34 Jesus always used stories and illustrations like these when speaking to the crowds. In fact, he never spoke to them without using such parables. 35 This fulfilled what God had spoken through the prophet: "I will speak to you in parables. I will explain things hidden since the creation of the world. "

Commentary on Matthew 13:31-35
(Read Matthew 13:31-35)
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?
