Large crowds followed Jesus when he came down from the hillside [after delivering the Sermon on the Mount]. There was a leper who came and knelt in front of him. “Sir,” he said, “if you want to, you can make me clean.” (Matthew 8:1,2)
We can really just stop right there with the impossible loveliness of that statement: the fact that the least person in that whole countryside, a lonely leper, so understands Jesus' reputation and heart that he immediately addresses Him in such a tender way: "Sir, if you want to, you can make me clean."
"If you want to..." He places this whole exchange at the level of Jesus' desire, Jesus' heart, Jesus' plan, Jesus' will. I think we often pray the words "If it's your will" like we're shooting prayer-arrows into some unknown darkness; this man spoke the word "will" while looking directly into Jesus' eyes. He would know the heart and mind and will and want of Jesus right now: "If you want to..."
"...you can make me clean." It's right there inside You, Jesus. All the wondrous power of the Godhead, every ounce of the creative energy that formed the heavens and the earth, is native to Your human frame. If You want to, this is easy for You. I don't have to strain to improve Your will or Your power. Here I am and here You are: "Sir, if you want to, you can make me clean."
Friends, I think this leprous man's life is the perfect model for how our own prayer-life should go. What a combination of boldness, belief, familiarity and expectancy!
