Parable of Labourers in the Vineyard

In Matthew 20: 1-16 there is a story which seeks to help us understand God's grace through Jesus telling the parable of the workers in the vineyard. There are some aspects of Jesus teaching in this parable that will be hard to receive and challenges our sense of fairness and justice. But, it will also set us free from the rollercoaster of emotions stemming from constantly comparing ourselves, and our lives, with others. Jesus wants us to understand God's grace and its part in the Kingdom of God.
