SPIRITUAL INSIGHT, Dr. Samuel Lee
GUARD AGAINST DESTRUCTIVE TEACHING
Passage: Matthew 16:1~12  
Key verse: 12
The Demand for a Sign(A)
16 The Pharisees and Sadducees(B) came to Jesus and tested him by asking him to show them a sign from heaven.(C)
2 He replied, “When evening comes, you say, ‘It will be fair weather, for the sky is red,’ 3 and in the morning, ‘Today it will be stormy, for the sky is red and overcast.’ You know how to interpret the appearance of the sky, but you cannot interpret the signs of the times.[a](D) 4 A wicked and adulterous generation looks for a sign, but none will be given it except the sign of Jonah.”(E) Jesus then left them and went away.
The Yeast of the Pharisees and Sadducees
5 When they went across the lake, the disciples forgot to take bread. 6 “Be careful,” Jesus said to them. “Be on your guard against the yeast of the Pharisees and Sadducees.”(F)
7 They discussed this among themselves and said, “It is because we didn’t bring any bread.”
8 Aware of their discussion, Jesus asked, “You of little faith,(G) why are you talking among yourselves about having no bread? 9 Do you still not understand? Don’t you remember the five loaves for the five thousand, and how many basketfuls you gathered?(H) 10 Or the seven loaves for the four thousand, and how many basketfuls you gathered?(I) 11 How is it you don’t understand that I was not talking to you about bread? But be on your guard against the yeast of the Pharisees and Sadducees.” 12 Then they understood that he was not telling them to guard against the yeast used in bread, but against the teaching of the Pharisees and Sadducees.(J)

The Pharisees and Sadducees were usually enemies, but they were united in their total disdain for Jesus. They tested Jesus by asking him for a sign. Jesus had already performed many signs. Another sign would not lead them to faith but further skepticism about Jesus. Jesus rebuked them. They knew how to interpret the sky for the weather but would not interpret Jesus' signs. May Jesus' signs to us deepen our faith in him.
2. Be on your guard (5-12)
Jesus warned his disciples about the yeast of the Pharisees and Sadducees. The disciples' minds immediately went to their lack of bread. Jesus was not talking about bread. He reminded them that twice he was able to feed thousands with just a few loaves. They ought not to worry about bread. Jesus was talking about the teaching of the Pharisees and Sadducees. Their corrupted teaching was imperceptible but could also puff up a listener with pride. Any teaching that puts the focus on us and not on God is spiritually dangerous.
