Peter is referring to Hosea 2:23. He compared the church to God’s people, Israel.
1 Peter 2:9 But you are a chosen race, a royal priesthood, a holy nation, a people for His possession, so that you may proclaim the praises of the One who called you out of darkness into His marvelous light. 10 Once you were not a people, but now you are God’s people; you had not received mercy, but now you have received mercy.
Hosea in chapters. 4–14 comprise descriptions throughout Hosea’s ministry. Hosea document God’s divine outrage for an ugly variety of unfaithfulness:
- Corruption of the religious leaders (Hosea 4:4–10).
- Idolatry of the masses (Hosea 4:11–19); Corruption and idolatry again (Hosea 5:1–7).
- For both Israel’s and Judah’s roles in the disgraceful Syro-Ephraimite War (Hosea 5:8–6:6)
- For breach of their covenant with God through religious syncretism (Hosea 6:7–11; 8:4–6, 11–13; 9:1–9),
- Because of civil strife (Hosea 6:11–7:7; 8:4, 14),
- For their quest for national security by means of alignment with foreign nations (Hosea 7:8–16).
Hosea traces Israel’s spiritual history, including apostasy and faithlessness (Hosea 11:11–13:11). Finally, the book concludes with a call to repentance and the promise of divine forgiveness (ch. 14).
But the character of God is revealed most clearly in Hosea 2:14 – 3:5. Despite His people’s infidelity, apostasy, syncretism, and faithlessness Hosea is instructed to redeem his wife.
Listen to God’s heart for his people:
- “Therefore, behold, I will allure her … and speak kindly to her (Hosea 2:14).
- “I will betroth you to Me forever; Yes, I will betroth you to Me in righteousness and in justice, In loving kindness and in compassion, (Hosea 2:19).
- “And I will betroth you to Me in faithfulness. Then you will know the Lord. (Hosea 2:20).
- “I will also have compassion on her who had not obtained compassion, And I will say to those who were not My people, ‘You are My people!’ And they will say, ‘You are my God!’ ” (Hosea 2:20).
