10For with the heart man believeth so as to obtain righteousness, and with the mouth professeth so as to obtain salvation.
11For the Scripture saith, “Whoever believeth in him shall not be put to shame.”
12For there is no difference between Jew and Greek; for one and the same is Lord over all, rich to all that call upon him.
13For “every one who calleth 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 men preach, unless they are sent forth? as it is written, “How beautiful are the feet of those who bring glad tidings of peace, who bring glad tidings of good things!”
16But they did not all hearken to the glad tidings. For Isaiah saith, “Lord, who hath believed what he hath heard from us?”
17Faith then cometh by hearing, and hearing by the word of God.
