14 How then shall they call on Him in whom they have not believed? And how shall they believe in Him of whom they have not heard? And how shall they hear without preaching?15 And how shall they preach unless they are sent? As it is written, How beautiful [are] the feet of those who preach the gospel of peace and bring glad tidings of good things!16 But [they have] not all obeyed the gospel. For Isaiah says, Lord, who has believed our report?17 Then faith [is] of hearing, and hearing by the Word of God.
