I seriously doubt that the story of the early and late workers in the vineyard would make very many folks' Top Ten Parables list. It's the parable most everyone loves to hate. And for good reason! The parable runs against the grain of one of our most deeply cherished values, the value of hard work and just reward: The more you work and the more productive you are, the more you ought to get paid. Let's face it: this parable is just not fair! But, then again, as someone once said, "God is good, but life isn't fair!"
I remember well the first sermon I preached on this passage from Matthew's Gospel. An elder of the church I was serving at that time came up to me after the service and said, "Preacher, of all the texts you had to pick from, you had to choose my least favorite parable in all of the New Testament! Jesus should have known better than to tell something as unfair as this! The next time you decide to preach about that one, please let me know in advance so I can get an early tee time that Sunday!"
