Mark 4:26-30
Parable of the Seed
26 And He was saying, “The kingdom of God is like a man who casts seed upon the soil;
27 and he goes to bed at night and gets up by day, and the seed sprouts and grows—how, he himself does not know.
28 The soil produces crops by itself; first the blade, then the head, then the mature grain in the head.
29 But when the crop permits, he immediately (a)(A)puts in the sickle, because the harvest has come.”
