Romans 10:8-15

But what does it say? “The Dvar is near you, in your MOUTH and in your HEART.” That is, the Dvar of Emunah which we proclaim. Because if you make hoda'ah (confession) “with your PEH” of Adoneinu Yehoshua, and have emunah “in your LEV” that G-d raised him from the Mesim, you will be delivered. For with the “heart” one has emunah unto being YITZDAK IM HASHEM and with the “mouth” hoda'ah is made unto Yeshu'at Eloheinu. For the Kitvei Hakodesh says, Everyone who has emunah in Him shall not be put to shame. For there is no distinction between Yehudi and Yevani, for the same one is Adon Echad l'chulam (one L-rd over all), rich to all who call upon Him. For V'HAYAH KOL ASHER YIKRA B'SHEM ADONOI (Everyone whoever calls upon the Name of the L-rd — Yoel 3:5 [2:32]) shall be delivered. How therefore 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 someone doing the hatafah (preaching)? And how shall they do the hatafah (preaching) unless they have been sent? As it is written, “How beautiful are the feet of those who preach” Besuras HaGeulah Isa 52:7.
