That's funny you use Romans 10:17 in the context of Gospel preaching here, and when I used it to prove faith doesn't come from us, you stated Romans 10:17 was not in the context of the Gospel to the lost.
But now it is all of a sudden in a context of Gospel preaching to the lost?
Go figure.
Faith comes from where? You? Nope. Or from hearing the Words of Christ? Yes. It certainly does not come from us. It came from His Word.
God does the speaking, we have to do the HEARING.
Luke 8:18 Take heed therefore how ye hear: for whosoever hath, to him shall be given; and whosoever hath not, from him shall be taken even that which he seemeth to have.
Jesus warned his disciples to be careful what they hear. This makes no sense unless they had control over what they chose to listen to, and what they refused to listen to.
And Jesus shows how grace works, to those who will hear God's word and believe it, more will be given. But to those who do not believe, even that which was given them (revelation) shall be taken away.
