unit recaps the broad sweep of Ephesians, characterizing it as a 'grace seminar' covering spiritual blessings, reconciliation, unity, marriage, parenting, and work, and sets up the surprising turn Paul makes at the end

And last weekend we talked about the armor of God. And maybe for you it felt like Paul has been doing this great sort of weekend seminar about grace throughout the letter to the Ephesians. He talks about all the spiritual blessings we have in Christ. He talks about how God's grace has come to us and reconciled us and made us alive. He's talked about unity in the church. He's even talked about marriage and parenting and work, and you're kind of ready for Paul to wrap up the seminar and say, 'Okay, this has been a great time,' and, you know, head back. We're gonna leave the mountains and this retreat and go back to normal life.

2 · This unit uses vivid imagery to capture the jarring shift in Ephesians from teaching to warfare, establishing that the Christian life is fundamentally a fight whether we like it or not

And instead, it's like he hits a button and all of a sudden the lights dim and maps begin to be unfolded and war plans begin to be unfolded. And Alec is all of a sudden going up and down the aisles, handing out flak jackets. And people are saying, 'I'm just here for the marriage seminar.' He's like, 'Yeah, yeah, I know. Here, take this.' And all of a sudden we're taking people, you know, we're handing out weaponry and you think, 'Okay, I signed up for the wrong seminar. How did I get here?' And yet this is exactly how God inspired Paul to end this letter to the Ephesians. He sums up the Christian life you've been learning about as a fight. And whether or not you wanna be involved in a fight, you are involved in a fight as a Christian. And so Paul gives us the armor of God for that fight. And yet there is one last piece of this spiritual battle that we did not cover last week that we will take up this week. One more weapon to put in our arsenal in the Christian life, perhaps the most important of all.

3 · The primary text is read aloud, focusing on Ephesians 6:17-20, which introduces prayer as the final weapon in the armor of God and includes Paul's request for prayer for bold gospel proclamation

So Ephesians chapter 6, and as we read, let's remember this is God's Word. We'll pick it up in verse 17. And take the helmet of salvation and the sword of the Spirit, which is the Word of God, praying at all times in the Spirit with all prayer and supplication. To that end, keep alert with all perseverance, making supplication for the saints, and also for me, that words may be given to me in opening my mouth boldly to proclaim the mystery of the gospel for which I am an ambassador in chains. That I might declare it boldly as I ought to speak. This is God's Word.

4 · Bunyan's Pilgrim's Progress is used to illustrate the concept of 'all-prayer' as a final weapon taken up when other weapons fail

Well, there is a wonderful passage in John Bunyan's Pilgrim's Progress that I want to read to you to open. If you never read the Pilgrim's Progress, it has some old language, but it is well worth reading. It turns the journey of a Christian in everyday life into this long journey of this man aptly named Christian, or Christian in El Paso. And he begins this long journey and he is equipped with armor and he has many battles to fight and he's headed toward this heavenly city. And along the way, he faces many dangers. And there's a particular passage that I think is relevant here as Christian walks past the very mouth of hell. It says, Bunyan writes this, 'Thus Christian went on and I heard him here sigh bitterly.' 'For besides the danger mentioned above,' meaning all the other dangers that he has just talked about, 'the pathway here was so dark that oftentimes when he lifted up his foot to go forward, he knew not where or upon what he should set it next. About the midst of this valley, I perceived the mouth of hell to be, and it stood also hard by the wayside.' And now, thought Christian, 'What shall I do?' And ever and anon the flame and smoke would come out in such abundance with sparks and hideous noises, things that cared not for the Christian's sword as did Apollyon, this demon he'd fought before, that he was forced to put up his sword and betake to himself another weapon called all prayer. Now, in the text, you can't see this, but in the text, Bunyan hyphenates the words all and prayer together to be one word, all prayer. He says even when the sword of the Spirit doesn't seem to be effective, he takes all prayer, this last weapon, up.

