Wooops! You may want to rethink that one.
Matthew 13:33 Another parable spake he unto them; The kingdom of heaven is like unto leaven, which a woman took, and hid in three measures of meal, till the whole was leavened.
The context of the leaven in Galatians 5 is clear:
7 You ran well. Who hindered you from obeying the truth? 8 This persuasion does not come from Him who calls you. 9 A little leaven leavens the whole lump. 10 I have confidence in you, in the Lord, that you will have no other mind; but he who troubles you shall bear his judgment, whoever he is.
