On my pray-as-you-go podcast today (http://ax.itunes.apple.com/WebObjects/MZStore.woa/wa/viewPodcast?id=129950199) the reading was two sayings of Jesus about the Kingdom of God. The first was the mustard seed, the second the yeast in the bread.
It reminded me of a sermon that I heard a while ago about how shocking it would have been to the Jewish audience when Jesus describes the Kingdom of God as a non-kosher pearl.
This brings me to the yeast/leaven example. In most of scripture yeast is a symbol of sin. It’s what you have to rid your house of at Passover. St Paul uses the example in some of his epistles. Even Jesus says ‘beware of the yeast of the Pharisees’. So why does he describe the Kingdom of God as a bit of yeast that works its was through the whole batch of dough? Was he being deliberately provocative, almost saying ‘the Kingdom of God is not what you think’?
Are there any Bible scholars out there that can help me with this? Please respond in the comments below. This has really intrigued me!
