The Lord’s Return Is Certain
Peter begins the final chapter by reminding believers why he writes.
“Beloved, I now write to you this second epistle… to stir up your pure minds by way of reminder.” — 2 Peter 3:1
He urges them to remember:
“…the words which were spoken before by the holy prophets, and of the commandment of us, the apostles…” — 2 Peter 3:2
Peter then warns that in the last days:
“…scoffers will come, walking according to their own lusts.” — 2 Peter 3:3
They will mock Christ’s promised return, saying:
“Where is the promise of His coming?” — 2 Peter 3:4
They assume that because history appears unchanged, God’s promises will never be fulfilled. Peter reminds them that they deliberately ignore two great events:
– God created the world by His Word. – God judged the ancient world through the Flood.
“…the world that then existed perished, being flooded with water.” — 2 Peter 3:6
The same God who judged once will judge again.
“But the heavens and the earth which are now preserved by the same word, are reserved for fire until the day of judgment…” — 2 Peter 3:7
This reminds us that God’s promises are never cancelled by human doubt. The world may mock Christ’s return, but His coming is absolutely certain. History is moving according to God’s perfect plan, not according to human opinion.
God’s Patience Is Salvation
Peter now addresses an important question. Why has Christ not yet returned? He answers:
“But, beloved, do not forget this one thing, that with the Lord one day is as a thousand years, and a thousand years as one day.” — 2 Peter 3:8
God experiences time differently from His creation. Peter explains:
“The Lord is not slack concerning His promise… but is longsuffering toward us…” — 2 Peter 3:9
Why?
“…not willing that any should perish but that all should come to repentance.” — 2 Peter 3:9
Christ’s apparent delay is actually an expression of God’s mercy. Nevertheless:
“But the day of the Lord will come as a thief in the night…” — 2 Peter 3:10
Its arrival will be sudden and unexpected. Peter describes the future judgment.
“…the heavens will pass away with a great noise…” — 2 Peter 3:10
And:
“…the earth and the works that are in it will be burned up.” — 2 Peter 3:10
2 Peter 3 teaches that God’s patience is not weakness but mercy. Every additional day before Christ returns provides another opportunity for people to repent and be saved. Yet His return will come suddenly, making readiness essential.
Live Holy Lives While Waiting
Peter now asks a practical question.
“Therefore, since all these things will be dissolved, what manner of persons ought you to be…” — 2 Peter 3:11
His answer:
“…in holy conduct and godliness.” — 2 Peter 3:11
Believers should live:
“…looking for and hastening the coming of the day of God…” — 2 Peter 3:12
Peter then gives one of Scripture’s glorious promises.
“Nevertheless we, according to His promise, look for new heavens and a new earth in which righteousness dwells.” — 2 Peter 3:13
Because of this future hope:
“…be diligent to be found by Him in peace, without spot and blameless.” — 2 Peter 3:14
Peter also acknowledges Paul’s letters. He writes that Paul wrote:
“…according to the wisdom given to him.” — 2 Peter 3:15
Though some people distort Paul’s writings:
“…as they do also the rest of the Scriptures…” — 2 Peter 3:16
Peter places Paul’s writings alongside the other inspired Scriptures. Finally, Peter warns us:
“…beware lest you also fall from your own steadfastness…” — 2 Peter 3:17
He concludes with one of the New Testament’s great exhortations.
“But grow in the grace and knowledge of our Lord and Savior Jesus Christ…” — 2 Peter 3:18
This reminds us that our future hope should shape our present lives. As we wait for Christ’s return, we pursue holiness, remain grounded in Scripture, guard against deception, and continually grow in our relationship with Jesus Christ.
Deeper Waters
2 Peter 3 brings the letter to its magnificent conclusion by focusing on the certainty of Christ’s return, God’s patient mercy, the coming renewal of creation, and the believer’s responsibility to live holy lives while awaiting that glorious day. Having warned about false teachers in chapter 2, Peter now addresses one of their central errors: denying the future coming of Christ and God’s final judgment.
Peter begins by saying he writes:
**”to stir up your pure minds by way of reminder.”**
Spiritual maturity depends not only upon learning new truths but upon continually remembering God’s revealed truth. Throughout both of his letters, Peter repeatedly reminds us that faithful perseverance comes through holding firmly to God’s Word.
