Matthew 16:5-12

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.”
 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, 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? ¹⁰ Or the seven loaves for the four thousand, and how many basketfuls you gathered? 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. (NIV)

One of the things that yeast does it cause things to expand or grow. We know that's why the dough rises as it sits before baking. There has been a lot of talk of bread recently for the disciples and so they weren't exactly sure what Jesus was talking about when He mentioned the "yeast of the Pharisees and Sadducees." If any of you have ever made something with bad yeast, it ruins the entire batch. Here is what Jesus is talking about, keep from letting bad things grow in your life.

Stop and think about that for a second, what sorts of things do you allow to "grow" in your life that don't belong there or make you sick (spiritually or physically)? These are the types of things we need to give up and get over because they keep us from having enough room for the good stuff.
