Romans 10:6-9

6But the righteousness based on faith [which produces a right relationship with Him] says the following: “Do not say in your heart, ‘Who will ascend into Heaven?’ that is, to bring Christ down;

7or, ‘Who will descend into the abyss?’ that is, to bring Christ up from the dead [as if we had to be saved by our own efforts, doing the impossible].”

8But what does it say? “The word is near you, in your mouth and in your heart”—that is, the word [the message, the basis] of faith which we preach—

9because if you acknowledge and confess with your mouth that Jesus is Lord [recognizing His power, authority, and majesty as God], and believe in your heart that God raised Him from the dead, you will be saved.
