Romans 10:9-11

9If you declare with your mouth, “Jesus is Lord,” and believe in your heart that God raised him from the dead, you will be saved. 10For 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. 11As Scripture says, “Anyone who believes in him will never be put to shame.” Isaiah 28:16 (see Septuagint)
