2 Peter 3

This is now, beloved, the second letter that I have written to you; and in both of them I stir up your sincere mind by reminding you

that you should remember the words which were spoken before by the holy prophets and the commandment of us, the apostles of the Lord and Savior,

knowing this first, that in the last days mockers will come, walking after their own lusts

and saying, “Where is the promise of his coming? For, from the day that the fathers fell asleep, all things continue as they were from the beginning of the creation.”

For they willfully forget that there were heavens from of old, and an earth formed out of water and amid water by the word of God,

by which means the world that existed then, being overflowed with water, perished.

But the heavens that exist now and the earth, by the same word have been stored up for fire, being reserved against the day of judgment and destruction of ungodly men.

But don’t forget this one thing, beloved, that one day is with the Lord as a thousand years, and a thousand years as one day.

The Lord is not slow concerning his promise, as some count slowness; but he is patient with us, not wishing that anyone should perish, but that all should come to repentance.

But the day of the Lord will come as a thief in the night, in which the heavens will pass away with a great noise, and the elements will be dissolved with fervent heat; and the earth and the works that are in it will be burned up.

Therefore, since all these things will be destroyed like this, what kind of people ought you to be in holy living and godliness,

looking for and earnestly desiring the coming of the day of God, which will cause the burning heavens to be dissolved, and the elements will melt with fervent heat?

But, according to his promise, we look for new heavens and a new earth, in which righteousness dwells.

Therefore, beloved, seeing that you look for these things, be diligent to be found in peace, without defect and blameless in his sight.

Regard the patience of our Lord as salvation; even as our beloved brother Paul also, according to the wisdom given to him, wrote to you,

as also in all of his letters, speaking in them of these things. In those, there are some things that are hard to understand, which the ignorant and unsettled twist, as they also do to the other Scriptures, to their own destruction.

You therefore, beloved, knowing these things beforehand, beware, lest being carried away with the error of the wicked, you fall from your own steadfastness.

But grow in the grace and knowledge of our Lord and Savior Jesus Christ. To him be the glory both now and forever. Amen.

Chapter overviewAI-generated

Overview. This chapter is an exhortation to steadfastness in the face of skepticism and delay, as Peter warns believers about mockers who will ridicule the promised return of Christ. He affirms that God’s timing is not human timing, that the final judgment is certain, and that the present creation will be destroyed by fire and replaced with new heavens and a new earth. The chapter closes with a call to holy living, doctrinal vigilance, and growth in grace.

Flow.

Peter begins by reminding believers of apostolic and prophetic warnings, especially the coming of mockers in the last days who deny Christ’s return based on apparent continuity in nature.
He refutes their skepticism by appealing to divine judgment in the past (the flood) and future (destruction by fire), grounded in God’s sovereign word.
He explains God’s patience not as delay but as mercy, giving time for repentance, before describing the sudden and cataclysmic day of the Lord.
From this, he urges holy living, discernment in the face of false teaching, and spiritual growth, especially in light of Paul’s writings, which some distort to their ruin.

Connections. Following chapter 2, which exposed false teachers who deny Christ’s lordship and bring destructive heresies, this chapter reinforces the need for discernment by focusing on the certainty of future judgment and Christ’s return. It shifts from describing internal corruption to equipping believers against unbelief rooted in the world’s apparent stability. The eschatological confidence and call to purity in this chapter prepare for the transition to the pastoral epistles and the final exhortations found in the broader New Testament corpus, especially those addressing perseverance and the end times, such as Jude and Revelation.

What it teaches. The chapter upholds the authority of divine revelation (both prophetic and apostolic), the reality of future resurrection and judgment (WCF 3.3, 3.7), and the doctrine of God’s eternal decrees carried out in time. It affirms that God’s slowness to judge is a sign of mercy, not failure (HC LD 10), and that creation itself will be renewed after judgment, fulfilling the promise of a new heavens and earth where righteousness dwells (WCF 12.2; BC Art. 37). The warning against twisting Scripture underscores the danger of heresy and the necessity of interpreting Scripture in line with the analogy of faith (; cf. WCF 1.9).

Apply. Pursue growth in grace and truth so that you stand firm in the face of error and endure in hope of the coming day of God.
