'Willing' in the Bible

While Jesus was in one of the towns, a man came to him who was covered with leprosy. When he saw Jesus, he bowed down with his face to the ground and begged him, "Lord, if you are willing, you can make me clean."

So he stretched out his hand and touched him, saying, "I am willing. Be clean!" And immediately the leprosy left him.

"Father, if you are willing, take this cup away from me. Yet not my will but yours be done."
