Peter’s two epistles present God’s move from eternity to eternity. Here is a brief look.

In eternity, before creation, God had purposed something in Himself. In His infinite wisdom God knew us before creation and chose us for Himself (1 P 1:2). Something of God’s purpose and our salvation was unveiled through the prophets (1 P 1:10-12).

Jesus Christ was manifested (1 P 1:20), transfigured (2 P 1:16-18), shed His blood for our redemption (1 P 1:18-19, 2:24), and resurrected (1 P 1:3). He is the cornerstone for God’s eternal building (1 P 2:6), and He will come again as the rising Sun (2 P 1:19).

Peter writes about our receiving God’s forgiveness (1 P 1:2), regeneration (1 P 1:3, 23), and baptism (1 P 3:21). He speaks of God’s grace to us (1 P 1:2, 5:12) and our manner of life as Christians including relationships with one another, rejecting worldly and fleshly living to be holy as God is holy (1 Peter 1:15-16), being subject to the government of God while we suffer in this time, and God’s judgement beginning with His household (1 P 4:17).

Peter unveils the day of judgement with the change from the old creation to the new
(2 P 3:10-13). He does not mention New Jerusalem but many phrases point to it.

We have been regenerated “unto a living hope,” and “unto an inheritance, incorruptible and undefiled and unfading, kept in the heavens for you” (1 P 1:3-4). Our ultimate inheritance is to be part of New Jerusalem.

Second Peter 1:1-4 present many blessings from God to us. By these we exercise to develop a life full of Christian virtues (1:5-11). Eventually, “the entrance into the eternal kingdom of our Lord and Savior Jesus Christ will be richly and bountifully supplied to you” (1:11). New Jerusalem is the consummate realization of this eternal kingdom.

Finally, to God “be the glory and the might forever and ever” (1 P 5:11) and to Jesus Christ “be the glory both now and unto the day of eternity” (2 P 3:18). Both point to New Jerusalem, the city “having the glory of God” (Rev. 21:11).
