'Willing' in the Bible

And behold, a leper approached [and] worshiped him, saying, "Lord, if you are willing, you are able to make me clean."

And extending his hand he touched him, saying, "I am willing, be clean." And immediately his leprosy was cleansed.

and if you are willing to accept [it], he is Elijah, the one who is going to come.

And they tie up heavy burdens and put [them] on people's shoulders, but [they] themselves are not willing with their finger to move them

"Jerusalem, Jerusalem, who kills the prophets and stones those who are sent to her! How many times I wanted to gather your children together {the way} a hen gathers her young together under [her] wings, and you were not willing!

[and] said, "What are you willing to give me if I in turn deliver him to you?" So they set out for him thirty silver coins.

Stay awake and pray that you will not enter into temptation. The spirit [is] willing, but the flesh [is] weak!"
