1 Peter 4:18 reproduces the Greek form of Proverbs 11:31 concerning the righteous, ungodly, and sinner.

The opening trial-of-faith image—testing, fire/gold, praise/glory, and Christ’s revelation—returns in chapter 4’s fiery trial, sharing in Christ’s sufferings, glory, and rejoicing at his revelation.

The “spiritual house” built from living stones in 2:5 reappears as “the house of God” where judgment begins in 4:17.

Peter first calls suffering for righteousness blessed and forbids fear/shameful reaction; chapter 4 returns to suffering for Christ’s name and explicitly says not to be ashamed.

Chapter 4 joins Christ’s sufferings with coming glory; Peter opens chapter 5 as a witness of Christ’s sufferings and a participant in the glory about to be revealed.

Ezekiel’s temple judgment begins at God’s sanctuary. Peter says judgment begins at the house of God, strongly reusing the biblical pattern that divine judgment starts with God’s own household before moving outward.

Isaiah says the Spirit of the LORD rests upon the promised Davidic figure; Peter tells suffering believers that the Spirit of glory and of God rests upon them. The shared “Spirit rests upon” language is a probable Isaiah-shaped echo, not an explicit quotation.
