Nevertheless we, according to his promise. — “Nevertheless” is too strong, and the emphasis is on “new,” not on “we.” But new heavens and a new earth, wherein dwelleth righteousness, we look for, according to His promise. (Comp. Revelation 21:1.) On the repetition of “look for,” three times in three verses, see above on 2 Peter 2:7. The promise of the new heavens and new earth is given in Isaiah 65:17; Isaiah 66:22. There are two words for “new” in Greek; one looks forward, “young” as opposed to “aged;” the other looks back, “fresh” as opposed to “worn out.” It is the latter word that is used. here and in Revelation 21:1-2. Both are used in Matthew 9:17, but the distinction is not marked in our version — “They put new wine into fresh wine-skins.”
Wherein dwelleth righteousness. — Comp. Isaiah 65:25; Revelation 21:27. Righteousness has its home there; is not a wanderer and changeful guest, as on earth, therefore by righteousness must ye make yourselves worthy of entering therein.
With this whole verse compare 1 Peter 1, where (2 Peter 3:4) a similar thought is expressed with equal beauty, and where (2 Peter 3:13) a similar conclusion is drawn from it. (See next verse.)
