Read Matthew 12 today.

Matthew 12:1-2, 9-10, 22-24, 38-39 NLT[1] At about that time Jesus was walking through some grainfields on the Sabbath. His disciples were hungry, so they began breaking off some heads of grain and eating them. [2] But some Pharisees saw them do it and protested, “Look, your disciples are breaking the law by harvesting grain on the Sabbath.”
[9] Then Jesus went over to their synagogue, [10] where he noticed a man with a deformed hand. The Pharisees asked Jesus, “Does the law permit a person to work by healing on the Sabbath?” (They were hoping he would say yes, so they could bring charges against him.)
[22] Then a demon-possessed man, who was blind and couldn’t speak, was brought to Jesus. He healed the man so that he could both speak and see. [23] The crowd was amazed and asked, “Could it be that Jesus is the Son of David, the Messiah?” [24] But when the Pharisees heard about the miracle, they said, “No wonder he can cast out demons. He gets his power from Satan, the prince of demons.”
[38] One day some teachers of religious law and Pharisees came to Jesus and said, “Teacher, we want you to show us a miraculous sign to prove your authority.”
[39] But Jesus replied, “Only an evil, adulterous generation would demand a miraculous sign; but the only sign I will give them is the sign of the prophet Jonah.
This chapter includes many stories about the growing conflict between the religious leaders and Jesus. Reading these stories reminds me how difficult it is to deal someone who believes they already have all the answers.
