Matthew 20:1-16 -Vineyard workers - Jesus uses this parable to demonstrate the principles of God's grace. His grace is offered to everyone regardless of their standing.  It is offered equally and generously to anyone who will say yes.  None of us wants God to be just, we all want to be shown His grace and mercy.  Don't be envious of what God does in the life of others.  Rejoice in the grace and goodness He has shown to you.
