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 5

5:6 They shall go with their flocks and with their herds to seek the LORD; but they shall not find him; he hath withdrawn himself from them.