5 · This unit contrasts popular cultural conceptions of prayer (fragile, sentimental, safe) with Paul's battlefield understanding

And often we don't think of prayer in the same category as weaponry. I don't know about you, but I grew up in kind of the Christian environment, and I grew up with Everybody's favorite Precious Moments figurines. Does anybody remember Precious Moments? These, I don't even know how to describe them. They're these little adorable, almost like cartoon-like characters in scenes like the nativity. And they had these big puppy dog eyes, you know, and everything was very precious. And they're made out of, weren't they made out of like, not porcelain, but some kind of ceramic of some kind? Yeah, ceramic, yeah. So they're made out of ceramic. So they're very fragile. So you don't play with them, you put them on a shelf. And I remember the one classic Precious Moments figurine was the little praying boy or girl, you know. And they had, I don't know, for some reason, if I remember right, they had not like normal pajamas, they had like 1920s, like dress pajamas that they used to put kids in. And the kid is, he has his little hands folded and his little eyes like this, oh, he's just praying. And you just think that's prayer, prayer is, It's a precious moment with the Lord and it's right there and it's very porcelain ceramic and it's beautiful. And yet Paul smashes that in a sense and he says, 'No, prayer is a weapon. Prayer is for the battlefield. Prayer is not for these quiet, beautiful, precious moments.' Although I'm sure if you have those moments with the Lord, that's wonderful. But Paul is talking about prayer here as a weapon, necessary for the battlefield.

Small-group discussion

6 questions for your group this week

  1. In Ephesians 6:17-20, Paul calls prayer 'the weapon of all-prayer' and describes it as essential spiritual warfare equipment—not optional practice. What shifts in your understanding of prayer when you think of it as a weapon rather than a comfort?
    Ephesians 6:17-20
    → Can you name one area of your life right now where you're facing resistance—relationally, spiritually, vocationally—and describe what it might look like to wield prayer as a weapon in that space rather than waiting until things are peaceful?
  2. The sermon emphasizes that Paul does not divide believers into 'Word people' and 'prayer people'—both Scripture and prayer must be integrated. How do you currently relate these two practices? Where, if anywhere, do you find yourself leaning more heavily into one than the other?
    → What would it look like in your daily rhythm to let Scripture and prayer inform each other—to pray the Bible and study the Bible prayerfully?
  3. Paul's central prayer request in verses 18-20 is not for comfort or blessing but for boldness to proclaim the gospel and for the advance of God's kingdom. When you pray for yourself, your family, or your church, how often is kingdom advancement and gospel proclamation at the center? What does that reveal?
    Ephesians 6:19-20
  4. The sermon teaches that God answers every godly prayer in one of three ways: 'Yes, now,' 'Yes, soon, but not now,' or 'No, because I have something better.' How does this framework change the way you interpret unanswered prayers in your own life or in the lives of people you love?
    → Can you think of a prayer God seemed to answer with 'No, because I have something better'? How did you recognize His wisdom in that refusal?
  5. Paul models praying persistently for the saints and for the advance of God's kingdom even while imprisoned. The sermon notes that Paul views his chains not as an obstacle to gospel work but as the God-given context for faithfulness. What is a difficult circumstance you're in right now, and how might Paul's example invite you to pray differently about it—not for escape, but for kingdom faithfulness within it?
  6. Cross of Grace is called to be an embassy of God's kingdom in El Paso—both inviting our city into the foretaste of God's grace and going out as ambassadors representing that kingdom. As you think about your own neighborhood, workplace, or family, who needs to see and hear that embassy this week? How will you pray for that person or that place?
    Isaiah 60:1-3
    → What is one specific, concrete action you could take alongside that prayer—a conversation, an invitation, a gesture of grace—that embodies the kingdom you're praying for?

Daily readings · Monday–Friday

5-day reading plan

This week we learn to wield prayer as the rugged weapon God has given us—not a fragile practice, but a battle-tested instrument for advancing his kingdom in our city and world.

Monday Ephesians 6:17-20

Paul frames prayer at the end of his armor passage not as an afterthought but as the weapon that deploys all other armor. When we pray, we are not retreating into quiet sentiment—we are taking up arms against the real spiritual opposition we face. The ruggedness of prayer lies in its persistence, its specificity, its refusal to accept defeat.

Tuesday Luke 18:1-8

Jesus tells us to pray always and not lose heart, teaching through the widow's relentless petition that our God is not reluctant to hear us but eager to answer. The widow's shamelessness—her refusal to accept the judge's indifference—is the posture Jesus commends to us in prayer. When we pray for our city, for the gospel, for the saints, we pray not as suppliants hoping to be noticed but as children of the King who have been given permission to ask boldly.

Wednesday Matthew 6:9-13

The Lord's Prayer teaches us to pray God's name, God's kingdom, God's will—not our convenience. When we say 'Your kingdom come,' we are aligning our desires with the advance of God's reign in the world, praying that El Paso and the nations would see the gospel proclaimed and believed. This is the antidote to prayer that shrinks into personal comfort; we are called to pray as ambassadors, not as isolated individuals.

