Luke 7:7
That is why I did not even consider myself worthy to come to you. But say the word, and my servant will be healed — the military insight: the centurion understands authority. He did not consider himself worthy to come in person — the intermediaries communicated both respect and humility. But say the word and my servant will be healed: the radical faith in the word's sufficiency. No touch, no presence, no physical contact — just the word of the one with authority.
