Today's reading is a series of related parables that Jesus told, along with an explanation of why he often taught others through the symbolism and metaphor of parables. In these, Jesus relies on a single image -- the seed -- to connect with people who were well acquainted with growing food. In these stories are glimpses of the Kingdom of God, especially through teaching itself. Some will hear the story of Jesus and become immediately excited at the latest fad, some will dismiss it out of hand, but some will take heart and pay attention. For these people, great growth and opportunities await.
