mark 4:26 And he said, So is the kingdom of God, as if a man should cast seed into the ground; - Free Bible Online

      Parable of the Seed Growing We Know Not How (Mr 4:26-29).

      This beautiful parable is peculiar to Mark. Its design is to teach the Imperceptible Growth of the word sown in the heart, from its earliest stage of development to the ripest fruits of practical righteousness.

      26, 27. So is the kingdom of God, as if a man should cast seed into the ground; and should sleep, and rise night and day--go about his other ordinary occupations, leaving it to the well-known laws of vegetation under the genial influences of heaven. This is the sense of "the earth bringing forth fruit of herself," in Mr 4:27.
