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 7

7:10 And the pride of Israel testifieth to his face: and they do not return to the LORD their God, nor seek him for all this.
