12 for there is no difference between Jew and Greek, for the same Lord of all [is] rich to all those calling upon Him,

13 for every one -- whoever shall call upon the name of the Lord, he shall be saved.`

14 How then shall they call upon [him] in whom they did not believe? and how shall they believe [on him] of whom they did not hear? and how shall they hear apart from one preaching?

15 and how shall they preach, if they may not be sent? according as it hath been written, `How beautiful the feet of those proclaiming good tidings of peace, of those proclaiming good tidings of the good things!`
