'Willingness' in the Bible

So then God’s choice is not dependent on human will, nor on human effort [the totality of human striving], but on God who shows mercy [to whomever He chooses—it is His sovereign gift].

for I know your eagerness [to promote this cause], and I have [proudly] boasted to the people of Macedonia about it, telling them that Achaia has been prepared since last year [for this contribution], and your enthusiasm has inspired the majority of them [to respond].
