1. Petrus 2:9

Ye are a chosen generation - The titles formerly given to the whole Jewish Church, i.e. to all the Israelites without exception, all who were in the covenant of God by circumcision, whether they were holy persons or not, are here given to Christians in general in the same way; i.e. to all who believed in Christ, whether Jews or Gentiles, and who received baptism in the name of the Father, and of the Son, and of the Holy Ghost. The Israelites were a chosen or elected race, to be a special people unto the Lord their God, above all people that were upon the face of the earth, Deu 7:6. They were also a royal priesthood, or what Moses calls a kingdom of priests, Exo 19:6. For all were called to sacrifice to God; and he is represented to be the King of that people, and Father of those of whom he was king; therefore they were all royal. They were a holy nation, Exo 19:6; for they were separated from all the people of the earth, that they might worship the one only true God, and abstain from the abominations that were in the heathen world. They were also a peculiar people, λαος εις περιποιησιν, a purchased people; סגלה segullah, a private property, belonging to God Almighty, Deu 7:6; none other having any right in them, and they being under obligation to God alone. All these things the apostle applies to the Christians, to whom indeed they belong, in their spirit and essence, in such a way as they could not belong to the Hebrews of old. But they were called to this state of salvation out of darkness - idolatry, superstition, and ungodliness, into his marvellous light - the Gospel dispensation, which, in reference to the discoveries it had made of God, his nature, will, and gracious promises towards mankind, differed as much from the preceding dispensation of the Jews, as the li…

Contrast in the privileges and destinies of believers. Compare the similar contrast with the preceding context. chosen--"elect" of God, even as Christ your Lord is. generation--implying the unity of spiritual origin and kindred of believers as a class distinct from the world. royal--kingly. Believers, like Christ, the antitypical Melchisedec, are at once kings and priests. Israel, in a spiritual sense, was designed to be the same among the nations of the earth. The full realization on earth of this, both to the literal and the spiritual Israel, is as yet future. holy nation--antitypical to Israel. peculiar people--literally, "a people for an acquisition," that is, whom God chose to be peculiarly His: Act 20:28, "purchased," literally, "acquired." God's "peculiar treasure" above others. show forth--publish abroad. Not their own praises but His. They have no reason to magnify themselves above others for once they had been in the same darkness, and only through God's grace had been brought to the light which they must henceforth show forth to others. praises--Greek, "virtues," "excellencies": His glory, mercy (Pe1 2:10), goodness (Greek, Pe1 2:3; Num 14:17-18; Isa 63:7). The same term is applied to believers, Pe2 1:5. of him who hath called you-- (Pe2 1:3). out of darkness--of heathen and even Jewish ignorance, sin, and misery, and so out of the dominion of the prince of darkness. marvellous--Peter still has in mind Psa 118:23. light--It is called "His," that is, God's. Only the (spiritual) light is created by God, not darkness. In Isa 45:7, it is physical darkness and evil, not moral, that God is said to create, the punishment of sin, not sin itself. Peter, with characteristic boldness, brands as darkness what all the world calls light; reason, without the Holy Spirit, in…

Which in time were not a people,.... A "Loammi" being put upon them; see Hos 1:9 to which the apostle here refers: God's elect, whether among Jews or Gentiles, were, from eternity, his chosen people, and his covenant people; and, as such, were given to Christ, and they became his people, and his care and charge; and he saved them by his obedience, sufferings, and death, and redeemed them to himself, a peculiar people: but then, before conversion, they are not a people formed by God for himself, and his praise; nor Christ's willing people, either to be saved by him, or to serve him; nor are they, nor can they be truly known by themselves, or others, to be the people of God: the Syriac version gives the true sense of the phrase, by rendering it "these who before were not" "reckoned or accounted a people"; that is, by others: but are now the people of God; being regenerated, called, and sanctified, they are avouched by God to be his people; they have the witness of the Spirit to their spirits, that they are the people of God; they can then claim their relation to God, and are known, acknowledged, and called the people of God, by others: which had not obtained mercy, but now have obtained mercy; being called formerly, Loruhamah, Hos 1:6 which passages the apostle has in view: before conversion there is mercy in God's heart towards his elect, and so there is in the covenant of grace, and which was shown in the provision of his Son, as a Saviour, in the mission of him, and redemption by him; but this is not manifested to them, until they are begotten again, according to abundant mercy, and then they obtain mercy; having in their regeneration an evident display of the mercy of God towards them, and an application of his pardoning grace and mercy, through the blood of his Son,…

The general exhortation to holiness is continued, and enforced by several reasons taken from the foundation on which Christians are built, Jesus Christ, and from their spiritual blessings and privileges in him. The means of obtaining it, the word of God, is recommended, and all contrary qualities are condemned (Pe1 2:1-12). Particular directions are given how subjects ought to obey the magistrates, and servants their masters, patiently suffering in well doing, in imitation of Christ (Pe1 2:13 to the end).

2:9 Peter applies descriptions of the Israelites in the Old Testament (see, e.g., Exod 19:5-6) to his primarily Gentile audience, indicating that they—like all Christians—are truly God’s people in the new covenant era.
