Romans VerseQuest Commentary — Essay 101: Filled With Goodness and Knowledge

Key Passage: Romans 15:14–16

“And I myself also am persuaded of you, my brethren, that ye also are full of goodness, filled with all knowledge, able also to admonish one another. Nevertheless, brethren, I have written the more boldly unto you in some sort, as putting you in mind, because of the grace that is given to me of God, That I should be the minister of Jesus Christ to the Gentiles, ministering the gospel of God, that the offering up of the Gentiles might be acceptable, being sanctified by the Holy Ghost.” (Romans 15:14–16)

Introduction

Romans 15:14–16 gives us a picture of Christian maturity that would ruin a great deal of modern religious advertising. Paul does not congratulate the Romans because they had developed a polished program, attracted a fashionable crowd, mastered religious entertainment, or learned how to keep everybody pleasantly occupied between Sunday morning and supper. He says they were “full of goodness, filled with all knowledge, able also to admonish one another” (Romans 15:14). There is substance in those words. Goodness without knowledge becomes gullibility. Knowledge without goodness becomes arrogance. Admonition without either one becomes religious bullying. Paul sees believers in whom truth and character have begun to work together. Christianity is not supposed to produce people who merely know more facts about God while remaining as selfish, careless, bitter, and useless as before. Truth is meant to enter the mind, govern the heart, straighten the walk, and make the believer useful in strengthening somebody else.

Yet Paul’s confidence in the Romans does not prevent him from writing boldly to them. That is another mark of biblical ministry. He can commend what is right without pretending nothing needs correction. Modern flattery says, “You are wonderful exactly as you are; please do not let truth disturb the atmosphere.” Paul says, in effect, “I know you possess goodness and knowledge, and I am still going to remind you of what God requires.” Genuine love does not withhold necessary truth because somebody has already made progress. The strongest believers still need Scripture put before them again. Second Peter 1:12 speaks of reminding believers even though they knew the truth and were established in it. The Bible does not assume maturity creates immunity from forgetfulness. A man may know sound doctrine and still need it brought back to the front door of his mind before the flesh sneaks something foolish through the back.

Then Paul describes his own calling in remarkable language: he is “the minister of Jesus Christ to the Gentiles, ministering the gospel of God,” so that “the offering up of the Gentiles might be acceptable, being sanctified by the Holy Ghost” (Romans 15:16). This is not Paul claiming to be a priest who mediates salvation between sinners and God. Jesus Christ alone is the one Mediator, and His sacrifice needs no human assistant. Paul is using sacrificial language to describe gospel ministry: redeemed Gentiles become, figuratively speaking, an offering presented unto God, made acceptable not by Paul’s personality or ceremonial performance but through the sanctifying work of the Holy Ghost. Real ministry therefore aims higher than attendance, applause, information transfer, or perpetual activity. It labors for people transformed by gospel truth and set apart unto God. Busy religion can fill calendars. The Holy Ghost fills lives.

1. “I Myself Also Am Persuaded of You”

Paul begins with confidence rather than suspicion: “And I myself also am persuaded of you, my brethren” (Romans 15:14). That is significant after fourteen chapters containing some of the strongest doctrinal teaching in the New Testament. Paul has exposed universal sin, justification by faith, the failure of flesh, the place of Israel, Christian liberty, the Judgment Seat of Christ, and the obligation of strong believers toward weak ones. Yet he does not address the Roman saints as hopeless spiritual incompetents waiting for an apostle to think for them. He calls them “my brethren” and states that he is persuaded concerning their spiritual condition. Biblical leadership does not have to keep everybody feeling helpless in order to remain important. A faithful minister wants believers to grow until they can stand upon Scripture rather than remain permanently dependent upon his personality.

That word “persuaded” also shows that Paul has grounds for his confidence. He is not distributing empty compliments to soften the audience before asking for money. Romans 1:8 had already acknowledged that their faith was “spoken of throughout the whole world.” Their testimony had evidence behind it. Biblical commendation should work the same way. Flattery praises people for what they are not; godly encouragement recognizes grace that is actually visible. Proverbs 27:2 says, “Let another man praise thee, and not thine own mouth.” The Roman believers did not need to announce their own maturity with banners. Their faith had become observable. Real spiritual substance has a strange habit of becoming visible without a marketing department.

Paul’s confidence also leaves room for growth. Being persuaded of somebody does not mean imagining he has reached sinless perfection. The Romans still needed admonition, reminders, correction, and instruction. Christian maturity is not arriving at a place where nobody can tell you anything. That is usually pride wearing seniority badges. The mature believer remains teachable because the Bible remains deeper than he is. Paul himself says in Philippians 3:12, “Not as though I had already attained, either were already perfect.” If the apostle had not arrived, the rest of us might avoid decorating a chair at the finish line. Confidence in grace and awareness of unfinished growth belong together. God can have done a real work in you while still having plenty left to do.

