Romans 12: Unity In Christ

Romans 12: Unity In Christ 

Collin Leong. November 28, 2025


(v1-2) A Living Sacrifice

(v1-2) Paul asked the believers, by the mercies of God, to present their bodies as a living sacrifice, holy and acceptable to God, which is their spiritual worship. Do not conformed to this world, but be transformed by the renewal of their minds, in order to test and discern what is the will of God, what is good and acceptable and perfect. 

Exp: (v1) The motivation to sacrifice our bodies is the mercy of God, which points back to the many facets of God’s saving work Paul has just expounded: justification, adoption, reconciliation, the gift of the Spirit, the promise of glory, and God’s faithfulness to Israel. Sacrificial living is not coerced; it’s the grateful response to mercy already received. Worship flows from grace.

The words "to present" (paristemi) is a verb used for offering sacrifices at the altar. The bodies are not the physical flesh, but the whole embodied self—actions, daily conduct, lived existence. It’s a way of saying: your entire life is the offering. Just as sacrifices had to be pure and pleasing, so the believer’s life must align with God’s will.

In v2, we need to be transformed by the renewal of our mind, in order to do what is right to God. Only then we are capable to assess whether the any messages from the world (or even "Christians") are good and acceptable and perfect to God. 

(v3-8) Gifts of Grace

Paul told them not to think of themselves more highly than they ought to think, but think with sober judgment, each according to the measure of faith that God has assigned. For the physical body have many member that do not have the same functions. They, as a body of Christ, are individually members of the body. We are given gifts that defer according to the grace given to us, let's use them - if prophecy, in proportion to our faith; if service, in our serving; the one who teaches, in his teaching; exhorting in his exhortation; contributes in generosity; leads, in zeal; acts of mercy, with cheerfulness. 

Exp: Paul is addressing people who thinks that they are higher than the rest. Perhaps some of them has "greater" gifts than others. They think that leadership is more important than those who provides services. Just like our bodies, we would not let our little finger to be chopped off. We treat all members of our bodies are important. After all, our gifts are given to us through the faith appointed by God to each of us. Faith is the capacity for gifts. We should not say “My faith is greater”; Paul says, “Your faith is measured out by God — so think soberly.”  Even our faith in God for our salvation do not comes from ourselves - see Philippians 1:29, Ephesians 2:8.

Paul listed 7 gifts:  

GiftPurposePractical Meaning
ProphecySpeaking God’s
truth into
situations		Discernment and proclamation aligned with faith.
Practically: offering Spirit-led insight, encouragement, or correction to guide the community.
Service
(diakonia)		Meeting practical needsTangible acts of help—feeding, assisting, organizing. Practically: volunteering, supporting logistics, caring for the vulnerable.
TeachingExplaining and grounding truthClarifying Scripture and doctrine.
Practically: leading Bible studies, mentoring, making complex truths accessible.
Exhortation (paraklēsis)Encouraging and urgingMotivating others to persevere and grow.
Practically: counseling, inspiring, comforting, urging toward obedience.
Giving (metadidōmi)Sharing resources generouslyProviding material support with simplicity.
Practically: financial generosity, sharing possessions, supporting missions without ulterior motives.
Leading (proistēmi)Guiding and organizingDirecting with diligence and care.
Practically: overseeing ministries, coordinating efforts, managing responsibly.
Mercy
(eleos)		Showing compassionExtending kindness to the suffering.
Practically: visiting the sick, comforting the grieving, serving with cheerfulness.

These seven gifts are Paul’s blueprint for a community where worship is lived out through diverse, grace-enabled roles. Each gift is communal: They are not for self-promotion but for building up the body. Each gift is embodied: They are lived out in daily actions, not abstract concepts. Each gift is grace-based: They flow from God’s mercy, not human achievement. Each believer embodies sacrifice (v1) and transformation (v2) by exercising their gift in everyday life.


(v9-21) Marks of The True Christian

Paul lists a several ethical behaviors and dispositions to do and not to do, that each Christian should do. They function as moral qualities (virtues) and practical actions. The list is relational - how to treat others inside and outside the church.

To do:
  1. Love must be genuine (v9)
  2. Hold fast to what is good (v9)
  3. Love one another with brotherly affection (v10)
  4. Outdo one another in showing honor (v10)
  5. Be fervent in spirit (v11)
  6. Serve the Lord (v11)
  7. Rejoice in hope (v12)
  8. Be patient in tribulation (v12)
  9. Be constant in prayer (v12)
  10. Contribute to the needs of the saints (v13)
  11. Seek to show hospitality (v13)
  12. Bless those who persecute you, do not curse them (v14)
  13. Rejoice with those who rejoice (v15)
  14. Weep with those who weep (v15)
  15. Live in harmony with one another (v16)
  16. Live peaceably with all (v18)
  17. "If your enemy is hungry, feed him; if he is thirsty, give him something to drink. In doing this you will heap burning coals on his head." (Prov 25:21-22)
Not to do:
  1. Abhor what is evil (v9)
  2. Do not be slothful in zeal (v11)
  3. Do not be haughty, but associate with the lowly (v16)
  4. Never be wise in your own sight (v16)
  5. Repay no one evil for evil, but give thought to do what is honorable in the sight of all (v17)
  6. Never avenge yourselves, but leave it to the wrath of God, for it is written "Vengeance is mine, I will repay, says the Lord." (Deut. 32:35). (v19)
  7. Do not be overcome by evil, but overcome evil with good.

