14 How then shall they call on Him into whom they do not believe? And how shall they believe Him of whom they have not heard? And how shall they hear without preaching?

15 And how shall they preach if they are not sent? As it is written: How beautiful are the feet of those preaching the gospel of peace, bringing glad tidings of good things.

16 But they have not all obeyed the gospel, for Isaiah says, Lord, who believes our report?

17 So then faith is of hearing, and hearing through the Word of God.
