What is their mission? Healing to the sick, life to those afflicted, welcome and re-entry to those excluded, liberation to those oppressed in body or in spirit. The little ones. They who travel around interrupting us bring a clear message. Jesus calls us to do things that make no sense, that work against all reason. And, even more strangely, we won't erase the suffering or solve the problems.
But we must listen and become messengers ourselves. We must be ready, open, and willing to be interrupted.
