Romans 10:9 & 10
that if you confess with your mouth Jesus as Lord, and believe in your heart that God raised Him from the dead, you shall be saved; for with the heart man believes, resulting in righteousness, and with the mouth he confesses, resulting in salvation.
1 Timothy 2:5
For there is one God, one mediator also between God and men, the man, Christ Jesus who gave Himself as a ransom for all.
