Matthew 13:18

Give ear, then, to the story of the man who put the seed in the earth.

And he said to them in answer, To you is given the knowledge of the secrets of the kingdom of heaven, but to them it is not given.

And he said to them, If you are not clear about this story, how will you be clear about the others?

Now this is the point of the story: The seed is the word of God.
