Hosea is the first book of the twelve minor prophets. Because the times are outwardly prosperous, idolatry prevails and immorality is rampant. Hosea urges a return to God in order that He may show mercy and forgiveness.

Hosea 4

4:12 My people ask counsel at their stocks, and their staff declareth unto them: for the spirit of whoredoms hath caused them to err, and they have gone a whoring from under their God.
