Parable of the Mustard Seed
31 Here is another illustration Jesus used: "The Kingdom of Heaven is like a mustard seed planted in a field.32 It is the smallest of all seeds, but it becomes the largest of garden plants; it grows into a tree, and birds come and make nests in its branches."
34 Jesus always used stories and illustrations like these when speaking to the crowds. In fact, he never spoke to them without using such parables.
