Hosea ministered primarily to the northern kingdom of Israel during its final decades. God commanded him to marry Gomer, and the names of their children - Jezreel, Lo-Ruhamah, and Lo-Ammi - carried prophetic messages of judgment. Hosea denounced idolatry, political dependence on foreign powers, moral corruption, and superficial worship. Yet his prophecy repeatedly returns to God's compassion and promised restoration, calling Israel to return to the Lord.
