'Willing' in the Bible

So, for my part, I am ready and eager to preach the gospel also to you who are in Rome.

For I know that good does not live in me, that is, in my flesh. For the willing is present in me, but the doing [of] the good [is] not.

so, then -- not of him who is willing, nor of him who is running, but of God who is doing kindness:

What if God, willing to shew his wrath, and to make his power known, endured with much longsuffering the vessels of wrath fitted to destruction:

And what if he is willing to make known the wealth of his glory on the objects of mercy that he has prepared beforehand for glory --

in order that if God be willing I may come to you with a glad heart, and may enjoy a time of rest with you.
