Mark 4:26-29 - The Parable Of The Seed That Grows By Itself
26 He added: The kingdom of God is like this. A man plants seed in the earth. 27 He sleeps and gets up night and day until the plants grow though he has no idea how. 28 The earth gives fruit by itself. First comes the leaf, then the head, then full grain. 29 When the grain is ready he immediately sends men to cut it, because the time for cutting has come.
