Sour Grapes & Tumbling Walls - Parable of the Vineyard

The parable of the vineyard and the wicked tenants or husbandmen is a warning to peoples and nations that no wall will protect a society that is abundantly blessed yet continues to bear bad fruit and sour grapes, refusing to give God his due. Security and the peace that passes understanding are the rewards only of those who return thanks in response to God's blessings.
