Mark 4:26-29 - The Parable Of The Seed That Grows By Itself
26 Jesus also said: "This is what the Kingdom of God is like-- like a man who has scattered seed on the ground, 27 And then sleeps by night and rises by day, while the seed is shooting up and growing--he knows not how. 28 The ground bears the crop of itself--first the blade, then the ear, and then the full grain in the ear; 29 But, as soon as the crop is ready, immediately he 'puts in the sickle because harvest has come'."
