How to interact with Jesus 101! What breathtaking encounters!
The leper said, "If you will, you are able."
Jesus said, "I will."
I think Jesus likes to be approached like that. It is never a lack of ability that prevents God from responding to my requests.
The centurion cause Jesus to "marvel" at his faith! That's amazing! What would it take for him to marvel at my faith? What would it take for him to say to me, "As your faith, so it will be to you?" Maybe he already does!
