The Parable of the Growing Seed

Mark 4:26-29

And he said: So is the kingdom of God, as if a man should cast seed into the earth,

And should sleep, and rise, night and day, and the seed should spring, and grow up whilst he knoweth not.

For the earth of itself bringeth forth fruit, first the blade, then the ear, afterwards the full corn in the ear.

And when the fruit is brought forth, immediately he putteth in the sickle, because the harvest is come.
