31 He put before them another parable: "The kingdom of heaven is like a mustard seed that someone took and sowed in his field; 32 it is the smallest of all the seeds, but when it has grown it is the greatest of shrubs and becomes a tree, so that the birds of the air come and make nests in its branches."
33 He told them another parable: "The kingdom of heaven is like yeast that a woman took and mixed in with three measures of flour until all of it was leavened."

The scope of the parable of the seed sown, is to show that the beginnings of the gospel would be small, but its latter end would greatly increase; in this way the work of grace in the heart, the kingdom of God within us, would be carried on. In the soul where grace truly is, it will grow really; though perhaps at first not to be discerned, it will at last come to great strength and usefulness. The preaching of the gospel works like leaven in the hearts of those who receive it. The leaven works certainly, so does the word, yet gradually. It works silently, and without being seen, Romans 6:13. From these parables we are taught to expect a gradual progress; therefore let us inquire, Are we growing in grace? and in holy principles and habits?