2. Full of Goodness

Paul says the Roman believers were “full of goodness.” Goodness is not mere niceness. Scripture does not define a good man as somebody who smiles continuously, never disagrees with anybody, and has removed every sharp edge from his convictions. God is good, yet God judges sin, rebukes wickedness, and speaks truth without apology. Biblical goodness has moral substance. It seeks what is right, beneficial, pure, just, and pleasing to God. Galatians 5:22 includes “goodness” among the fruit of the Spirit. That means genuine goodness is not manufactured by public manners while the heart remains rotten. It grows from the Spirit’s work in a believer who is yielding to truth. A polished apple can still be rotten at the core; Christianity begins its work deeper than the skin.

Goodness matters especially because Paul is about to say these believers could admonish one another. Correction in the hands of a man without goodness can become cruelty. Some people enjoy correcting others because correction gives the flesh a temporary throne. They can detect failure the way a buzzard detects roadkill from half a mile up, and they seem equally delighted to circle it. That is not biblical admonition. Galatians 6:1 tells the spiritual believer to restore one overtaken in a fault “in the spirit of meekness.” Goodness wants restoration, not humiliation. It does not enjoy another Christian’s fall because his fall gives us something interesting to discuss. A good man would rather see the brother standing than win the argument about why he fell.

Being “full of goodness” also means Christian character should contain more than prohibitions. Holiness certainly requires separation from sin, but some Christians can tell you fifty things they do not do and leave you wondering what positive grace has replaced them. Ephesians 4 does not merely say stop stealing; it says labor so you may give to him that needeth. It does not merely say stop corrupt communication; it says speak what ministers grace. Biblical sanctification removes poison and grows fruit. A field that contains no weeds is still useless if it produces no crop. God does not save believers merely to become experts in avoidance. He produces people capable of mercy, generosity, truthfulness, patience, faithfulness, courage, and active good. Christianity should leave something growing where the old weeds were pulled.

3. Filled With All Knowledge

Paul next says they were “filled with all knowledge.” Knowledge is essential to Christian maturity because zeal without truth can run quickly in the wrong direction. Romans 10:2 describes Israel as having “a zeal of God, but not according to knowledge.” Sincerity is no substitute for revelation. A man can be sincere enough to walk east while intending to reach a city west of him, but sincerity does not turn the compass around. The Christian needs knowledge of Scripture—what God said, to whom He said it, where it belongs dispensationally, what doctrine it teaches, and how it applies. Second Timothy 2:15 commands the workman to be “rightly dividing the word of truth.” Knowledge that refuses distinctions God made eventually produces confusion with a Bible verse attached to it.

But knowledge carries danger when separated from goodness. First Corinthians 8:1 warns, “Knowledge puffeth up, but charity edifieth.” Knowledge makes a magnificent servant and a dreadful peacock. A man learns a handful of doctrines and suddenly everybody within fifty feet must hear feathers rustling. Paul is not praising knowledge that inflates self-importance. He is describing believers whose knowledge equips them to serve. The Bible was never given merely to win theological trivia contests. Its truth is intended to transform judgment, worship, conduct, relationships, evangelism, and service. If your knowledge of Scripture makes you harder to correct, quicker to despise weaker believers, and more eager to display superiority, you learned the facts while missing the lesson.

“Filled with all knowledge” also suggests breadth rather than obsession with one favorite subject. Some Christians know one doctrine and attempt to make every chapter of the Bible salute it. Give them Genesis and they find their one subject. Give them Revelation and the same subject walks through the door wearing a different hat. Sound believers need the whole counsel of God. Acts 20:27 records Paul saying, “I have not shunned to declare unto you all the counsel of God.” Grace, holiness, prophecy, Christian conduct, justification, the local church, Israel, the gospel, spiritual gifts, prayer, judgment, resurrection, and eternal things all belong in the believer’s diet. Living on one doctrine produces theological malnutrition no matter how accurately that doctrine is taught.

4. Able Also to Admonish One Another

Paul’s next phrase shows what goodness and knowledge are supposed to produce: believers “able also to admonish one another.” Admonition involves warning, correcting, reminding, and placing truth before another person’s mind. Notice that Paul does not reserve this entirely for clergy. Mature believers should become capable of helping one another with Scripture. Colossians 3:16 says, “Let the word of Christ dwell in you richly in all wisdom; teaching and admonishing one another.” The local church is not meant to contain one man with a Bible and hundreds of spiritual spectators who rent pew space. Pastors have a God-given office, but every Christian should grow in truth enough to speak wisely when a brother needs help.

