The parables of Jesus are an interesting mix. Some of them are mysterious and hard to unlock, such as the one involving the workers who receive the same amount of pay after laboring for differing amounts of time.
Some parables seem to have no hidden qualities and appear quite easy to interpret.
Today's parable seems to be a very straightforward message. The parable focuses on a landowner who leases out a vineyard and receives nothing but disrespect and maltreatment from the tenant farmers. They beat and kill his servants and eventually murder his own son. We listen to this parable and think we have it figured out. The vineyard is the nation of Israel.
