Francis and and his brothers could have been killed spreading the Gospel. In bringing near the kingdom of heaven, the brothers were engaging in one of the oldest of dramas in which the battle between darkness and light is played out. It was not so much a battle in which they fought the darkness, as it was the ongoing battle with themselves to keep bearing the light, to keep bringing near the kingdom and not giving up, even when they were rejected. For even in rejection they are bringing near the kingdom. And even if they were martyred for proclaiming these words of Jesus, they were not overcome by darkness; they were yielding to the light.
