'Willing' in the Bible

And a leper came to Him, begging Him and falling on his knees before Him, saying, “If You are willing, You are able to make me clean.”

Moved with compassion [for his suffering], Jesus reached out with His hand and touched him, and said to him, “I am willing; be cleansed.”

Keep [actively] watching and praying so that you do not come into temptation; the spirit is willing, but the body is weak.”
