A most significant lesson, the parable of the Generous Landowner. Matthew 20:1-15: "Grace is part of the very nature of God, and He cannot change. He is indeed the generous landowner of the parable, continually going to the marketplace of life to find those in need of 'a days wages' so that He can bring them into His vineyard and then reward them out of all proportion to their labors."
