Jesus said, “The kingdom of God is like a man who scatters seeds on the ground.  He sleeps at night and is awake during the day.  The seeds sprout and grow, although the man doesn’t know how.  The ground produces grain by itself. First the green blade appears, then the head, then the head full of grain.  As soon as the grain is ready, he cuts it with a sickle, because harvest time has come.”

(Mark 4:26-29 -- GW)
