When Jesus heard this, he was amazed and said to those following him, "Amen, I say to you, in no one in Israel have I found such faith."
Gospel's Commentary
Today we see the good outcome of asking God "well" and "the best for us". The centurion – an officer of the Roman army - goes right to Jesus: he knows how to ask well. He does it with humility: "Lord, I am not worthy to have you enter under my roof"; He says so with a strong faith: "only say the word and my servant will be healed” In addition, he knows how to ask for "what is good for others": he worries about the lack of health of a servant of his.
--The centurion has stolen Jesus' heart, and there is the result: "You may go; as you have believed, let it be done for you."
