Mark 4:26-29 - The Parable Of The Seed That Grows By Itself
26 And He said, Thus is the kingdom of God, as a man may cast seed on the ground; 27 and he may sleep, and rise night and day, and the seed germinates and grows, as he does not know. 28 The earth spontaneously brings forth fruit; first the blade, then the ear, then the full corn in the ear. 29 And when the fruit may develop, immediately he thrusts in the sickle, because the harvest is at hand.
