How to Build a Church - Part 1

Apr 19, 2026    Rick Keller

What does it really mean to build a church that reflects the heart of God? Romans 12:9-13 gives us a blueprint that has nothing to do with buildings, budgets, or branding, and everything to do with the condition of our hearts. We're challenged to examine whether our love is genuine or hypocritical, whether we're truly hating evil while clinging to what is good. The early Roman Christians faced persecution for refusing to participate in the violent entertainment of the Colosseum, willing to die rather than compromise their convictions about the sanctity of human life. Their example forces us to ask uncomfortable questions about our own entertainment choices and cultural compromises. The passage moves outward from personal character to how we treat one another in the church, calling us to outdo each other in showing honor rather than seeking it for ourselves. We're reminded that discipleship isn't complicated—it's simply showing someone who doesn't know what we do how to do what we do. The triplet of rejoicing in hope, being patient in affliction, and being constant in prayer reminds us that God hears every prayer offered according to His will, even when we're crying out from our own dark caves like David did. The most comforting songs ever written came from the darkest places, teaching us that our afflictions may have purposes beyond what we can see.


**SERMON NOTES – Romans 12:9–12 – “How to Build a Church, Part 1”**


---


### I. The Flow of Romans 12 

- Chapters 1–11: Doctrine. 

- Chapter 12: Practice—radiating outward: 

 - v9 – Character (heart) 

 - vv10–13 – Church 

 - vv14–21 – Culture 

 - ch.13 – Civics 


---


### II. Triplet #1 – v9: Heart Posture 

**“Let love be genuine. Abhor what is evil; hold fast to what is good.”** 

1. **Let love be genuine (without hypocrisy)** 

  - No fake “churchy” love (“I love them in the Lord” but actually resent them). 

  - Jesus and Judas: a kiss of betrayal as a picture of hypocritical love. 

  - God’s love to us is genuine; ours toward others must reflect that.


2. **Abhor what is evil** 

  - Love and hate are connected: 

   - Love my wife → hate what harms the marriage. 

   - Love truth → hate lies. 

  - Evil = what is anti-God; Scripture defines what God hates (e.g., Prov 6). 

  - Romans believers refused violent “entertainment” of the Coliseum; were persecuted for it.


3. **Hold fast to what is good** 

  - “Koleo” – glue yourself to good; active pursuit, not just passive avoidance. 

  - Culture desensitizes (pumpkin/duck & frog/boiling water illustrations). 

  - Early Christians chose costly conviction over easy compromise.

### III. Triplet #2 – v10–11: Church Life 

**“Love one another with brotherly affection. Outdo one another in showing honor.”** 

- Honor = lead in preferring others, pushing them forward. 

- Model: leaders who serve (Ezek 34 – God rebukes shepherds who feed themselves). 

- Jesus hates “Nicolaitan” spirit: overbearing leaders/laity (Rev 2:6). 

- True leadership: elders serving meals, men of high status doing lowly tasks. 

- Discipleship = show others how to do what you do, then release them (Apollos & Priscilla/Aquila; Paul’s attitude toward Apollos). 


**“Do not be slothful in zeal, be fervent in spirit, serve the Lord.”** 

- Never lazy; work hard; serve enthusiastically. 

- “Sunday comes whether you’re ready or not” – faithfulness in preparation. 

- Every “small” task (coffee, parking, kids’ ministry) is a spiritual service when done unto the Lord. 

- Warning: don’t serve in a controlling, joyless way that repels helpers.

### IV. Triplet #3 – v12: Suffering & Prayer 

**“Rejoice in hope, be patient in tribulation, be constant in prayer.”** 

1. **Rejoice in hope** – confidence in God’s promises not yet seen (Heb 11:1). 

2. **Patient in tribulation** – Bible assumes suffering, doesn’t erase it. 

  - Roman believers faced lions and fires; ours may be different but real. 

3. **Constant in prayer** – steady, honest pouring out of the heart (Psalms as model). 

  - Many Psalms (e.g., David in caves) birthed from deep affliction. 

  - Prodigal son: father doesn’t follow into sin, but never stops praying and watching.

## PRACTICAL APPLICATIONS

1. Identify one relationship where your “love” has been hypocritical; confess and seek a step toward genuine love. 

2. Audit your media/entertainment: what are you being desensitized to? Choose one concrete change this week. 

3. Look for one person in church to honor publicly or privately—email, text, or conversation that pushes them forward. 

4. If you serve, invite someone to do it with you and intentionally show them how. Move from “worker” to “discipler.” 

5. Name one ongoing affliction; commit to a simple daily prayer rhythm (e.g., morning & night) for it for 30 days.

## DISCUSSION QUESTIONS

1. Where are you most tempted to show “polite hypocrisy” instead of genuine love? 

2. How do you practically distinguish between loving people and hating evil? 

3. What forms of entertainment do you think most dull our hatred of evil today? 

4. Who has honored or discipled you in the church, and how did it shape you? 

5. Are you more prone to laziness or to over-controlling in service? Why? 

6. What “cave” season have you walked through, and how did God meet you there? 

7. What long-term prayer have you nearly given up on, and how might Romans 12:12 call you to persevere?
