Hosea 1,The agonizing pain of an unfaithful wife illustrates how God feels when we act like pagans.

Imagine a certain man who loves a certain woman more than anything else in this world. He loves her so much that he marries her and dedicates his life to her happiness and well-being. But while this woman initially responds to his affections, she later turns away from him to become a prostitute. She would rather have adulterous sex with hundreds of men than have the love and security of this man that truly loves her. He keeps taking her from the streets of prostitution and even buys her from slavery in order to take her back as his wife. But she keeps sneaking back into the sick world of being a whore. The story of that certain man is the life of Hosea. Elohim used Hosea as that certain man to illustrate how Israel was unfaithful to Him.
Hosea and Jeremiah were very similar in many respects. They both spoke the heart of God. Jeremiah spoke from heartbreaking experiences of the nation. Hosea spoke from the heartbreaking experiences of his home. Hosea's wife was unfaithful to him and became a whore. He loved her so much that he took her back again. She left him to become a whore again. Speaking from this heartbreaking experience, this man walked out in front of the nation of Israel, with tears streaming down his face saying, "I want you to know how God feels about you, because I feel the same way." This man could speak God's heart because he experienced God's heart toward His people.
