2 Peter 3:13 → Isaiah 65:17

Peter's hope — "in keeping with God's promise, we are looking forward to a new heaven and a new earth, where righteousness dwells" (2 Pet 3:13) — directly takes up Isaiah's oracle, "For behold, I will create new heavens and a new earth. The former things will not be remembered, nor will they come to mind" (Isa 65:17; cf. the closing inclusio at 66:22). In its original setting Isaiah's word is the bright apex of the Book of Comfort's consolation strand: Yahweh's reply to a ruined Jerusalem is not the restoration of the old but the creation (bārāʾ, the Gen 1:1 verb) of the new. The method is Promise-Fulfillment, not typology — Peter names the link himself with κατὰ τὸ ἐπάγγελμα αὐτοῦ, "according to his promise," and Isaiah's oracle is a verbal divine pledge awaiting realization, not a person, event, or institution that corresponds to and is escalated in Christ (the anti-default test). There is no citation formula, so the Reference Type is Allusion, but Peter reproduces Isaiah's distinctive phrase verbatim. His one interpretive addition — "where righteousness dwells" — reads Isaiah's new creation morally as well as cosmically: the renewed cosmos is not a refurbished habitat only but a realm purged of the ungodliness 2 Peter has been combating, the settled home of the justified. The "former things" Isaiah says will not be remembered are, in Peter's framing, the present heavens and earth "reserved for fire" (3:7) — judgment clearing the way for new creation as the flood once did (3:5–7). The hope is already-and-not-yet: pledged in Christ, awaited at his return. The telos is desire, not bare prediction: Peter grounds the summons to holiness (3:11) in the promised home where righteousness is at last at home, and the Christ who will dwell there with his people is himself the joy that makes the new earth worth the waiting — the new creation is desirable because He is in it.
