13For whosoever shall call upon the name of the Lord shall be saved. 14How 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 a preacher? 15And how shall they preach, except they be sent? as it is written, How beautiful are the feet of them that preach the gospel of peace, and bring glad tidings of good things! 16But they have not all obeyed the gospel. For Esaias saith, Lord, who hath believed our report?17So then faith cometh by hearing, and hearing by the word of God. 18But I say, Have they not heard? Yes verily, their sound went into all the earth, and their words unto the ends of the world. 19But I say, Did not Israel know? First Moses saith, I will provoke you to jealousy by them that are no people, and by a foolish nation I will anger you.
