Mark 4:26-29

Then Jesus said, “The kingdom of God is like someone who plants seed in the ground. Night and day, whether the person is asleep or awake, the seed still grows, but the person does not know how it grows. By itself the earth produces grain. First the plant grows, then the head, and then all the grain in the head. When the grain is ready, the farmer cuts it, because this is the harvest time.”
