John Calvin on 2 Peter 3:8

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. For waiting seems very long on this account, because we have our eyes fixed on the shortness of the present life, and we also increase weariness by computing days, hours, and minutes. But when the eternity of God's kingdom comes to our minds, many ages vanish away like so many moments.

This then is what the Apostle calls our attention to, so that we may know that the day of resurrection does not depend on the present flow of time, but on the hidden purpose of God, as though he had said, “Men wish to anticipate God for this reason, because they measure time according to the judgment of their own flesh; and they are by nature inclined to impatience, so that celerity is even delay to them: do ye then ascend in your minds to heaven, and thus time will be to you neither long nor short.”

2 Peter 1:9-13

9. The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance.

9. Non tardat Dominus in promissione, sicuti quidam tarditatem slackness; existimant; sed tolerantem se praebet erga nos, nolens ullos perire, sed omnes ad poenitentiam recipere (aut, colligi, vel, aggregari.)

10. But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burnt up.

10. Veniet autem dies Domini tanquam fur in nocte, in qua coeli in modum procellae transibunt, elementa autem ardore solventur; et terra, quaeque in ea sunt opera ardebunt.

11. Seeing then that all these things shall be dissolved, what manner of persons ought ye to be in all holy conversation and godliness,

11. Quum Haec igitur omnia solvantur, quales oportet nos esse in sanctis conversationibus et pietatibus;

12. Looking for and hasting unto the coming of the day of God, wherein the heavens being on fire shall be dissolved, and the elements shall melt with fervent heat?

12. Expectantes properando adventum diei Dei, propter quem coeli solventur, et elementa ardore consumentur?

13. Nevertheless we, according to his promise, look for new heavens and a new earth, wherein dwelleth righteousness.

13. Novos autem coelos et terram novam juxta promissum ejus expectamus, ín quibus habitat justitia.
