We can at once see that the Sower did not vary and the seed did not vary. Only one thing varied, and that was the type of soil that received the perfect seed that was sown by the Lord.
"Listen! A sower went out to sow. And as he sowed, some seed fell along the path, and the birds came and devoured it. Other seed fell on rocky ground, where it had not much soil, and immediately it sprang up, since it had no depth of soil; and when the sun rose it was scorched, and since it had no root it withered away. Other seed fell among thorns and the thorns grew up and choked it, and it yielded
no grain. And other seeds fell into good soil and brought forth grain, growing up and increasing and yielding thirtyfold and sixtyfold and a hundredfold. And he said, He who has ears to hear, let him hear."
