On chastisement

For whom the LORD loves He chastens, and scourges every son whom He receives. Hebrews 12:6 (NKJV) 

The earth, the vine, and the olive are in need of chastisement.  When the olive is bruised, then its fruit smells sweet.  When the vine is pruned, then its grapes are good.  When the soil is plowed, its yield is good.  When water is confined in channels, desert places drink of it; brass, silver and gold, when they are burnished, shine.
