'Willing' in the Bible

One day there came a leper to Jesus entreating Him, and pleading on his knees. "If you are willing," he said, "you are able to cleanse me."

Moved with pity Jesus reached out His hand and touched him. "I am willing," He said; "be cleansed."

Be wakeful, all of you, and keep on praying, that you may not come into temptation: the spirit is right willing, but the body is frail."
