Luke 7:6-10
When he was still quite far from the house, the captain sent friends to tell him, "Master, you don't have to go to all this trouble. I'm not that good a person, you know. I'd be embarrassed for you to come to my house, 7 even embarrassed to come to you in person. Just give the order and my servant will get well. 8 I'm a man under orders; I also give orders. I tell one soldier, 'Go,' and he goes; another, 'Come,' and he comes; my slave, 'Do this,' and he does it."
9 Taken aback, Jesus addressed the accompanying crowd: "I've yet to come across this kind of simple trust anywhere in Israel, the very people who are supposed to know about God and how he works." 10 When the messengers got back home, they found the servant up and well.

This is the kind of faith that we should have!
