Young's Literal Translation: "But what doth it say? `Nigh thee is the saying -- in thy mouth, and in thy heart:' that is, the saying of the faith, that we preach; that if thou mayest confess with thy mouth the Lord Jesus, and mayest believe in thy heart that God did raise Him out of the dead, thou shalt be saved, for with the heart doth `one' believe to righteousness, and with the mouth is confession made to salvation; for the Writing saith, `Every one who is believing on Him shall not be ashamed,' for there is no difference between Jew and Greek, for the same Lord of all `is' rich to all those calling upon Him, for every one -- whoever shall call upon the name of the Lord, he shall be saved."
New International Version: "But what does it say? “The word is near you; it is in your mouth and in your heart,” that is, the message concerning faith that we proclaim: If you declare with your mouth, “Jesus is Lord,” and believe in your heart that God raised Him from the dead, you will be saved. For it is with your heart that you believe and are justified, and it is with your mouth that you profess your faith and are saved. As Scripture says, “Anyone who believes in Him will never be put to shame.” For there is no difference between Jew and Gentile—the same Lord is Lord of all and richly blesses all who call on Him, for, “Everyone who calls on the name of the Lord will be saved.”
New Living Translation: "In fact, it says, “The message is very close at hand; it is on your lips and in your heart.” And that message is the very message about faith that we preach: If you confess with your mouth that Jesus is Lord and believe in your heart that God raised Him from the dead, you will be saved. For it is by believing in your heart that you are made right with God, and it is by confessing with your mouth that you are saved. As the Scriptures tell us, “Anyone who trusts in Him will never be disgraced.” Jew and Gentile are the same in this respect. They have the same Lord, who gives generously to all who call on Him. For “Everyone who calls on the name of the LORD will be saved.”
If Jesus is not your Lord, you are not born again!