He directs their attention to two equally authoritative sources:
– the holy prophets (the Old Testament), – the apostles (the New Testament witnesses). This beautifully demonstrates the unity of God’s revelation throughout Scripture. Peter warns that:
**”scoffers will come.”**
These mockers are not simply intellectual sceptics. Their rejection of Christ’s return is connected to lifestyle. They are:
**”walking according to their own lusts.”**
If there is no coming judgment, they reason, there is no need for repentance or holy living. They ask:
**”Where is the promise of His coming?”**
Because history appears to continue normally, they conclude that God’s promises have failed. Peter responds by exposing what they deliberately ignore. First:
Creation itself. The universe exists because:
**”the heavens were of old… by the word of God.”**
God created everything through His sovereign command. History therefore has both a divine beginning and a divinely appointed conclusion. Second:
The Flood. Peter reminds them:
**”the world that then existed perished.”**
God has already intervened dramatically in human history through worldwide judgment. The Flood demonstrates that God’s patience does not eliminate His justice. Peter then declares:
**”the heavens and the earth… are reserved for fire.”**
Just as water once served as God’s instrument of judgment, the present creation awaits a future purifying judgment by fire. This judgment is certain because it rests upon:
**”the same word.”**
The God who spoke creation into existence and judged the ancient world will also fulfil every remaining promise concerning the future. Peter next addresses the apparent delay of Christ’s return. He writes:
**”with the Lord one day is as a thousand years.”**
Peter is not providing a mathematical formula for interpreting prophecy. Rather, he emphasises God’s eternal perspective. Unlike human beings, God stands above time. What appears long from our perspective is never delayed from His. Peter then provides the real reason for the delay.
**”The Lord is not slack concerning His promise.”**
God has not forgotten. He has not become unable. He has not changed His mind. Instead:
**”He is longsuffering.”**
The delay reveals extraordinary mercy. Peter says God is:
**”not willing that any should perish but that all should come to repentance.”**
This verse beautifully displays God’s compassionate heart toward sinful humanity. His patience provides opportunity for repentance before the certainty of coming judgment. Nevertheless:
**”the day of the Lord will come as a thief.”**
The imagery emphasises suddenness and unexpectedness rather than secrecy. No one knows the precise moment of Christ’s return. Therefore believers are called to continual readiness. Peter describes the future dissolution of the present creation.
**”the heavens will pass away.”**
**”the elements will melt with fervent heat.”**
The emphasis is not upon scientific detail but upon the complete certainty that the present order of this fallen world will give way to God’s glorious new creation. Peter then asks one of Scripture’s most searching questions:
**”what manner of persons ought you to be?”**
Biblical prophecy is never intended merely to satisfy curiosity about future events. Its purpose is ethical transformation. Because eternity is coming, believers should live:
**”in holy conduct and godliness.”**
Future hope shapes present holiness. Peter even says believers are:
**”looking for and hastening the coming of the day of God.”**
While God’s sovereign timing never changes, faithful Gospel witness, prayer, and holy living participate in His redemptive purposes as history moves toward its appointed climax. Peter then gives one of the Bible’s greatest promises:
**”new heavens and a new earth.”**
This fulfils Isaiah 65–66 and reaches its full expression in Revelation 21–22. Unlike the present fallen world, the new creation will be characterised by:
**”righteousness.”**
Sin, death, suffering, injustice, and evil will never again corrupt God’s creation. This glorious hope motivates present diligence. Believers are to be found:
**”in peace, without spot and blameless.”**
Not because they earn salvation through flawless living, but because Christ’s transforming grace continually shapes their lives as they await His appearing. Peter then makes an important statement about Paul’s writings. He recognises Paul’s God-given wisdom and acknowledges that some passages are difficult to understand. Yet he also says people twist Paul’s letters:
**”as they do also the rest of the Scriptures.”**
This is highly significant. Peter explicitly places Paul’s writings alongside the already recognised Scriptures, providing one of the earliest New Testament testimonies to the divine authority of the apostolic writings. The letter concludes with two final commands. First:
**”beware.”**
False teaching remains a continual danger. Second:
**”grow.”**
The Christian life never reaches a point of spiritual completion in this present age. Growth occurs:
**”in the grace and knowledge of our Lord and Savior Jesus Christ.”**
Grace provides the power. Knowledge deepens the relationship. Together they produce increasing conformity to Christ. Peter ends exactly where the Christian life ultimately belongs:
**”To Him be the glory both now and forever.”**
Everything begins with Christ’s grace, continues through His sustaining power, and concludes with His eternal glory. 2 Peter 3 encourages us to: co.nfidently trust every promise God has made, – refuse to be influenced by those who mock Christ’s return, – recognise God’s patience as an expression of His saving mercy, – live each day with joyful expectancy of Christ’s appearing, – allow future hope to produce present holiness, – eagerly anticipate the new heavens and new earth, – remain grounded in the authority of all Scripture, – carefully avoid distortions of God’s Word, – continually grow in grace and in personal knowledge of Jesus Christ, – and live every aspect of life for His everlasting glory.
Ultimately, 2 Peter 3 points us to Jesus Christ—the Creator through whom all things were made, the patient Saviour who delays judgment so that sinners may repent, the coming King who will return in glory, the righteous Judge before whom every person will stand, and the Lord who will usher in the new heavens and the new earth where righteousness will dwell forever. Until that glorious day, believers are called to stand firm upon His Word, pursue holiness, proclaim His Gospel, grow continually in His grace, and eagerly await the fulfilment of every promise He has spoken.
