The Parable of the Yeast

Here Jesus compares the kingdom of heaven with yeast - it really doesn't make much sense until you put it with the preceding parable about the mustard seed

"The Kingdom of Heaven is like a mustard seed planted in a field. It is the smallest of all seeds, but it becomes the largest of garden plants and grows into a tree where birds can come and find shelter in its branches."

Only then does the context enhance it such that you can understand that it is referring to how we can have the tiniest pinch of knowledge of Christ mixed into our hearts it can grow and spread throughout us causing us to fill up the lives of others around us. Note in this reference the yeast is good as opposed to when he uses it to refer to the pharisees
