Jesus and his disciples break grain during the Sabbath, infuriating the Pharisees. Jesus goes to discuss the difference between the "religious" mentality of the Pharisees versus what God actually cares about. Jesus argues directly with the Pharisees about their hypocritical religious mentality. For the religious, the focus is following all sorts of external regulations to be seen as righteous before people and seeing this as the way to please God. Jesus came to point out that real righteousness comes from humbly recognizing our inability to meet all the regulations of God's law, but instead to admit our brokenness and ask for forgiveness in faith. God desires to show people compassion rather than needing sacrifices from them.
