What Good is a Little Bit of Yeast?

I did a word study on the usage of yeast in the Bible.  Here is what I found:

Yeast is used symbolically to represent influence, usually negatively.  Just as a little bit of yeast, permeates dough and produces a noticeable result, so to does influence, be it good or bad.

  • The Bible contains many references to not using yeast in various religious practices, which symbolically shows the removal of sin.
  • Paul compares false teaching to yeast.
  • Another negative connotation is when Jesus says, beware of the yeast of the Pharisees (which is hypocrisy) and also the Sadducees and Herod.
  • In seemingly the only positive usage of yeast in the Bible, Jesus says that the Kingdom of God (that is, the Kingdom of Heaven) is like yeast.
  • In a final reference to yeast Paul uses it as a metaphor for boasting.  Paul talks about getting rid of bread with old yeast (malice and wickedness) and using new bread without yeast (sincerity and truth).
