“Listen! Once there was a man who went out to sow grain. As he scattered the seed in the field, some of it fell along the path, and the birds came and ate it up. Some of it fell on rocky ground, where there was little soil. The seeds soon sprouted, because the soil wasn't deep. Then, when the sun came up, it burned the young plants; and because the roots had not grown deep enough, the plants soon dried up. Some of the seed fell among thorn bushes, which grew up and choked the plants, and they didn't bear grain. But some seeds fell in good soil, and the plants sprouted, grew, and bore grain: some had thirty grains, others sixty, and others one hundred.” And Jesus concluded, “Listen, then, if you have ears!”
“The Kingdom of God is like this. A man scatters seed in his field. He sleeps at night, is up and about during the day, and all the while the seeds are sprouting and growing. Yet he does not know how it happens. The soil itself makes the plants grow and bear fruit; first the tender stalk appears, then the head, and finally the head full of grain. When the grain is ripe, the man starts cutting it with his sickle, because harvest time has come.
“What shall we say the Kingdom of God is like?” asked Jesus. “What parable shall we use to explain it? It is like this. A man takes a mustard seed, the smallest seed in the world, and plants it in the ground. After a while it grows up and becomes the biggest of all plants. It puts out such large branches that the birds come and make their nests in its shade.”
