Romans 10:8-10

But what does it say? "The word is near you; it is in your mouth and in your heart," that is, the word of faith we are proclaiming: That if you confess with your mouth, "Jesus is Lord," and believe in your heart that God raised him from the dead, you will be saved. For it is with your heart that you believe and are justified, and it is with your mouth that you confess and are saved.

"it is in your mouth and in your heart"

if you confess with your mouth

"Jesus is Lord"

and believe in your heart
John 3:15 "... that everyone who believes in him may have eternal life."

that God raised him from the dead
Acts 2:24 But God raised him from the dead, freeing him from the agony of death, because it was impossible for death to keep its hold on him.

you will be saved