Effective admonition requires both qualifications Paul has already named. Without knowledge, the believer has nothing reliable to say. Without goodness, he may say the right thing for the wrong reason and in the wrong spirit. Truth is a sword, but not every person holding a sword is qualified to perform surgery. Some use Scripture like a club and then blame the bruises on “standing for truth.” The Bible can reprove sharply, and there are times when sharpness is required. Titus 1:13 says, “rebuke them sharply, that they may be sound in the faith.” But the purpose is soundness, not personal satisfaction. Biblical admonition aims at correction, repentance, wisdom, and restoration. If the speaker secretly enjoys the wound more than the healing, something besides the Holy Ghost has entered the operating room.

The phrase “one another” also means the admonisher remains admonishable. Nobody graduates into a caste that gives correction but never receives it. Proverbs 9:9 says, “Give instruction to a wise man, and he will be yet wiser.” A fool resents correction because he thinks correction lowers him; a wise man receives it because truth matters more than ego. Churches become unhealthy when personalities become untouchable. A title is not armor against Scripture. Paul confronted Peter when Peter’s conduct threatened gospel truth (Galatians 2:11–14). If an apostle could require public correction, the rest of us may survive somebody pointing out that we were wrong. The man who cannot be admonished should stop congratulating himself on being qualified to admonish others.

5. Written More Boldly, Putting You in Mind

Romans 15:15 says, “Nevertheless, brethren, I have written the more boldly unto you in some sort, as putting you in mind.” Paul’s earlier commendation does not make bold teaching unnecessary. Mature believers still need reminders because truth can be known without being presently operative in the mind. The problem is not always ignorance; sometimes it is forgetfulness. Israel repeatedly forgot God’s works. Peter wrote to stir believers up “by putting you in remembrance” (2 Peter 1:13). Paul tells Timothy to “put the brethren in remembrance” of certain truths (1 Timothy 4:6). The Bible repeats important doctrines because human beings possess a remarkable ability to remember trivial injuries from fifteen years ago while forgetting a commandment they read yesterday morning.

Boldness is therefore not contrary to love. A minister who loves people enough to tell them only what they enjoy hearing loves their approval more than their souls. Second Timothy 4:2 commands preaching “with all longsuffering and doctrine,” but it also includes “reprove, rebuke, exhort.” Christianity cannot be sustained on compliments alone. A surgeon who refuses to mention the tumor because the patient prefers positive conversation is not compassionate. Paul can tell the Romans they are full of goodness and knowledge and then write boldly because encouragement and correction belong in the same ministry. God’s Word knows when to comfort the afflicted and when to afflict the comfortable.

Paul explains that this boldness arises “because of the grace that is given to me of God.” He does not speak boldly because he enjoys authority for its own sake. His ministry is stewardship grounded in grace. First Corinthians 15:10 says, “by the grace of God I am what I am.” Paul never forgot that the persecutor had become an apostle by mercy. That memory keeps authority from turning into vanity. A minister who remembers grace can preach hard without pretending he invented the truth. He is a messenger, not the Author. Heaven did not hire preachers to edit God’s mail according to local opinion. Their task is to deliver it faithfully and remember that the postman did not write the letter.

6. The Minister of Jesus Christ to the Gentiles

Paul identifies his calling: “That I should be the minister of Jesus Christ to the Gentiles” (Romans 15:16). This agrees with his repeated description of his distinctive apostleship. Romans 11:13 says, “I am the apostle of the Gentiles.” Galatians 2 records recognition that the gospel of the uncircumcision had been committed unto Paul as Peter’s ministry centered upon the circumcision. That does not mean Paul never preached to Jews or that Peter never dealt with Gentiles. Acts itself disproves such wooden oversimplification. It means God gave Paul a distinctive apostolic stewardship in connection with the Gentiles and the revelation concerning the body of Christ. Right division respects that calling instead of flattening every apostle into identical assignments.

His designation as a “minister of Jesus Christ” is also important. Paul does not minister himself. He is not building a personality cult under his own name. First Corinthians 3:5 asks, “Who then is Paul, and who is Apollos, but ministers by whom ye believed?” A minister is a servant. That title has suffered considerable inflation whenever men treat ministry as a ladder for personal importance. The apostle who carried revelation to the Gentile world still described himself in service language. A preacher may have a platform without having a throne. Christ owns the throne. The moment ministry becomes primarily about protecting the minister’s image, increasing his visibility, or ensuring everybody recognizes his importance, the servant has begun measuring himself for the Master’s robe.

