Thank God that He is unfair.
So often, we attempt to hold God in our debt, assuming that somehow he "owes" us something for all that we have given up to follow him. In Matthew 19:27, Peter asks, "We've given up everything to follow you. What will we get out of it?"
Jesus answered with the Parable of the Vineyard Workers-- five groups of workers who work differing hours but are paid the same. Probably not the answer Peter was looking for. Those who follow Christ from the convenience of twenty-first century Christianity would reap the same eternal reward as the man who would die a violent death hanging upside down on a cross. The unclean Gentiles would experience the blessings of the Kingdom of God.
But the parable isn't really about the workers at all. It's about the master of the estate. It's not about the inequity of payment to the workers; it's about the gracious unfairness of God. It's about his extravagant, unexpected, and irrational generosity giving more that what is deserved. God is not fair. He is ridiculously generous.
When is the last time you have thanked God for being unfair?
