“The last will be first, and the first will be last”
Jesus usually taught by using metaphors drawn from the daily life of his day. But he always added a twist to bring out the message. The secret of the parables is to look for the twist. It was common to see migrant farm workers looking for hire. The farmer would need large numbers to harvest his crop. The fact that he would return seeking more laborers is not unreasonable. The twist to the story is the fact that he chooses to give everyone the same pay. In real life his largess would be ruinous. The next time no one would show up early. But this story is not about earthly wage practices. It is about God's generosity in giving everyone of us the same amount of heaven. There are no back seats in paradise--we will all get equal love.
