'Willing' in the Bible

While He was in one of the cities, behold, there was a man covered with leprosy; and when he saw Jesus, he fell on his face and implored Him, saying, “Lord, if You are willing, You can make me clean.”

And He stretched out His hand and touched him, saying, “I am willing; be cleansed.” And immediately the leprosy left him.

But he became angry and was not willing to go in; and his father came out and began pleading with him.

saying, “Father, if You are willing, remove this cup from Me; yet not My will, but Yours be done.”
