Romans 10:6-9

6But the righteousness based on faith says, "Do not say in your heart, 'Who will ascend into heaven?'" (that is, to bring Christ down)

7"or 'Who will descend into the abyss?'" (that is, to bring Christ up from the dead).

8But what does it say? "The word is near you, in your mouth and in your heart" (that is, the word of faith that we proclaim);

9because, 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.
