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

7:14 And they have not cried unto me with their heart, when they howled upon their beds: they assemble themselves for corn and wine, and they rebel against me.