These instructions, if it is done and becomes a habit, will shape Christian character and form a person’s moral identity.

Key Messages

Romans 12 shifts from theological exposition to practical exhortation. Paul urges believers to live transformed lives in response to God’s mercy. The chapter emphasizes presenting oneself as a living sacrifice, cultivating humility, exercising spiritual gifts, and embodying genuine love in community. It is a blueprint for Christian ethics—showing how faith translates into daily conduct.

1. Present Your Bodies as Living Sacrifices (vv.1–2)

  • Believers are called to offer themselves wholly to God, not through ritual sacrifices but through daily obedience.

  • Transformation comes by renewing the mind, resisting conformity to the world, and discerning God’s will.

Application: Worship is not confined to church services—it’s a lifestyle. Align your thoughts, choices, and actions with God’s purposes, letting His truth reshape your perspective.

2. Humility and Unity in the Body of Christ (vv.3–8)

  • Paul warns against pride, urging sober self-assessment according to the measure of faith God has given.

  • The church is one body with many members, each with distinct gifts meant for service.

  • Gifts—whether teaching, serving, leading, or encouraging—must be exercised faithfully and humbly.

Application: Recognize your role in the community of faith. Serve with humility, valuing others’ contributions, and use your gifts diligently for the good of all.

3. Genuine Love and Ethical Living (vv.9–13)

  • Love must be sincere, rejecting evil and clinging to good.

  • Believers are called to honor one another, be fervent in spirit, patient in affliction, and devoted to prayer.

  • Hospitality and generosity are marks of authentic Christian love.

Application: Let love be the guiding principle in relationships. Practice kindness, perseverance, and generosity, showing Christ’s love in tangible ways.

4. Responding to Hostility with Grace (vv.14–21)

  • Paul instructs believers to bless persecutors, live in harmony, and avoid vengeance.

  • Evil is overcome not by retaliation but by doing good.

  • The climax: “Do not be overcome by evil, but overcome evil with good.”

Application: In conflict, choose peace over revenge. Trust God’s justice, and respond to hostility with kindness. This radical ethic demonstrates the power of the gospel in action.

Romans 12 is essentially Paul’s “living manifesto” for Christian conduct: worship through daily life, humility in community, love in action, and grace under pressure.

Romans 15: Unity In Glorifying God Collin Leong. December 4, 2025 (v1-7) Accept One Another (v1-7) We who are strong have an obligation to bear with the failings of the weak, and not to please ourselves. Let each of us please his neighbor for his good, to build him up. For Christ did not please himself - "The reproaches of those who reproached you fell on me." (Psalm 69:9) . For whatever was written in the past was written for our instruction, that through endurance and encouragement of the scriptures we might have hope. May the God of endurance and encouragement grant you to live in such harmony with one another, an accord with Christ Jesus, that together you may with on voice glorify the God and Father of our Lord Jesus Christ.

Romans 3: We are Justified Freely by His Grace

Romans 3: We are  Justified Freely by His Grace Collin Leong.  June 29, 2025 (v1-8) God's Faithfulness (v1-4) Paul said that being a Jew is advantageous and there is value is circumcision. Jews have been entrusted with the very words of God. Those who are unfaithful will not nullify God's faithfulness. God will always be true, it is we that are liars. It's written: “So that you may be proved right when you speak and prevail when you judge.”   Paul's quote is taken from Psalm 51:4 - "Against you, you only, have I sinned and done what is evil in your sight; so you are right in your verdict and justified when you judge."   In Psalm 51, David acknowledges that his sin (after the Bathsheba incident) proves God right in judging him. David doesn’t blame God—he affirms that God’s judgment is just, even when it condemns him. In other words, Paul is saying that God's truth and faithfulness will not be compromised by human failure. David's unfaithfulness proves t...

Dec 8, 2025 (v1-16) Personal Greetings Paul mentioned a several names that he knows, to thank them and asked the Roman church to greet them.  (v1-2) Sister Phoebe , a servant of the church at Cenchreae, that they may welcome her in the Lord, worthy of the saints, and help her in whatever she may need, for she has been a patron of many and of Paul himself.  Exp:  Scholars widely believe Phoebe was entrusted to deliver Paul’s letter to the Romans. In the ancient world, the letter carrier often read the letter aloud and explained its meaning, which implies Phoebe may have been one of the earliest interpreters of Romans (v3-5a) Greet Prisca (Priscilla) and Aquila , my fellow workers in Christ Jesus, who risked their necks for my life, to whom not only I give thanks but all the churches of the Gentiles as well.