Thursday Isaiah 60:1-3

Isaiah's vision of Zion's light drawing the nations captures what Paul means when he calls us to pray for boldness in proclaiming the gospel. Our prayers for boldness are not prayers for personal courage but prayers that our church would shine with the light of Christ so brightly that our neighbors are drawn to see what God has done. We are not hiding the light—we are holding it up, praying that the world will see and come.

Friday Ephesians 2:8-9

We pray for boldness in proclamation because the gospel is not our work but God's gracious work—we are simply witnesses to what he has done. This frees us from the burden of converting anyone; our role is to speak the good news faithfully and pray that God would open hearts. When we pray for the advance of the kingdom, we are trusting that God's grace, not our eloquence, does the saving work.

Pray together this week

Prayer: The Weapon of All-Prayer

Father, we come before you as a people called to battle, and we are grateful that you have given us the weapon of all-prayer. We praise you that prayer is not a fragile, precious practice reserved for quiet moments, but a rugged battlefield radio connecting us to our Commander. You are sovereign over all things, and nothing takes you by surprise. You hear every cry of your people, and you answer every godly prayer—whether with 'Yes, now,' 'Yes, soon, but not now,' or 'No, because I have something better.' We stand in awe of your wisdom and your care.

But we confess, Father, that we often treat prayer as optional, as something to add to our lives when we have margin. We confess that we divide ourselves into 'Word people' and 'prayer people,' when you call us to integrate both in every season. We confess that our prayers often stay small, focused on our comfort and our safety, when you have called us to pray boldly for the advance of your kingdom in our city. Forgive us for prayerlessness born of prayerlessness—for the rhythms we have fallen into that make supplication a luxury rather than a necessity.

Yet here is the good news: Christ has already won the victory, and you have seated us with him in the heavenly places. Through his death and resurrection, we have been reconciled to you and given access to your throne. In Jesus, every barrier between us and your ear has been removed. We come now to appropriate this gift—to take up the weapon you have given us and to pray without ceasing for all the saints, for boldness in gospel proclamation, and for the gospel to advance in every corner of our city and our world.

We ask, Lord, that you would awaken in us a hunger to pray. Give us perseverance in intercession for one another—for the spiritual welfare of our brothers and sisters in Christ. Make us bold to pray for open doors for the gospel, for boldness of speech, and for the mystery of Christ to be made known. Help us to see our circumstances—our suffering, our limitations, our struggles—not as obstacles to prayer but as the very context in which you have called us to be faithful. And grant us clarity: that Cross of Grace is your embassy in El Paso, a foretaste of the age to come, sent both to invite the world to see your grace and to go out as your ambassadors.

We commit ourselves to this weapon. We choose to pray. We choose to fight for the kingdom of God on our knees. May our prayers be the evidence of our faith, and may the advance of your gospel in our city be the answer to our prayers. To you be all glory, honor, and dominion—now and forever. Amen.

The Weapon We Actually Have

For the parent

This prompt invites kids to think about what 'weapons' Christians actually use in spiritual life—moving them past the idea that prayer is quiet and precious to seeing it as rugged and powerful. Listen for where they think they're weak or scared, and gently point them toward prayer as their real strength.

In the sermon, Pastor Ricky said prayer is like a battlefield radio connecting us to our Commander—not a precious, fragile thing, but a weapon we can actually use. Think of a time this week when you felt worried, or scared, or like you didn't know what to do. What would it have looked like if you'd picked up that 'radio' and prayed about it right then, instead of waiting or staying quiet?
Works for ages 8+; younger kids can listen and answer with help from a parent ('When were you worried this week?')

Couples · three questions over coffee

Prayer as Warfare: Praying Together for the Kingdom

  1. What did you hear in the sermon about prayer that surprised you or convicted you—especially the idea that prayer is a weapon for spiritual warfare, not just a comfort?
  2. As a couple, where are we tempted to pray small prayers about our own comfort instead of bold prayers for the gospel's advance in our city? What would it look like for us to pray together for our neighbors, our church, and El Paso the way Paul asks?
  3. Who is one person or one situation in our church or community that the Lord has put on your heart? Let's commit to pray for that together this week—will you share with me what you're carrying, so I can pray it back to you?

Memory verse this week

Ephesians 6:18

Praying at all times in the Spirit, with all prayer and supplication. To that end, keep alert with all perseverance, making supplication for all the saints.

Why this verse: This verse is the hinge of the sermon—it establishes prayer as the Christian's primary weapon in spiritual warfare and defines its scope (all times, all prayer, all saints). Memorizing it anchors the listener's weekly practice to Paul's explicit command that prayer is not optional comfort but essential battlefield equipment for every believer's life.
