Jesus tells this story:
A guy who needs workers, hires people all day long. At the end of the day, he lines them all up. The guy that worked 12 hours in the hot sun–he gets a full wage. The guy hired on at the last hour as the sun was setting…he gets a full wage, too (Matthew 20:1-16).
In a normal business, that wouldn’t be fair.
We sense this, the inherent unfairness, when things like money and work aren’t equal.
I believe this is why Jesus used this example.
It’s supposed to make us think about unfairness, because the kingdom of heaven isn’t fair.
But it’s not unfair in the sense of favoring one person over another. It’s unfair because none of us should be there at all.
And that’s the thought that should be stuck in our mind.
