Romans 10:8 KJV
But what saith it? The word is nigh thee, even in thy mouth, and in thy heart: that is, the word of faith, which we preach;
Deuteronomy 30:14 KJV
But the word is very nigh unto thee, in thy mouth, and in thy heart, that thou mayest do it.
Romans 10:9-13 KJV
That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.
 For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.
 For the scripture saith, Whosoever believeth on him shall not be ashamed.
 For there is no difference between the Jew and the Greek: for the same Lord over all is rich unto all that call upon him. (This IS NOT saying that all people’s God is the same . Rather this is saying all who call upon the Lord Jesus Christ. No matter your background or anything, Jesus Christ died for all who will receive the ONLY true salvation. )
 For whosoever shall call upon the name of the Lord shall be saved.
(So, what happened to the orthodox Jew and why do they insist on another temple-a third temple?) READ ON
Romans 10:16-21 KJV
But they have not all obeyed the gospel. For Esaias saith, Lord, who hath believed our report?
 So then faith cometh by hearing, and hearing by the word of God.
 But I say, Have they not heard? Yes verily, their sound went into all the earth, and their words unto the ends of the world.
 But 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.
 But Esaias is very bold, and saith, I was found of them that sought me not; I was made manifest unto them that asked not after me.
 But to Israel he saith, All day long I have stretched forth my hands unto a disobedient and gainsaying people.
COMMENTARY FROM STUDY BIBLE
10:18-20 Many Jews who looked for the Messiah refused to believe in him when he came. God offered his salvation to the Gentiles (“people who were not looking for me”); thus, many Gentiles who didn’t even know about a Messiah found and believed in him. Some religious people are spiritually blind, while those who have never been in a church are sometimes the most responsive to God’s message. Because appearances are deceiving, and we can’t see into people’s hearts, beware of judging beforehand who will respond to the Good News and who will not.
