'Willing' in the Bible

But I will come to you soon, if the Lord is willing, and I will find out not only the talk of these arrogant people, but also their power.

But I (not the Lord) say to the rest: If any brother has an unbelieving wife and she is willing to live with him, he must not leave her.

Also, if any woman has an unbelieving husband and he is willing to live with her, she must not leave her husband.

for if willing I do this, I have a reward; and if unwillingly -- with a stewardship I have been entrusted!

About our brother Apollos: I strongly urged him to come to you with the brothers, but he was not at all willing to come now. However, he will come when he has an opportunity.
