Let's look at it in context; instead of paraphrasing it to fit your wishes.
(CLV) Ro 10:9
that, if ever you should be avowing with your mouth the declaration that Jesus is Lord, (MASTER! Master of what? You! If he's your master you'll listen to him when he tells you to obey his father's words) and should be believing (If Adam believed in YHWH instead of Satan; He's still be in the Garden) in your heart that God rouses Him from among the dead, you shall be saved. (He was raised because he was obedient. He calls us to follow his example.)
(CLV) Ro 10:10
For with the heart it is believed for righteousness, yet with the mouth it is avowed for salvation.
