'Willing' in the Bible

And a leper came to Him and bowed down before Him, and said, “Lord, if You are willing, You can make me clean.”

Jesus stretched out His hand and touched him, saying, “I am willing; be cleansed.” And immediately his leprosy was cleansed.

and said, “What are you willing to give me to betray Him to you?” And they weighed out thirty pieces of silver to him.

Keep watching and praying that you may not enter into temptation; the spirit is willing, but the flesh is weak.”
