Hosea is a rough story. Just as Ezekiel was full of graphic metaphors comparing the nation of Israel to a prostitute, Hosea is about a prophet instructed by God to marry one, who had a difficult time with the concept of fidelity. It's a brutal story. Just as God remains faithful to his adulterous nation, so Hosea has to keep bringing his wife back to stay with him. The book ends with God's promise to continue to take the initiative.
Hosea 14:4 I will heal their disloyalty; I will love them freely, for my anger has turned from them.
5 I will be like the dew to Israel; he shall blossom like the lily, he shall strike root like the forests of Lebanon. 6 His shoots shall spread out; his beauty shall be like the olive tree, and his fragrance like that of Lebanon.
7 They shall again live beneath my shadow, they shall flourish as a garden; they shall blossom like the vine, their fragrance shall be like the wine of Lebanon.
8 O Ephraim, what have I to do with idols? It is I who answer and look after you. I am like an evergreen cypress; your faithfulness comes from me.
9 Those who are wise understand these things; those who are discerning know them. For the ways of the Lord are right, and the upright walk in them, but transgressors stumble in them.
