The parable "Growing Seed"
4:26 And he said, So is the kingdom of God, as if a man should cast seed into the ground;
4:27 And should sleep, and rise night and day, and the seed should spring and grow up, he knoweth not how.
4:28 For the earth bringeth forth fruit of herself: first the blade, then the ear after that the full corn in the ear.
4:29 But when the fruit is brought forth, immediately he putteth in the sickle, because the harvest is come.