The goal of Gentile ministry is gospel fruit, not cultural conquest. Paul is “ministering the gospel of God.” The gospel is not improving civilization until lost people become respectable enough for heaven. It is the good news that Christ died for our sins, was buried, and rose again the third day according to the Scriptures (1 Corinthians 15:3–4). A Gentile does not need to become a Jew before being saved, nor does he enter salvation through Israel’s law. He comes by grace through faith in Jesus Christ. Ephesians 2:8–9 leaves human boasting outside the door. The gospel does not polish Adam; it announces what the last Adam accomplished. Ministry that loses that center may remain religiously busy while becoming spiritually unemployed.

7. The Offering Sanctified by the Holy Ghost

Paul describes his gospel labor in sacrificial language: “that the offering up of the Gentiles might be acceptable, being sanctified by the Holy Ghost” (Romans 15:16). The picture is striking. His Gentile converts are viewed as an offering presented unto God. Paul is not offering them as a literal priest under Israel’s Levitical system, and he is certainly not acting as a mediator whose ceremony makes sinners acceptable to God. First Timothy 2:5 says plainly, “there is one God, and one mediator between God and men, the man Christ Jesus.” Hebrews makes clear that Christ’s sacrifice is once for all. Paul’s language is ministry imagery: the fruit of gospel labor becomes something devoted to God, set apart by the Holy Ghost.

That phrase “being sanctified by the Holy Ghost” removes human boasting from ministry results. Paul preached; God sanctified. Paul ministered the gospel; the Holy Ghost performed the inward work no preacher can manufacture. First Corinthians 6:11 tells believers, “ye are washed, but ye are sanctified, but ye are justified in the name of the Lord Jesus, and by the Spirit of our God.” Human ministry has instruments—preaching, teaching, admonition, prayer, example—but spiritual transformation belongs to God. You can pressure people into outward conformity, train them to repeat religious vocabulary, and organize them into ceaseless activity without producing sanctification. Flesh can learn church manners. Only God can perform spiritual work worthy of eternity.

This gives us a searching measure for ministry success. Are people merely informed, or are they becoming holy? Are they entertained, or edified? Are they busy, or fruitful? Are they attached to a personality, or established in Christ? Do they know more Scripture while obeying less of it? A warehouse can be full and still contain nothing alive. Churches can function the same way. Paul desired an offering “acceptable” to God. Heaven’s approval mattered more than impressive statistics. Ministry should aim to present believers whose lives increasingly belong to God—consciences instructed, minds renewed, conduct purified, doctrine established, love deepened, and service governed by the Holy Ghost. The scoreboard of earth counts heads. The Judgment Seat examines what was built.

Conclusion

Romans 15:14–16 gives us a picture of believers who possessed both character and content: “full of goodness, filled with all knowledge, able also to admonish one another.” That is mature Christianity. Goodness keeps knowledge from becoming proud. Knowledge keeps goodness from becoming gullible. Together they make believers capable of strengthening one another through truth. The local church should not function like an auditorium filled with permanent dependents who know only enough Bible to locate the seat they normally occupy. It should produce men and women increasingly able to understand Scripture, recognize error, encourage the fainthearted, warn the careless, restore the fallen, defend sound doctrine, and help one another walk with Jesus Christ. The goal of teaching is not merely fuller notebooks. It is stronger saints.

Paul also demonstrates what genuine ministry sounds like. He commends the Romans, yet writes boldly. He trusts their maturity, yet reminds them. He exercises authority, yet recognizes that his ministry came by grace. He serves Jesus Christ rather than himself and understands his distinctive calling to the Gentiles. There is nothing flimsy about his ministry and nothing theatrical about it. He does not confuse kindness with silence, boldness with arrogance, activity with fruit, or position with personal greatness. He speaks as a man who knows he has been given a stewardship and will answer to the One who gave it. Every Christian servant would benefit from remembering that ministry is borrowed work done with borrowed strength for another Person’s glory.

And the final goal towers above all religious busyness: “that the offering up of the Gentiles might be acceptable, being sanctified by the Holy Ghost.” That is ministry worth giving a life to. Not merely collecting listeners, filling calendars, multiplying programs, or producing religious consumers, but seeing sinners saved and believers set apart unto God through the Spirit’s work. The preacher cannot sanctify them. The program cannot sanctify them. The crowd cannot sanctify them. The Holy Ghost does the work through truth received in faith. Real ministry therefore keeps preaching the gospel, teaching the Book, admonishing the saints, depending upon grace, and trusting God for what human hands cannot produce. A church can be busy enough to wear out the carpet and still accomplish little that eternity recognizes. Better to have the Holy Ghost produce one acceptable offering than the flesh manufacture a warehouse full of religious noise.
