Tragedy of unfaithfulness

The personal tragedy of a marital unfaithfulness becomes a powerful illustration of the greater tragedy of a nation in rebellion against her God. It’s a story of loyal love—between the prophet Hosea and his adulterous wife, Gomer, and between God and His idolatrous people, Israel. Just as Gomer breaks Hosea’s heart by playing the harlot, Israel breaks the heart of her God as she spurns His love. But unconditional love is the theme: Just as Hosea buys his wife out of slavery, God will redeem and restore His people—after a time of purifying punishment. Unconditional love keeps seeking even after it is rejected. Hosea, whose name means salvation, is a prophet from the northern kingdom of Israel, often called Ephraim because that was the dominant tribe in the north as Judah was in the south. He writes with the detail and passion of a native eyewitness to the demise of Israel. “In no prophet is the love of God more clearly demarcated and illustrated than in Hosea” (Walter C. Kaiser Jr., Toward an Old Testament Theology, p. 197).
