1. Lest they should be wearied with the Second Epistle as though the first was sufficient, he says that it was not written in vain, because they stood in need of being often stirred up.

2. That ye may be mindful. By these words he intimates that we have enough in the writings of the prophets, and in the gospel, to stir us up, provided we be as diligent as it behoves us, in meditating on them; and that our minds sometimes contract a rust, or become bedimmed through darkness, is…

3. Knowing this first. The participle knowing may be applied to the Apostle, and in this way, “I labor to stir you up for this reason, because I know what and how great is your impending danger from scoffers.” I however prefer this explanation, that the participle is used in place of a verb, as…

4. Where is the promise. It was a dangerous scoff when they insinuated a doubt as to the last resurrection; for when that is taken away, there is no gospel any longer, the power of Christ is brought to nothing, the whole of religion is gone.

5. For this they willingly are ignorant of. By one argument only he confutes the scoff of the ungodly, even by this, that the world once perished by a deluge of waters, when yet it consisted of waters.

It seems, however, strange that he says that the world perished through the deluge, when he had before mentioned the heaven and the earth. To this I answer, that the heaven was then also submerged, that is, the region of the air, which stood open between the two waters.

7. But the heavens and the earth which are now. He does not infer this as the consequence; for his purpose was no other than to dissipate the craftiness of scoffers respecting the perpetual state of nature, and we see many such at this day who being slightly embued with the rudiments of philosophy,…

8. But be not ignorant of this one thing. He now turns to speak to the godly; and he reminds them that when the coming of Christ is the subject, they were to raise upwards their eyes, for by so doing, they would not limit, by their unreasonable wishes, the time appointed by the Lord.

9. But the Lord is not slack, or, delays not. He checks extreme and unreasonable haste by another reason, that is, that the Lord defers his coming that he might invite all mankind to repentance. For our minds are always prurient, and a doubt often creeps in, why he does not come sooner.

10. But the day of the Lord will come. This has been added, that the faithful might be always watching, and not promise to-morrow to themselves. For we all labor under two very different evils – too much haste, and slothfulness.

Heaven and earth, he says, shall pass away for our sakes; is it meet, then, for us to be engrossed with the things of earth, and not, on the contrary, to attend to a holy and godly life? The corruptions of heaven and earth will be purged by fire, while yet as the creatures of God they are pure;…

14. Wherefore. He justly reasons from hope to its effect, or the practice of a godly life; for hope is living and efficacious; therefore it cannot be but that it will attract us to itself.

15. The long-suffering of our Lord. He takes it as granted that Christ defers the day of his coming, because he has a regard for our salvation. He hence animates the faithful, because in a longer delay they have an evidence as to their own salvation.

16. In which are some things. The relative which does not refer to epistles, for it is in the neuter gender. The meaning is, that in the things which he wrote there was sometimes an obscurity, which gave occasion to the unlearned to go astray to their own ruin.

17. Ye, therefore, beloved. After having shewn to the faithful the dangers of which they were to beware, he now concludes by admonishing them to be wise. But he shews that there was need of being watchful, lest they should be overwhelmed.

18. But grow in grace. He also exhorts us to make progress; for it is the only way of persevering, to make continual advances, and not to stand still in the middle of our journey; as though he had said, that they only would be safe who labored to make progress daily.
