Romans 10:6-10

But the righteousness which is of faith says these words, Say not in your heart, Who will go up to heaven? (that is, to make Christ come down:) Or, Who will go down into the deep? (that is, to make Christ come again from the dead:) But what does it say? The word is near you, in your mouth and in your heart: that is, the word of faith of which we are the preachers: Because, if you say with your mouth that Jesus is Lord, and have faith in your heart that God has made him come back from the dead, you will have salvation: For with the heart man has faith to get righteousness, and with the mouth he says that Jesus is Lord to get salvation.
