In Matthew 11:16-19 Jesus describes the generation that is rejecting him. He describes them as children sitting in a marketplace and demanding that others dance and mourn according to their whims. It is a picture of a generation that seeks to demand God conform to them rather than be conformed to the image of Christ. This caused the people to complain about John being overly strict with what he eats and drinks and to complain about Jesus that he was not so strict. Such is unbelief in every age. People seek to set up their own views of God and adjust their understanding of the Bible to fit their preconceived notions. True faith, however, comes when the Word of God is received humbly.
